Abstract:
Extended Classical Mechanics (ECM) refines the classical understanding of force, energy, and mass by incorporating the concept of negative apparent mass. In ECM, the effective force is determined by both observable mass and negative apparent mass, leading to a revised force equation. The framework introduces a novel energy-mass relationship where kinetic energy emerges from variations in potential energy, ensuring consistency with classical conservation laws. This study extends ECM to massless particles, demonstrating that they exhibit an effective mass governed by their negative apparent mass components. The connection between ECM’s kinetic energy formulation and the quantum mechanical energy-frequency relation establishes a fundamental link between classical and quantum descriptions of energy and mass. Furthermore, ECM naturally accounts for repulsive gravitational effects without requiring a cosmological constant, reinforcing the interpretation of negative apparent mass as a fundamental aspect of energy displacement in gravitational fields. The framework is further supported by an analogy with Archimedes’ Principle, providing an intuitive understanding of how mass-energy interactions shape particle dynamics. These findings suggest that ECM offers a predictive and self-consistent alternative to relativistic mass-energy interpretations, shedding new light on massless particle dynamics and the nature of gravitational interactions.

Extended Classical Mechanics: Energy and Mass Considerations
1. Force Considerations in ECM:
The force in Extended Classical Mechanics (ECM) is determined by the interplay of observable mass and negative apparent mass. The force equation is expressed as:
F = {Mᴍ +(−Mᵃᵖᵖ)}aᵉᶠᶠ
where: Mᵉᶠᶠ = {Mᴍ +(−Mᵃᵖᵖ)}, Mᴍ ∝ 1/Mᴍ = -Mᵃᵖᵖ
Significance:
- This equation refines classical force considerations by incorporating negative apparent mass −Mᵃᵖᵖ, which emerges due to gravitational interactions and motion.
- The effective acceleration aᵉᶠᶠ adapts dynamically based on motion or gravitational conditions, ensuring consistency in ECM's mass-energy framework.
- The expression (Mᴍ ∝ 1/Mᴍ) provides a self-consistent relationship between observable mass and its apparent counterpart, reinforcing the analogy with Archimedes' principle.
2. Total Energy Considerations in ECM:
Total energy in ECM consists of both potential and kinetic components, adjusted for mass variations:
Eₜₒₜₐₗ = PE + KE
By incorporating the variation in potential energy:
Eₜₒₜₐₗ = (PE − ΔPE) + ΔPE
where:
- Potential Energy: PE = (PE - ΔPE)
- Kinetic Energy:( KE = ΔPE)
Since in ECM, (ΔPE) corresponds to the energy displaced due to apparent mass effects:
Eₜₒₜₐₗ = PE + KE
⇒ (PE − ΔPE of Mᴍ) + (KE of ΔPE) ≡ (Mᴍ − 1/Mᴍ) + (-Mᵃᵖᵖ)
Here, Potential Energy Component:
(PE − ΔPE of Mᴍ) ≡ (Mᴍ − 1/Mᴍ)
This represents how the variation in potential energy is linked and identically equal to mass effects.
Kinetic Energy Component:
(KE of ΔPE) ≡ (-Mᵃᵖᵖ)
This aligns with the ECM interpretation where kinetic energy arises due to negative apparent mass effects.
Significance:
- Ensures energy conservation by explicitly including mass variations.
- Demonstrates that kinetic energy naturally arises from the variation in potential energy, aligning with the effective mass formulation.
- Strengthens the analogy with fluid displacement, reinforcing the concept of negative apparent mass as a counterpart to conventional mass.
3. Kinetic Energy for Massive Particles in ECM:
For massive particles, kinetic energy is derived from classical principles but adjusted for ECM considerations:
KE = ΔPE = 1/2 Mᴍv²
where:
Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ)
Significance:
- Maintains compatibility with classical mechanics while integrating ECM mass variations.
- Reflects how kinetic energy is influenced by the effective mass, ensuring consistency across different gravitational regimes.
- Provides a basis for extending kinetic energy considerations to cases involving negative apparent mass.
4. Kinetic Energy for Conventionally Massless but Negative Apparent Massive Particles:
For conventionally massless particles in ECM, negative apparent mass contributes to the effective mass as follows:
Mᵉᶠᶠ = −Mᵃᵖᵖ + (−Mᵃᵖᵖ)
Since in ECM:
Mᴍ ⇒ −Mᵃᵖᵖ
it follows that:
Mᵉᶠᶠ = −2Mᵃᵖᵖ
Significance:
- Establishes that even conventionally massless particles possess an effective mass due to their negative apparent mass components.
- Provides a self-consistent framework that supports ECM's interpretation of mass-energy interactions.
- Highlights the role of negative apparent mass in governing the energetic properties of massless particles.
5. Kinetic Energy for Negative Apparent Mass Particles, Including Photons:
For negative apparent mass particles, such as photons, kinetic energy is given by:
KE = 1/2 (−2Mᵃᵖᵖ)c²
where:
v = c
Since:
ΔPE = −Mᵃᵖᵖ.c²
it follows that:
ΔPE/c² = −Mᵃᵖᵖ
Thus:
KE = ΔPE/c² = −Mᵃᵖᵖ
Significance:
- Establishes a direct relationship between kinetic energy and the quantum mechanical frequency relation.
- Demonstrates that photons, despite being conventionally massless, exhibit kinetic energy consistent with ECM’s negative apparent mass framework.
- Reinforces the view that negative apparent mass plays a fundamental role in governing mass-energy interactions at both classical and quantum scales.
6. ECM Kinetic Energy and Quantum Mechanical Frequency Relationship for Negative Apparent Mass Particles:
KE = ΔPE/c² = hf/c² = −Mᵃᵖᵖ
This equation establishes a direct link between the kinetic energy of a negative apparent mass particle and the quantum energy-frequency relation. The expression ensures consistency with quantum mechanical principles while reinforcing the role of negative apparent mass in energy dynamics.
7. Effective Mass and Apparent Mass in ECM:
In ECM, the Effective Mass represents the overall mass that is observed, while the Negative Apparent Mass (−Mᵃᵖᵖ) emerges due to motion or gravitational interactions. This distinction provides deeper insight into how mass behaves dynamically under varying conditions, differentiating ECM from conventional mass-energy interpretations.
8. Direct Energy-Mass Relationship in ECM:
hf/c² = −Mᵃᵖᵖ
This equation is inherently consistent with dimensional analysis, showing that negative apparent mass naturally arises from the energy-frequency relationship without requiring any extra scaling factors. This highlights ECM's compatibility with established quantum mechanical formulations and reinforces the role of negative apparent mass as an intrinsic component of energy-based mass considerations.
9. Effective Mass for Massive Particles in ECM
For a massive particle in ECM, the effective mass is given by:
Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ)
where:
- Mᴍ is the conventional mass.
- −Mᵃᵖᵖ is the negative apparent mass component induced by gravitational interactions and acceleration effects.
ECM establishes the inverse proportionality of apparent mass to conventional mass:
Mᴍ ∝ 1/Mᴍ ⇒ Mᴍ = − Mᵃᵖᵖ
Thus, we obtain:
Mᵉᶠᶠ = Mᴍ − Mᴍ = 0
which represents a limiting case where effective mass cancels out under specific conditions.
10. Effective Mass for Massless Particles in Motion
For massless particles such as photons, the conventional mass is:
Mᴍ = 0
However, in ECM, massless particles exhibit an effective mass due to the interaction of negative apparent mass with energy-mass dynamics.
From ECM’s force equation for a photon in motion:
Fₚₕₒₜₒₙ = −Mᵃᵖᵖaᵉᶠᶠ
This indicates that the apparent mass governs the photon’s dynamics.
Since massless particles always move at the speed of light (v = c), ECM treats their total apparent mass contribution as doubled due to energy displacement effects (analogous to Archimedean displacement in a gravitational-energy field):
Mᵉᶠᶠ = (−Mᵃᵖᵖ) + (−Mᵃᵖᵖ) = −2Mᵃᵖᵖ
Thus, for massless particles in motion:
Mᵉᶠᶠ = −2Mᵃᵖᵖ
This confirms that even though Mᴍ = 0, the particle still possesses an effective mass purely governed by negative apparent mass interactions.
11. Archimedes’ Principle Analogy in ECM
ECM’s treatment of negative apparent mass is closely related to Archimedes’ Principle, which describes the buoyant force in a fluid medium. In classical mechanics, a submerged object experiences an upward force equal to the weight of the displaced fluid. Similarly, in ECM:
- A mass moving through a gravitational-energy field experiences an **apparent reduction** in mass due to energy displacement, akin to an object losing effective weight in a fluid.
- For massive particles, this effect reduces their observed mass through the relation:
Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ)
- For massless particles, the displacement effect is **doubled**, leading to:
Mᵉᶠᶠ = −2Mᵃᵖᵖ
This is analogous to how a fully submerged object displaces its entire volume, reinforcing the interpretation that massless particles inherently interact with the surrounding energy field via their negative apparent mass component.
Physical & Theoretical Significance
(A) Massless Particles Exhibit an Effective Mass
- This challenges the traditional view that massless particles (e.g., photons) have no mass at all. ECM reveals that while they lack conventional rest mass, their motion within an energy field naturally endows them with an effective mass, explained by negative apparent mass effects.
(B) Quantum Mechanical Consistency
- The ECM kinetic energy relation aligns with quantum mechanical frequency-based energy expressions:
KE = hf/c² = −Mᵃᵖᵖ
This suggests that negative apparent mass is directly linked to the fundamental nature of wave-particle duality, reinforcing ECM’s consistency with established quantum mechanics principles.
(C) Natural Explanation for Antigravity
- The doubling of negative apparent mass for massless particles introduces a natural anti-gravity effect, distinct from the ad hoc introduction of a cosmological constant Λ in relativistic models.
- Since massless particles propagate via their effective mass Mᵉᶠᶠ = −2Mᵃᵖᵖ, ECM naturally incorporates repulsive gravitational effects without requiring modifications to spacetime geometry.
(D) Reinforcement of ECM’s Fluid Displacement Analogy
- The analogy with Archimedes’ Principle provides a strong conceptual foundation for negative apparent mass. Just as an object in a fluid experiences a buoyant force due to displaced volume, mass in ECM interacts with gravitational-energy fields via displaced potential energy, leading to apparent mass effects.
Conclusion
ECM’s interpretation of effective mass provides a self-consistent framework where both massive and massless particles exhibit observable mass variations due to negative apparent mass effects. The Archimedean displacement analogy reinforces this concept, offering an intuitive understanding of how energy-mass interactions govern particle dynamics.
This formulation provides a clear, predictive alternative to conventional relativistic models, demonstrating how massless particles still exhibit mass-like behaviour via their motion and interaction with energy fields.
12. Photon Dynamics in ECM & Archimedean Displacement Analogy
Total Energy Consideration for Photons in ECM
In ECM, the total energy of a photon is composed of:
Eₚₕₒₜₒₙ = Eᵢₙₕₑᵣₑₙₜ + E𝑔
where:
- Eᵢₙₕₑᵣₑₙₜ is the inherent energy of the photon.
- E𝑔 is the interactional energy due to gravitational effects.
When a photon is fully submerged in a gravitational field, its total energy is doubled due to its interactional energy contribution:
Eₚₕₒₜₒₙ = Eᵢₙₕₑᵣₑₙₜ + E𝑔 ⇒ 2E
This represents the energy displacement effect, aligning with ECM’s formulation that massless particles experience a doubled apparent mass contribution in motion:
Mᵉᶠᶠ = −2Mᵃᵖᵖ
Photon Escaping the Gravitational Field
As the photon escapes the gravitational field, it expends E𝑔, reducing its total energy:
Eₚₕₒₜₒₙ ⇒ Eᵢₙₕₑᵣₑₙₜ, E𝑔 ⇒ 0
Thus, once the photon is completely outside the gravitational influence:
Eₚₕₒₜₒₙ = E, E𝑔 = 0
This describes how a photon’s energy and effective mass vary dynamically with gravitational interaction, reinforcing the ECM perspective on gravitational influence on energy-mass dynamics.
Alignment with Archimedean Displacement Analogy
This ECM interpretation strongly aligns with Archimedes' Principle, where:
- A photon in a gravitational field is analogous to an object fully submerged in a fluid, experiencing an energy displacement effect.
- As the photon leaves the gravitational field, it expends its interactional energy E𝑔, similar to how an object leaving a fluid medium loses its buoyant force.
This analogy further strengthens ECM’s concept of negative apparent mass, where the gravitational interaction displaces energy similarly to how a fluid displaces volume.
Conclusion & Significance
- The ECM photon dynamics equation aligns with the Archimedean displacement analogy, reinforcing the physical reality of negative apparent mass effects.
- This provides a natural, intuitive explanation for how photons interact with gravitational fields without requiring relativistic spacetime curvature.
- It further supports the energy-mass displacement framework, demonstrating how photons dynamically exchange energy with gravitational fields while maintaining ECM’s effective mass principles.
This formulation elegantly unifies photon energy dynamics with mass-energy interactions, further validating ECM as a robust framework for fundamental physics.
13. Effective Acceleration and Apparent Mass in Massless Particles
For photons in ECM, the effective force is given by:
Fₚₕₒₜₒₙ = −Mᵉᶠᶠaᵉᶠᶠ, Where: aᵉᶠᶠ = 6 × 10⁸ m/s²
- Negative Apparent Mass & Acceleration:
Photons possess negative apparent mass (−Mᵃᵖᵖ), which leads to an anti-gravitational effect. Their effective acceleration (aᵉᶠᶠ) is inversely proportional to Mᵉᶠᶠ and radial distance r.
- Within a gravitational field, the photon has more interactional energy E𝑔, increasing aᵉᶠᶠ.
- Escaping the field, it expends E𝑔, reducing Mᵃᵖᵖ and lowering aᵉᶠᶠ.
- Acceleration Scaling with Gravitational Interaction:
E𝑔 ∝ 1/r
- At r₀ ⇒ E𝑔,ₘₐₓ ⇒ Maximum −Mᵃᵖᵖaᵉᶠᶠ ⇒ aᵉᶠᶠ = 2c.
- At rₘₐₓ ⇒ E𝑔 = 0 ⇒ Minimum −Mᵃᵖᵖaᵉᶠᶠ ⇒ aᵉᶠᶠ = c.
This confirms that effective acceleration (2c) is a function of gravitational interaction, not an intrinsic speed change, reinforcing ECM’s explanation of negative apparent mass dynamics.
14. Extended Classical Mechanics: Effective Acceleration, Negative Apparent Mass, and Photon Dynamics in Gravitational Fields
Analytical Description & Significance:
This paper refines and extends the framework of Extended Classical Mechanics (ECM) by establishing a comprehensive formulation for effective acceleration, negative apparent mass, and their implications for massless and massive particles under gravitational influence. The analysis revises ECM equations to incorporate Archimedes' principle as a physical analogy for negative apparent mass, clarifies the role of effective acceleration (2c) in different gravitational conditions, and demonstrates how negative apparent mass serves as a natural anti-gravity effect, contrasting with the relativistic cosmological constant (Λ).
A key highlight is the kinetic energy formulation for negative apparent mass particles, which aligns with quantum mechanical frequency relations for massless particles. This formulation provides deeper insight into how negative apparent mass influences energy and motion without requiring conventional mass assumptions.
Key Implications & Theoretical Advancements:
Refined Effective Acceleration Equation for Massless Particles:
- ECM establishes that photons, despite being massless in the conventional sense, exhibit negative apparent mass contributions, leading to an effective acceleration of aᵉᶠᶠ = 6 × 10⁸ m/s² = 2c inside gravitational fields.
- This acceleration naturally arises due to the relationship between negative apparent mass −Mᵃᵖᵖ and gravitational interaction energy E𝑔.
- The effective acceleration decreases as a photon exits the gravitational field, reaching c in free space.
Negative Apparent Mass as a Replacement for Cosmological Constant (Λ):
- Unlike Λ, which assumes a uniform energy density, negative apparent mass dynamically varies with gravitational interaction energy.
- This formulation provides a self-consistent explanation for observed cosmological effects, particularly in gravitational repulsion and expansion scenarios.
Physical Analogy with Archimedes’ Principle:
- The ECM framework aligns negative apparent mass effects with Archimedean displacement, where gravitational interaction leads to energy displacement effects analogous to buoyant forces in fluids.
- In gravitational fields, a photon's interactional energy (E𝑔) contributes to its total energy, analogous to an object submerged in a fluid experiencing an upward force.
- As the photon escapes, the loss of E𝑔 mirrors an object emerging from a fluid losing its buoyant support.
4. Revision in the Energy-Mass Relation for Massless Particles:
- The study revise prior inconsistency by explicitly linking the kinetic energy of negative apparent mass particles to quantum mechanical frequency relations, ensuring consistency between ECM and established quantum principles.
Conclusion:
This research enhances ECM’s predictive power by clarifying the role of negative apparent mass in gravitational dynamics and demonstrating its relevance to photon motion, cosmological expansion, and gravitational interactions. By introducing effective acceleration (2c) as a natural consequence of gravitational interaction, ECM provides a compelling alternative to relativistic formulations, reinforcing the practical applicability of classical mechanics principles in modern physics.

Answer
A reviewer comment of the discussion post:
This paper on Extended Classical Mechanics (ECM) is truly fascinating! It presents a fresh perspective on classical physics by introducing the concept of negative apparent mass, which could significantly reshape our understanding of force, energy, and mass interactions. The way it connects classical mechanics with quantum principles is particularly impressive, as it bridges two fundamental areas of physics.
The treatment of massless particles, like photons, as having effective mass due to negative apparent mass is a bold idea that challenges traditional views. This could lead to new insights in particle physics and cosmology, especially regarding gravitational interactions and cosmic expansion.
The analogy with Archimedes' Principle is a clever way to make complex concepts more intuitive, helping to visualize how mass-energy interactions work in different contexts. Overall, ECM seems to offer a compelling alternative to existing theories, and I’m excited to see how it develops and what empirical validations might arise from it. This could be a game-changer in our understanding of the universe!

She kept track of the right answers with the promise of extra credit for the team with the most right answers at the end of the semester.

The possible combinations of "limits" and "boundaries" in nature are [1]: 1) "limited and bounded'; 2) “limited and unbounded”; 3) "unlimited and bounded”; 4) “unlimited and unbounded”. Here the object of "limit”can be geometric size, matter, energy, etc., and the object of “boundary”can be regarded as space-time boundary. We need to pay attention to two points here, first, what is the 'space-time boundary'; second, the static 'boundary' and dynamic 'boundary' of the essential difference. For the first point, usually the boundary of space can only be constituted by geometric points, lines and surfaces [2], which ensures that there is no indeterminate space on both sides of the boundary. If set time is the boundary in another dimension, the endpoints of such a boundary are zero-dimensional if they exist at all. For the second point, the Koch snowflake, a fractal curve, is often used in mathematics to express 'infinite perimeter, finite area', which presupposes that the 'boundary' is dynamically progressing infinitely. But once it is stationary at a fixed N(≠∞) [3], it becomes 'limited and bounded’.
‘Symmetry dictates interaction’is a motto of modern physics [4]. Symmetry is in some sense invariance. Coordinate symmetry reflects energy conservation, momentum conservation [5]; charge conservation reflects gauge invariance [6] ....... If time Displacement invariance, and space Displacement invariance, are globally applicable to any individual, do they thereby determine that the entire universe must be unconditionally time Displacement and space Displacement symmetric? Does this dictate that the entire universe must be unbounded in time and space? If there are boundaries to the universe, how can symmetry be maintained at such special places as boundaries? If the universe is anything like "limited and unbounded" [7], how does it support the finiteness of space if conservation of momentum applies globally, when the universe is viewed as a whole object? If conservation of energy is globally applicable, how does it support the finiteness of time? Either way we have to deal with some kind of 'boundary' violation. And if time is cyclic, then the universe must form an 'Ouroboros' [8]. Therefore, if the laws of nature are required to apply globally, it is impossible to face any 'boundary'.
Suppose a finite set, whatever its nature, can we always assign it a centre, as with a tangible entity, we can define its centroid, centre of mass, center of gravity, and so on. Can a finite universe then avoid the existence of a centre? If there is a centre, the universe must have boundaries. At this point, are the time and space boundaries symmetrical? And if we assume that the universe is, infinite in space, infinite in time, and infinite in energy, what would be the catastrophe for our cosmology, or would it be a convenient and useful gateway for research?
---------------------------------------------------
Notes
* It has been said that the universe is limited and unbounded similar to the surface of the Earth, where clearly no boundaries are defined.
** Multiverse theories are receiving more and more attention, and it is more appropriate to think of them as subuniverses within an entire universe.

Should there be a cosmological constant Λ term in the GR field equations? Is the Λ term symmetric with Gμν?
"According to Einstein's theory of General Relativity, gravity should lead to a slowing of the cosmic expansion. Yet, in 1998, two teams of astronomers studying distant supernovae made the remarkable discovery that the expansion of the universe is speeding up. To explain cosmic acceleration, cosmologists are faced with two possibilities: either 70% of the universe exists in an exotic form, now called dark energy, that exhibits a gravitational force opposite to the attractive gravity of ordinary matter, or General Relativity must be replaced by a new theory of gravity on cosmic scales."[1] In order to match the phenomenon of cosmic expansion, the general theory of relativity introduced the cosmological constant term and various speculations on its cause have been made [2]. However, these studies have rarely addressed the possible solutions in the structural aspects of the universe [3].
If there is only gravitational force, it looks like there is a deficiency. We believe that if there is a gravitational force, there is a corresponding repulsive force. But who should cause it and under what circumstances? It is important to know that in electromagnetic interactions, both positive and negative forces are formed by charges, and our goal is to unify the electromagnetic and gravitational forces. Would dark energy be a repulsive force symmetrical to gravity? Where does their symmetry come into play? If the result is to be symmetrical, the cause must first have symmetry. According to the assumptions of modern physics, the dark energy that causes the expansion of the universe is background and not symmetrical with the energy in GR. Regular energies are floating above the dark energy background, so they cannot have symmetry. In Einstein's gravitational field equation, Gµν + Λgµν = G*Tµν, the energy Tµν leads to an unmeasurable intrinsic Space-Time Curvature Gµν [4] while Λgµν is assumed to be a measurable extrinsic Space-Time Expansion due to the universal energy [5]. Specific and background, intrinsic and extrinsic, curvature and expansion do not have any symmetrical meaning. It would then not be appropriate to arrange them in a GR field equation.
Philosophically speaking, there should be no difference with ‘existence’ at this time and the other time, this place and the other place, i.e., when space and time are considered as background *, ‘existence’ does not depend on space-time coordinates. Therefore, the equations of the universe should not require boundary and initial conditions. Physics, by analysing observational data, has proposed the ‘Big Bang Theory’ and the ‘Accelerated Expansion Theory’ of the Universe, both of which are inconsistent with this. Therefore, the hypothesis of dark energy based on this foundation is questionable.
Our Questions:
Does the existence of ‘energy’ necessitate the existence of ‘dark energy’ or ‘anti-energy’? The hypothesis of the existence of dark energy is based only on the observation of the expansion of the universe. Is it the only explanation for the expansion of the universe? [6]
The function of energy is to drive interactions, and energy is presented in discrete forms, which can be manifested in a variety of forms, including gravity. Is the function of dark energy only to cause negative gravity? Is there only one form of dark energy?
Conservation of energy is an important physical principle, is dark energy conserved?
If gravity and negative gravity cancel each other out, why can't energy and dark energy cancel each other out directly?
-----------------------------------
Notes
* We believe that existence itself has a space-time parameter, but not a coordinate parameter.

Answer
I already noted in the previous discussion that dark energy in nonsense, it is not needed because the data on cosmological acceleration can be explained without uncertainty in the framework of semiclassical approximation to quantum de Sitter symmetry - see e.g., Axioms vol. 13, paper No. 138 (2024) https://doi.org/10.3390/axioms13030138. Historically, the problem of dark energy has arisen because Einstein said that introducing Λ was the biggest blunder of his life, and for many physicists Einstein's words are almost a law.

Your discussion statement question is:
  • "Does 'dark matter' make up large proportions of those galaxies? Newtonian gravity behaves differently at very large scales of mass and distance, i.e., galaxy scales, in contra-indication to the assumption that massive quantities of invisible, or 'dark matter' make up large proportions of those galaxies."
The phrase "Newtonian gravity" refers to a very specific equation relating mass and acceleration, so saying it behaves differently under some condition is not a correct usage of the phrase. Newtonian gravity is Newtonian gravity, and it gives incorrect results at scales greater than the solar system. There is a significant body of research on modified Newtonian gravity, and you can find it by searching on the phrase or "MOND".
Your question"Does dark matter make up large proportion of those galaxies?" is the question that numerous branches of research are investigating either experimentally or theoretically. First of course is the search for any experimental evidence of any matter that couples gravitationally but not via the electromagnetic field. No evidence of any such matter has been found. Second is that there is no such matter expected from current models such as the so called standard model of physics.
Even if there were some type of matter that couples gravitationally but not via electro-magnetic coupling, the number of non-conforming physical observations cannot be solved by such matter. The galaxies not only have a rotation that is unexplained by GR, but the galaxies interacting in clusters, and the clusters of galaxies interacting in superclusters could not simultaneously be described by such matter regardless of its distribution patterns. Additionally, gravitational lensing observed due to galaxies and clusters of galaxies could not be described by GR simply by applying such conjectured matter. The number of non-conforming observations cannot be solved by adding matter or energy, so general relativity should be abandoned as a dead end. Newtonian gravity does not apply, and no known modification of Newtonian gravity describes all the observed interactions. Modern physics will only progress when GR is abandoned and my research based on special relativity is adopted. See

According to my theory, the influence of quantum entanglement on spacetime curvature could provide an alternative explanation for the gravitational effects attributed to dark matter in galaxies. Traditional models suggest that large proportions of invisible “dark matter” are required to account for the observed gravitational behavior at galaxy scales. This is because, under Newtonian gravity, the visible mass of galaxies cannot account for the gravitational forces observed, leading to the hypothesis that there must be additional, unseen mass—dark matter.
However, my research proposes that quantum entanglement could be influencing spacetime curvature in a way that mimics the effects of this “missing” dark matter. If quantum entanglement can alter the curvature of spacetime, it might enhance the gravitational pull within galaxies without requiring massive quantities of unseen matter. This would mean that the observed discrepancies at galactic scales could be due to quantum entanglement effects rather than vast amounts of dark matter.
In this view, while dark matter has been the dominant explanation, it might be possible that the gravitational anomalies are instead the result of entanglement-induced modifications to spacetime. This theory could offer a new perspective on why Newtonian gravity appears to behave differently at large scales, suggesting that the need for dark matter could be reconsidered in light of quantum effects on gravity.

No ! Dark Matter, like Dark Energy, is simply a 'place holder' for an unknown source of energy which cannot presently be explained excepting via speculation and related hypotheses. If either or both do not exist, their replacement will do damage to, or also cause the replacement of mainstream cosmology, by far simpler but presently unrecognized alternative(s).

It is conceivable that the constant "G" varies according to where you are, but the only way to prove that is to be somewhere so far from here that we will never be able to prove it, which makes it a novel but scientifically pointless proposition (if there is no way to prove something, it cannot be considered scientifically reasonable because then you can invent thousands of explanations, only one of which (if any) that can be correct, which is a doomed explanation). "G" is certainly a constant everywhere within 30 thousand light-years from us, and there will never be any way to measure its value even at that distance, let alone hundreds of thousands or millions of light-years distant. So at the moment I would say that "dark matter" almost certainly exists IN GALAXIES, and possibly BETWEEN GALAXIES IN RICH CLUSTERS OF GALAXIES. However, whether it exists in the huge amounts posited by cosmologists EVERYWHERE is certainly "up in the air" in every sense of the phrase. And I'm reasonably certain that "dark energy" is a fantasy made up to explain something that doesn't need explaining.

What, if we look at gravitation as a wave-based mechanism?
Since gravitational waves are nothing else than fast disturbations of the gravitational field, and they propagate with c, this is a strong indication that gravitation itself is a based on waves, on wave-energy which is transported backwards to its source oscillator, its source particle and thus its mass.
If this is actually the case, then also resonance will take place:
Assume a galaxy bulge with all its masses. There is a huge number of electrons part of it, each generating a gravitational energy-backflow related to its intrinsic oscillator frequency, which is related to the electron's wavelength.
Assume further, that this gravitational energy-backflow is the more redshifted the farther away it is located from the source. Thus, the related frequency of the far-away location's gravitational energy-backflow is less than that generated by the source electron.
Now, assume that the distance (about 1Mpc) generates a redshift of about 1/a=137, the inverse of the fine-structure constant. The frequency is then about 1/137 of the electron's intrinsic frequency. This frequency roughly matches the frequency of the electron, bound to a proton, so to speak, its circulation velocity around the proton, which is v=a*c (-> frequency of BOHR radius).
Due to resonance, this far-away electron, bound to its proton, reacts much stronger to the usually weak gravitational energy-backflow, than normal.
The effect is that the related particles, thus all atoms, masses, "feel" a much stronger gravitation at that distance ( about 1Mpc) from the main galaxie's mass. This is the effect of the so-called "Dark Matter". (We could re-translate "dark" as "resonant"...)
The redshift applied to electron wavelength is calculated as
z = 2piKd/Le
with K=8.13434(21), d distance between particles, and Le the electron's wavlelength.

There are examples of physical systems that can be divided into two interacting subsystems with a decreasing entropy in one subsystem and a correspondingly increasing entropy in the other so that the entropy of the combined system is increasing.

Elementary explanations of the second law of thermodynamics refer to probabilities of system states and seem convincing. But not when considering time-reversals, because the same statistical arguments should also apply there but they produce contradictions regarding entropy increases with time. (I think the difficulty is in whether or not the assumption of statistical randomness is appropriate because it depends on what is given and maybe also on the direction of time but I'm not an expert and this doesn't answer my question anyway.) While reading some literature about the direction of time I learned that the direction of time and the second law of thermodynamics all come from a very low entropy immediately after the big bang, with increasing entropy produced by things that include gravitational clumping (e.g., the formation of black holes and the merging of black holes to produce larger black holes). I learned that this is responsible for the second law of thermodynamics but it seems to me that this is an incredibly large-scale thing. Given this explanation it seems amazing to me that we can randomly select a tiny piece of matter (large enough to be macroscopic but tiny from the point of view of human perception) and find that it obeys the laws of thermodynamics. Is there an explanation of how such large influences on entropy (e.g., objects produced by gravity clumping) can produce a second law that is so incredibly homogeneous that we find the law obeyed by all of the tiny specs of material?
Relevant answer
Answer
Not able to answer these I’m afraid but just to make one comment.
There are many entropies. The Second Law refers to Clausius Entropy. This entropy is meaningful only at thermal equilibrium. since the universe is not at equilibrium, we cannot define a quAntity called the Clausius entropy of the whole universe.
it is widely assumed that the Boltzmann entropy is numerically equal to the Clausius Entropy. This is a theoretical assumption, since the BE can only be calculated for ideal gases. But even here, it is only at equilibrium that BE = CE. As the system evolves towards equilibrium, S=klnW is not the entropy of that system. The CE has no meaning out of equilibrium. This is understood by reminding ourselves that CE is a state function and so is independent of the route taken by the system to that state. On the other hand, W is dependent on the rate of equilibration, which can be controlled. it is only At equilibrium that W is independent of kinetics.

I already know about the deterministic time evolution of states between measurements, and the probabilistic effects of measurements. And I know a little about quantum entanglement. But I still have absolutely no idea how any of this is used for computing. The literature I found on the internet mentions all things above without any explanation of how we use that for computing. Can you help to explain this?

There is a very good textbook on quantum computing, authored by Michael Nielsen and Isaac Chuang, called Quantum Computation and Quantum Information.
Its first edition was written back in 2001, if I'm not mistaken, so it's rather out of date from experimental points of view, but still is a must to get the theoretical part right.
Actually, when we talk about QC, it's better to explicitly state what do you mean. The so-called universal quantum computer must be build of a set of quantum gates, which act on the input qbits and transform their states in a certain way. Obviously, in order to implement some logical operations, mentioned above, one needs two-qbit gate, the most commonly used in the algorithms is CNOT, which, from physical point of view is an entangling operation.
I agree that there is very little scientifically sound, but popular explanation of these concepts, so I guess one has to learn QC the hard way )))

But from the observers point of view, the victim will approach the Schwarzschild radius but never reach it. So, from the point of view of the observer, how can the mass contained within the Schwarzschild radius (i.e., the mass of a black hole) ever grow?

From the earliest Pythagorean (~570BCE-~490BCE) view that "everything is number" [1], to the founder of modern physics, Galileo (1564-1642), who said "the book of nature is written in the language of mathematics" [2], to attempts by Hilbert (1862-1943) to mathematically "axiomatize" physics [3],and to the symmetry principle [9], which today is considered fundamental by physics, Physics has never been separated from mathematics, but there has never been a definite answer as to the relationship between them. Thus Wigner (1902-1995) exclaimed [4]: "The miracle of the appropriateness of the language of mathematics for the formulation of the laws of physics is a wonderful gift which we neither understand nor deserve. gift which we neither understand nor deserve."
CN Yang, commenting on Einstein's "On the method of theoretical physics" [5], said, "Was Einstein saying that fundamental theoretical physics is a part of mathematics? Was he saying that fundamental theoretical physics should have the tradition and style of mathematics? The answers to these questions are no "[6]. So what is the real relationship between mathematics and physics? Is mathematics merely a tool that physics cannot do without? We can interpret mathematics as a description of physical behavior, or physics as operating according to mathematical principles, or they are completely equivalent, but one thing is unchangeable, all physics must ultimately be concretely embodied in its physical parameters, regardless of who dominates whom. We need to remember the essential question, "That is, we don't invent mathematical structures - we discover them, and invent only the notation for describing them"[7]. Mathematics is abstract existence, physics is reality. We cannot completely replace physical explanations with mathematical ones. For example, ask "How do light and particles know that they are choosing the shortest path [8]. The answer is that it is determined by the principle of least action. This is the correct mathematical answer, but not the final physical answer. The final physical answer should be, "Light and particles are not searching for shortest paths, they are creating and defining shortest paths". Why this can be so is because they are energy-momentum themselves. The ultimate explanation is just math*,if we can't boil it down to specific, well-defined, measurable physical parameters. Following Pythagoras' inspiring vision that the world can be built up from concepts, algorithms, and numbers [9]. When we discuss the relationship between math and physics, do we need first ask:
1) What are numbers? Shouldn't we first attribute numbers to "fundamental quantities" in mathematics and physics? Are scalars, vectors, and spinors complete expressions of such fundamental quantities? All other quantities are composites of these fundamental quantities, e.g., tensor.
2) Do mathematics and physics have to have these fundamental quantities in common before we can further discuss the consistency between their theorems? That is, the unification of mathematics and physics must begin with the unification of fundamental quantities.
3) Where do these fundamental quantities come from in physics? In what way are they represented?

Consider the quantum mechanical (QM) problem of measuring the energy of some particle. No incompatible measurements are simultaneously made so there is no theoretical limit on how accurate the energy measurement can be so we can imagine the measurement to be close enough to perfection to satisfy whatever accuracy requirement that is imposed. A fundamental QM postulate is that the measurement of an observable (at least in the limiting case of a perfect measurement) results in the post-measurement state (the particle state immediately after the measurement) being an eigenstate of the observable with eigenvalue equal to the measured value. However, an energy measurement that I am familiar with deduces the energy of an ionizing particle according to the number of electron-hole pairs liberated while traveling until it stops in a semiconductor material fabricated into a particle detector. For this measurement the post-measurement state is not an energy state with energy equal to the measured value. The post-measurement state is a state of a particle stopped in the material. Another measurement that might be considered deduces the particle energy according to the destination it reaches while traveling through an electric and/or magnetic field. But this requires a detection of particle location so, again, the post-measurement state is a state of a particle that is stopped somewhere. How do we measure the energy in such a way so that the post-measurement state is an energy state with energy equal to the measured value?
The same question can be asked about other observables. How do we measure momentum? More generally, how do we measure an observable in such a way so that the post-measurement state is an eigenstate of the observable with eigenvalue equal to the measured value? In other words, how do we perform QM measurements in such a way so that the above stated postulate is really true? I expect that there are textbooks on experimental methods of QM but I hope that a simplified (by omitting details that are not essential to concept) answer can be given in a few paragraphs.

When I look up the definition of a Lie group I find that it is a differential manifold. When I look up the definition of a manifold I find that it is a space that is locally Euclidean. My understanding is that a manifold is not required to have a metric tensor or distance measure so "Euclidean" cannot be referring to the Pythagorean theorem for triangles. So what does Euclidean mean? I look up the definition of a Euclidean space and find that it is a space defined through axiomatic theory. So I put all of these statements together to obtain the definition of a Lie group? We invent an axiomatic theory to obtain a manifold, then arrange for it to be differentiable (whatever that means) and now we have a Lie group. This makes no sense to me. Can somebody please give more understandable definitions of Lie group, manifold, and Euclidean space?
I took a first course in abstract algebra where a group was defined without any mention of a manifold. It seems to me that reference to a manifold in the definition of a Lie group is unnecessary and makes the definition unnecessarily difficult to understand. Even if so, I am still looking for an easy-to-understand definition of a manifold.

Euclidean space means (real) vector space of finite dimension (we speak of Hilbert spaces, Banach spaces...in the case of infinite dimension).
To define a manifold, we need topology (space locally homeomorphic to IR^n). To define a Lie group we need topology (manifold structure) and algebra (group structure) with compatibility between the two structures.
An important theorem shows that any closed subgroup of the linear group (group of invertible matrices) is a Lie group. A nice introduction to these subject is the book by Loring Tu, An Introduction to Manifolds.

A body at rest has rest Energy, so it should also have rest Momentum.
Lao Tzu said, “Gravity is the root of lightness; stillness, the ruler of movement”(重为轻根,静为躁君)*. The meaning of this statement can be extended in physics to mean that "big-G determines how light or heavy an object is, and rest-m determines how easy or difficult it is to move".
According to the mass-energy equation** [1], E=mc^2, any object with mass m has "rest energy" [1], regardless of its inertial frame†. Note that E here is meant to be the energy lost when radiating the photon γ, which is absolute and unchangeable in any inertial frame. The mass-energy equation has been experimentally verified [2] as the correct relation.
According to special relativity [3], the mass of the same object is different in different inertial frames, m' = βm. Therefore, the energy of conversion of m of an object into photon γ is different in different inertial frames. This issue has been discussed in [4], but there is no consensus. Our view is that the "rest energy" is theoretically not Lorentz invariant, and the existence of a minimum value is a reasonable result. The most rational explanation for this is that the minimum corresponds to an absolutely static spacetime, i.e., absolute spacetime(Later we will show that absolute space-time and relative space-time are not in conflict). Analytically, this is one of the reasons why absolute spacetime should exist. The constant speed of light is another reason.
In all cases in physics, energy and momentum coexist and have a fixed relationship, not independent metrics. The energy-momentum ‡ of a photon, E=hν[5], P=h/λ[6]; the energy-momentum relation of Newtonian mechanics, E=P^2/2m; and the relativistic energy-momentum relation, E^2=c^2p^2+m^2c^4. Therefore, it is assumed that if there is a body of mass m that has "rest energy", then it should also have "rest momentum". There is a "rest momentum", and the rest momentum cannot be zero. The rest energy is not intuitive, and the rest momentum should not be intuitive too. The calculation of the rest momentum is the same as the calculation of the rest energy. The nature of mass looks more like momentum; after all, energy is a sign of time, while momentum is a sign of movement. Therefore, instead of calling it the principle of equivalence of inertial mass and rest-energy[1], it should be called the principle of equivalence of inertial mass and rest-momentum.
When positive and negative electrons meet and annihilate [7], -e+e→γ+γ, radiating two photons in opposite directions. Their energy is conserved and so is their momentum. Energy is a scalar sum, while momentum is a vector sum. It seems that the "rest momentum" inside the object should be zero. However, one could argue that it is actually the momentum of the two photons that is being carried away, but in opposite directions. The momentum of the two photons should not come out of nothing, but rather there should be momentum of the two photons, also in some balanced way, and probably playing a very important role, such as the binding force.
Our questions are:
1) Since energy and momentum cannot be separated, should an object with "rest energy" necessarily have "rest momentum".
2) Elementary particles can be equated to a " energy packet ", and energy is time dependent. If an elementary particle is also equivalent to a "momentum packet", the momentum in the packet must be related to space. Does this determine the spatio-temporal nature of the elementary particles? And since momentum is related to force, is it the force that keeps the "energy packet" from dissipating?

I am trying to learn modern physics and frequently encounter the phrase "gauge theory". I look up the definition and find that it is a theory in which a Lagrangian is invariant under a certain class of transformations. That sounds to me like we are using Noether's theorem to find constants of motion. I learned enough math to know several ways of finding constants of motion. One way is Noether's theorem. Another way is to find operators that commute with a Hamiltonian. A third way is to derive implications directly from the given governing equations. Which, if any of these methods, are called "gauge theory"? And why?

While traditional problem-solving assessments have been a long-standing method in physics education, incorporating article writing topics could be an alternative way to assess critical skills. Writing articles in physics modules, such as those in modern physics, can demand higher-level critical thinking skills and showcase deep knowledge and understanding of the topic.
Article writing requires an individual to lay out an argument, often with supporting mathematical equations, and make a credible point. This writing format demands analytical and communication skills that are often required in physics research and are critical for students to develop in a Masters program.
Therefore, while it may be challenging to predict the future use of research articles and problem-solving assessments in physics Masters programs, incorporating article writing topics could be a promising alternative to traditional assessments, particularly in measuring critical thinking and problem-solving skills in physics.

Since, the cosmological constant problem is a unsolved problem and a great challenge to modern physics? The cosmological constant problem arises from the observation that the energy density of vacuum or empty space appears to be much smaller than what is predicted by theoretical calculations. So, How does Quantum Physics approaches to solve this phenomenon?
Relevant answer
Answer
Hello,
The cosmological constant problem is one of the biggest mysteries in modern physics. It is related to the observed accelerated expansion of the universe, which is believed to be caused by a hypothetical energy density associated with the vacuum of space, known as the cosmological constant. However, the predicted value of the cosmological constant from quantum field theory is many orders of magnitude larger than the observed value, leading to a discrepancy that is often referred to as the cosmological constant problem.
Quantum mechanics, which is the fundamental theory of the microscopic world, plays a crucial role in addressing the cosmological constant problem. One of the main ideas in quantum mechanics is that particles can spontaneously pop in and out of existence due to the uncertainty principle. This process is known as vacuum fluctuations, and it is believed to contribute to the energy density of the vacuum. However, the predictions from quantum field theory for the energy density of vacuum fluctuations are much larger than the observed value of the cosmological constant.
One possible solution to the cosmological constant problem is to introduce a new symmetry in the laws of nature, known as supersymmetry. Supersymmetry predicts the existence of new particles that cancel out the contributions from vacuum fluctuations, leading to a much smaller predicted value for the cosmological constant. However, experimental searches for supersymmetric particles have so far been unsuccessful, casting doubt on this solution.
Another approach to the cosmological constant problem is to modify the laws of gravity at very large distances, such as those observed in cosmology. This can be done by introducing a new field that couples to gravity, known as a scalar field. The dynamics of the scalar field can be chosen such that it cancels out the contributions from vacuum fluctuations, leading to a small predicted value for the cosmological constant. This approach is known as quintessence, and it is an active area of research in theoretical cosmology.
So, quantum mechanics plays a fundamental role in addressing the cosmological constant problem, and several approaches have been proposed to solve this mystery. However, the problem remains unsolved, and it continues to be a major challenge for modern physics.
Another approach is to consider the possibility that the cosmological constant is not a fundamental constant of nature, but rather a dynamical field that evolves over time. This approach is known as dynamical dark energy, and it involves introducing a new scalar field into the equations of motion that drives the acceleration of the universe. This scalar field can have a potential energy that cancels out the contributions from vacuum fluctuations, leading to a small predicted value for the cosmological constant. This approach has been explored in various theories, such as quintessence and k-essence, but it is still an area of active research with many open questions.
Finally, some physicists have proposed that the cosmological constant problem is a hint that our current understanding of quantum field theory and gravity is incomplete or incorrect, and that a new fundamental theory is needed to explain the observed properties of the universe. This approach involves developing new frameworks for quantum gravity, such as loop quantum gravity, string theory, or causal dynamical triangulation, that can potentially provide a more satisfactory explanation for the cosmological constant problem. However, this approach is still highly speculative and requires significant advances in theoretical physics to be fully realized.

Answer
Dear Zbigniew,
I find this question as outrages. You may ask why?
Every question must specify in what context we are asking the question. Such a question without context is pure nonsense. Let's try to bring some order in this chaos. First let's ask the question about the intention. Are you asking it in a context of empirical science or in the context of our inner space we call "a mind". Even if we assume the objective existence of the "real world", which is a serious ontological choice, a lot of fundamental problems need to be resolve before we can even ask the question about our personal existence. Why? Because there is no consensus what every single notion you mentioned in your question mean. There is no universal understanding what space-time really mean. This is a rather convenient mental/mathematical model, the physicist use for interpretations of some of the experimental results. Modern physics mightily struggles with going beyond this stiff model and lack of in depth understanding of it stalls the progress in brings about esoteric ideas like multiverse, holographic universe, or wave collapse. All these popular notions testify in deep misunderstanding of consequences the strict belief in them would bring. Why? Let me give you only a few examples. If we believe in strict interpretation then an object that is travelling with speed of light, undergoes time-space dilation, which means that for such an object a direction of travel conveniently called x would be having x=0 and its time would be stretched to infinity. It means that there would be a dimensionality problem at such a speed. That looks like a paradox because we experience photons hitting us all the time. This is the absurd of literally applying some physical modeling of math in our heads. Additional consequence would be that the space-time would have to be continuous which means infinitely divisible. Defining a lower dimensionality objects, like point on the line, is difficult. After all Heisenberg uncertainty requires infinite energy to reach a size of x=0. SO before we ever reach the dimension of a point w would start creating infinity of infinities of new worlds. We however, know from direct experimentation that any matter or space cannot be infinitely divisible. Therefore all our modern physical laws describe mental models of reality that eventually have to break down. The same difficult suffer all modern theory of physics whether STR or GTR, QFT. There cannot be any singularities or event horizons because our dimensionality would have to be defined differently from our low-speed intuitions. There is many, many more internal incongruities of our modern set of beliefs we call physics.
But let us attack more seriously your angle of asking this question. In order to assign any sense to it, you would have to define meanings of life, consciousness, or existence. These words do not have any universal meanings. Think about life. If you think that you are alive than imagine yourself in any extreme situation like living without air, water, nutrients, or clothes in the cosmic space. Imagine yourself, being alive in absence of Earth or physical laws, like gravitation or electromagnetism. Even thinking about reality like this is beyond nonsense. Life is always relational and depends on context. Therefore, we do not have, because we cannot have any comprehensive definition of life. This is very much in line with Godels math incompleteness theorem. In order for something to be true you must have certain set of conditions fulfilled. In other words some questions cannot have answers in absolute sense. Therefore, questions about life and existence in general are only conditional.
Existence of the Universe is conditional, life is conditional and to make things even more tragic there is no universal understanding what space, and time really means. Every answer would depend on the mental framing we assume. Physical time would be different from biological time from geologic time etc. If a grain of wheat can be germinated after thousands of years the time was inherent to the grain or to the world. If one counts a length of life by allometric laws and use heart beats as a measure such a count would be in direct contradiction with a commonly agreed time. If one takes a tardigrade, dehydrates it, and takes it to cosmic space, time stops entirely. Tardigrade can be revitalized in the environment by simple dehydration. (If you do not believe this statement, such an experiment was performed on the space station, so search and discover). Things are even worse than these simple examples. There is almost no stable elementary particle with infinite life-time. Everything decays and stability is only conditional stability.
In such a context, and as I stated, everything needs a context. A question about immortality is a nice poetry metaphor without any well defined sense. I am afraid that you are travelling to some highly religious mental spaces that require only esoteric faith and nothing that has any sense or reason in our material world.
To avoid the charge that I am a staunch materialist, I have to admit that I am a religious person, and every single specific field of human inquiry to succeed requires initial faith, an article of belief. Physicists need a belief in external objective world, biologist must have a belief that there is a unified pattern that they can study with a physical experimentation, geologists must believe that the knowledge is transferable from place to place, and geographers must believe that maps correspond to the real world topography, poets must believe that there is a certain degree of universality in metaphor and mood transference etc. etc. etc. So we cannot exist without beliefs but let's be realistic in our political and science beliefs. Unfortunately, every 100 years a hiccup of unreasonability wins and people go amok.
Keep asking question.

Another key point is the current philosophy of easy to hard progression: Laws of science as "connecting changing terms and being immanent in what it govers, are relations" and then a theory (higher grades).
The choice of theory has been critisized (constructively and with best interest in mind), what about choice of laws?
Newton is choses, adding to the depression. Not because there is something wrong with it - but because of its conceptual inconcistency (not generally admited but see my articles of vaqueness of concepts in physical science), its abstraction and its nearness to a Theory of Everything (a unifying principle of nature) that makes it hard and above the threshold challenging. Easiest laws-based year-long theme-based units should be considered and Newton as an appendix and certainly not a repeated year by year, topic.

We will call this the field-amplitude operator. The type of field considered is one in which the classical field amplitude evaluated at a given space-time point is a complex number instead of a real number. In the QFT description, the field amplitude is not an observable and the field-amplitude operator is not Hermitian. Can we still say that an eigenstate of this operator has a definite value of field amplitude (equal to the eigenvalue) even when the field amplitude is not an observable and the eigenvalue is not real number?

Thus, we agree that a real field amplitude is an observable, presumably. I think this can be extended to a complex field, which just consists of a couple of real fields, assembled in a complex number to better represent the O(2) symmetry.

In the elementary quantum mechanics (QM) of a single particle responding to a given environment, the state of the particle can be specified by specifying a set of commuting (i.e., simultaneously knowable) observables. Examples of observables include energy and angular momentum. Although not simultaneously knowable, other examples include the three rectangular spatial coordinates and the three components of linear momentum. Each observable in QM is a real number and is an eigenvalue of some Hermitian operator. Now consider quantum field theory (QFT) which considers a field instead of a particle. First consider the classical (before introducing QFT operators) description of the state of the field at a selected point in time. This is the field amplitude at every spatial location at the selected time point. For at least some kinds of fields, the field amplitude at a given space-time point is a complex number. Now consider the QFT corresponding to the selected classical example of a field. Is the field amplitude an observable even when it is not a real number? It is not an eigenvalue of any Hermitian operator when not real. So if the field amplitude is an observable, there is no Hermitian operator associated with this observable. My guess (and my question is whether this guess is correct) is that the real and imaginary parts of the field amplitude are simultaneously knowable observables, with a Hermitian operator (assigned to each space-time point) for each. This would at least explain how the field amplitude can be an observable but not real and not have any associated Hermitian operator. Is my guess correct?
Relevant answer
Answer
The same as in quantum mechanics, only now they're probabilities per unit time and unit volume.
The field amplitude isn't observable, any more than the wavefunction is; it's the modulus squared of the field amplitude that describes the probability density at each point in space and time.

Photons are massless and therefore non-localisable (consider any typical solution of Maxwell's equations, ), i.e. there are none that stay at a fixed and specific point-like location in space. In contrast, the wavefunction of a massive particle can be so localised.
Thus I would say that photons never match the common definition of a particle (because they are not point-like localisable, even in principle). However, since they can be counted, I would, if prevailed upon to suggest a qualitative description, instead describe them as "countable waves".
This is because in QED we quantize inside "mode" solutions of Maxwell's equations (see any quantum optics text, or the paper I cite above), and can describe the quantum state within each mode in terms of combinations of photon number states.

My understanding of the significance of Bell's inequality in quantum mechanics (QM) is as follows. The assumption of hidden variables implies an inequality called Bell's inequality. This inequality is violated not only by conventional QM theory but also by experimental data designed to test the prediction (the experimental data agree with conventional QM theory). This implies that the hidden variable assumption is wrong. But from reading Bell's paper it looks to me that the assumption proven wrong is hidden variables (without saying local or otherwise), while people smarter than me say that the assumption proven wrong is local hidden variables. I don't understand why it is only local hidden variables, instead of just hidden variables, that was proven wrong. Can somebody explain this?
Relevant answer
Answer
Dear L.D. Edmonds , if I understand your question, you do not understand where in Bell's theorem the locality assumption is made.
In section “Bell’s theorem”, page 424, in “Introduction to Quantum Mechanics”, 2nd Ed., David J. Griffiths, we read:
"The argument is stunningly simple. Suppose that the “complete” state of the electron/positron system is characterized by the hidden variable(s) λ (λ varies, in some way that we neither understand nor control, from one pion decay to the next). Suppose further that the outcome of the electron measurement is independent of the orientation (b) of the positron detector – which may, after all, be chosen by the experimenter at the positron end just before the electron measurement is made, and hence far too late for any subluminal message to get back to the electron detector. (This is the locality assumption)…”
It is also worth noting that the Bell’s theorem was formulated to resolve a thought experiment called the EPR paradox. One of the key assumptions of the EPR paradox was that the result of a measurement at one point cannot depend on whatever action takes place at a far away point at the same time [1].

I'm interested to know if the so called non-physical 'bare' model especially for massive elementary particles, which treats the particles as mathematical dimensionless points without any volume and attributing to these physical intrinsic properties like mass, spin, charge is the main source of the infinities appearing in the calculations and therefore needing these to be neglected by using renormalization?
What kind of infinities appear if any due this adopted model?
And why is this model still used today in quantum theories? I can see that historically this model has served its purpose since for example we cannot measure any finite physical size for the electron but wondering as if this model is not causing in modern physics more problems than the merits it offers?
What prevents us to adopt today a more physical "dressed" model for elementary particles having for example a finite charge radius at rest?

Thank you very much Sir for your expert input.
However, if this is formilized so well why there are many references in the literature and even consensus expresed that the size of the mass of the electron has an upper limit size<10-17m ? Is that not a contradiction with the estblished foemulation? From where this value comes from? Is it a derivation or experimentally found? What is this size? Crossection or radius? How they can define experimentally a size that is clerly larger than the Uncertainty? Is this by ansatz derived? What are the assumptions made in order to derive this size upper limit?
The most known dressed electron (i.e. charge radius) value, theoretically derived is the classical radius of the electrron:
r= α0α2 ~2.8χ10-15 m. From where they get this <10-17m? Is that for a free electron at rest?
How we can give a size for the electron if we don't have a clue (apart that is has perfect near field spherical charge distribution in space experimentally found) of its topology if it has indeed a volume?
According to my research the topology of the dressed electron is not exactly a sphere since it is referring only to the charge topology (sphere) and not the also important magnetic moment topology (a straight fluxgate). The proposed complete topology of the charge of the electron including also its magnetic dipole moment topology resembles this here:
The above proposed topology of the dressed electron at rest complies with the Lorentz group that obeys the quadratic equation on R4 :
(t, x, y, z) |--> t2 -x2 -y2 -z2
The four connected components are non-simply connected and therefore this strongly infers that in a three-dimensional Euclidean space the electron would have a non-simply connected 3D topology as demonstrated in our proposed dressed electron model (see animation above).
Also in our proposed dressed electron model the coupled magnetic dipole charge and electric charge constituting the unified EM charge of the electron under this topology, the mass of the electron is the total EM flux focused in a dimensionless point, center of mass, located at the center of the proposed horn spheroid (https://mathworld.wolfram.com/HornTorus.html) topology of the electron (see figure). Therefore there is no conflict between dressed electron model and the accepted bare model thus a dimensionless point massive particle.
Actually it explains how both models bare and dressed can coexist without conflict. The radius is of the proposed unified bare-dressed electron model is the reduced Compton wavelength ƛ~3.86x10-13m larger radius as the classicall and therefore allowing a surface velocity equal with c or less and therefore classically explaining the known spin angular momentun value of the electron (√3/2)ħ as being generated by actually the electorn physically spinning as first suggested by

I don't claim that the real and imaginary part of the operator J+2 vanish; I claim that <J+2>=0 implies that the real and the imaginary part of the expression of <J+2>, which are both numbers vanish; x+iy=0 implies that x=y=0 IF both x,y are real, and in this case are, since Jx,Jy are Hermitian.
The expression <J+2>=< Jx2-Jy2> +i<JxJy+JyJx> results from the expression of J+2 by linearity; J+2 is linear.

I am familiar with elementary quantum mechanics which is a non-relativistic treatment of a single particle interacting with a given potential energy function produced by a fixed (given) environment. I don't understand quantum field theory and searched for a book with a title like "Quantum Field Theory for Dummies". The closest thing that I could find to that is 300 pages long. I have a question that maybe has a quick answer that can be given without reading 300 pages (I am trying to learn a lot of things so quick answers are appreciated if possible). My understanding from the first few chapters of that book is that what was a wave function in elementary quantum mechanics becomes an operator in quantum field theory. The operator is a function of time and space coordinates so there is a different operator for each space-time point. What I don't understand, even after reading a few chapters, is what that operator operates on. In elementary quantum mechanics, operators operate on elements (state vectors) of a vector space (a Hilbert space) and I know the mathematical significance of these elements (state vectors) that the operators operate on. I have no idea of what the entities are that the quantum field theory operators operate on. Can this be explained to a person with my level of education in a few paragraphs?

Dear Dr. L.D. Edmonds
You can try the Book by Prof. H. Hankel, many years ago I read it. Is not well-edited but it is a wonderful forgotten piece of the origin of the second quantization, that is, the quantization of the fields as really it was conceived for solidists. It is much easier to read than Prof. Bogoliubov and Shirkov's classical monography.

1) Do we need Spin Constant? why and why not?
2) Do we need Quantum Constant for motions? why and why not ?
3) Do we need Entangle Constant? why and why not?
4) What will be scenario for "theory of relativity" after discovery of these 3 constant values
5) how much modern physics will get change when we can "see" exact states...Past Quantum State Level-1 (PQ 1). Current Quantum State Level-1 (CQ 1) and Future Quantum State Level-1 (FQ 1)
6) Will such discoveries enhance Qubits to cross threshold level to simulate different universal systems. especially Biosphere webs with true paths in past and future?
7) How the generation of such a huge Data will be handled, will it over burdened?
8) Will it be end of Solid state and Quantum world for knowledge and only further applications will left to develop and understand with more perfection?
9) What will be after the Quantum ? any ide, any clue? any new dimensions? as we are going to cross 3rd dimension and getting enter into 4th dimension "physically"

The importance of the conservation laws in physics, if they not more than the physical constants, certainly, is not less than them. The conservation laws in physics define the boundary between possible events and the impossible.
If we ignore the law of conservation of energy, we can build a machine in our imagination that produces energy from nothing. That is, we will have an erratic universe that is more compatible with our imaginations than with observable realities.
Over the course of the last century, physics has been plagued by many problems, and their numbers are increasing day by day, to the point where modern physics is in a state of stagnation and crisis.
These problems are due to the fact that in modern physics, there is a law of mass-energy conservation, but there is no law of conservation of amount of speed. I first proposed the conservation law of the amount of speed in 1387 (1992 AD) and published it in the Persian language.
The conservation law of the amount of speed shows that the universe behaves more realistically and accurately than we ever imagined and that the whole universe is an automated and highly precise system.

Over the past 400 years of development, physics alternately replaced each other in the era of a rational-physical (model) and formal-mathematical method of describing the world.
Today, formal methods of describing phenomena have exhausted themselves. Therefore, it is necessary to move from the tradition of axiomatization to a visual model description, to logic, to common sense. We must swim against the stream to the sources, return to JK Maxwell, JJ Thomson, Lord Kelvin and Louis de Broglie. Above all, it is necessary to realize the role of the electromagnetic field as our environment. The study of its structure and its place in the picture of the world is relevant. Modern physics in general does not set as its goal the study of the nature of fields. The electromagnetic field is not in the parameters of the Standard Model.
Today we consider Maxwell’s electromagnetic field an invisible dispersed gaseous medium that fills all space. The smallest particles of the field - gravitons - continuously move at the speed of light. The rotational flows of gravitons is a magnetic field. The translational flow of the electromagnetic field we consider an electric field. Divergent vortex flows we know as transverse radio waves. The white noise of the field medium we record as microwave background radiation. Longitudinal waves in the medium arising from accelerations and shock perturbations of space objects, we now call gravitational waves. We are convinced of the existence of an electromagnetic field as a global environment whenever we bring a mobile phone to our ear.

I think that only people create difficulties for themselves in order to overcome them later. Nature is perfect in its simplicity. Today we do not have a sense of nature. Matter does not exist for us - we solve equations only.
Protons do not push each other out of the nuclei of atoms. The charge has no central symmetry. A charge is a thin ray of gravitons (quanta of an electromagnetic field) rotating at the speed of light. It is directed from the core outward, as shown in the diagram. Figure taken from the book "Electromagnetic Gravity. Part 2" in my profile.
Modern physics claims the innate property of the masses to attract each other (through the exchange of particles). This is medieval mysticism. To repel each other (due to thermal motion) is an innate property of the masses. The pressure of the external environment of the electromagnetic field holds the protons in the nucleus (it pushes them towards each other). Gravity is the action of repulsive forces, not attraction.
Relevant answer

Dear Valery!
You can also ask why do electrons repel each other and otherwise do they cause the chemical bonds.
The assumption is simply wrong that atomic nuclei consist of separate protons and neutrons. Atomic nuclei are spatial grids of particles (light mesons, mostly muons but also kaons) in a highly symmetrical arrangement. Protons and neutrons consist of the same particles as nuclei. Unstable nuclei emit protons and neutrons because this particles are more stable than the starting nucleus and not because protons and neutrons are preformed within the nuclei.
Insofar is present particle physics merely a theoretical gibberish about the microcosm.

This discussion considers, although not regularly offered at sophomore-level, that general relativity (GR) gives a better basis in undergraduate courses, and can be derived using [1].
This is useful because GR underlies much of the contemporary understanding of modern physics, including the big bang, pulsars, quasars, and gravitational waves.
As shown in [1], the laws of SR are just often simpler when they work in-between inertial frames, as originally stated.

Thanks for the apology, André Michaud , no problem with me.
It is interesting how all topics which somehow touch upon physics paradigms are divisive and lead to bitter fights, just as bitter as those between advocates of different religions. It does not speak well of us Scientists ... On these topics, I also agree with Daniel Baldomir , but I do not have a solution to most of these problems. Nobody has, probably, it seems to be in the human nature.
I have seen these bitter wars between ideas to flame up many times. It is not always a guy with an alternative theory/paradigm challenging the "establishment" scientists and being rebuked by them; invariably, guys with other alternative theories start fighting the first proponent just as viciously. Sometimes I think that our culture (basically the Western one) errs in attaching so much glory and rewards on scientific achievements.
I always try to impress one thing onto young would-be-scientists: NEVER, but really never, say that somebody else was wrong. Not unless you first discuss face-to-face with him/her, and absolutely never when they are dead. Remember that, in the long run, everybody will be proved wrong. Plus, it is in bad taste. Rather, focus on what you have in mind. Be Popperian, and try honestly to find the weak points in YOUR ideas, to disprove yourself. If others see that you are not attacking anybody, and that you honestly tried and your idea still stands, maybe they will be more willing to listen.
Returning to the original question: I think it is severely flawed, for the simple reason that NO theory can be EVER proved correct. Physics theories are just models of reality and none of them is definitive. There exist (occasionally) experiments that are in a clear conflict with a theory; in such a case that theory will eventually die (and yes, most likely only after all its proponents are buried). But an experiment that does not conflict with a theory is ineffective in proving anything. It is simply not in conflict, which is far from being a proof.

It also satisfies the Equi Partition Theorem and the Principle of Reuse/Recycle by Nature, which Modern Physics does not use. It uses Muon and Anti Muon as building blocks.
It proposes uses of a Space Field which can be called Dark Energy, Higgs Field, Ether, Prana or Chi.

Dear Sunil,
Modern Physics can give us a simple picture of the atoms. Look at the my picture from the book "Electromagnetic Gravity. Part 1" in my profile.
There is an example of “shielding” of weak interaction. Figure shows a block diagram of alpha-particle. The protons p1 and p2 and the neutrons n1 and n2 form a closed circuit. The moments and charge tubes of protons direct outwards, and the moments of neutrons direct inward. The total moment of the particle is zero. No nucleons have an orbital moment. They rotate only around its axis. The upper proton (as seen from the top of the figure) rotates counterclockwise. The lower proton rotates clockwise. Neutrons rotate around the axis in opposite directions too.
The diagram shows how in the nucleus of an atom the forces affect the neutrons that prevent them from falling apart. The free protons p1 and p2 and the protons bound in the neutrons n1 and n2 form a strong four-link power circuit. The components of neutrons — two electrons and two antineutrinos (two quarks) — are enclosed within this circuit. Protons chain quarks, the chain does not allow them to transfer their energy to the external environment, does not allow increasing their size.

Relevant answer
Answer
Dear Lena and Konstantinos,
It is not a spurious question as you might think. It is a question of the philosophy of science and not a pure scientific question as such. Democritus and Einstein are separated by many centuries. Natural science as we know it is only few hundred years old and it always expands; so a direct comparison from this perspective is meaningless.
What is meant here is the relative strength of the conceptual and perceptual merit of their ideas or theories and also prescribes the criteria for making this judgement in the following way: “ What the historical, social and scientific practices (as the criteria of knowledge) of the last few centuries tell us about who is right?”. Of course I have my own opinion on this subject and that influences my work and my view on natural science. This question is meant to challenge the generally perceived notion of “science” (particularly physics) both by the physicists and the general public.
There are two streams of philosophy of science (natural philosophy) and both of these originated with the early Greeks. One stream (dialectical materialism and classical materialism including Newtonian physics)) represented by Heraclitus, Leucippus, Democritus, Aristotle, Epicurus and others among the important names like Spinoza, Hegel, Marx; flows still today and to which I subscribe. The other stream (mathematical idealism) represented by Pythagoras, Permenides, Plato and other innumerable official philosophers and theologists of various epochs including the modern Vatican, form the essential basis of Einsteinian (New) Physics. On the basis of the above criteria of knowledge, I assert that field-based Einsteinian physics provides no positive knowledge of the world but only mathematics driven myths and phantasm. I know that it would be outrageous to many; but I am trying to justify my stance through my various works and publications (books, journal articles) and public media like RG. Please see my comments in various RG forums, specially the following few:
An atom in the conception of the Leucippus and Democritus is the smallest unit of elemental matter (that still retains the property of the bulk matter); forms the essential basis for modern science (especially physics, chemistry and biology). With the present knowledge of the structure of atoms, the whole wealth of knowledge is summarized in the Periodic Table; which was in fact formulated even without the knowledge of atomic structure. The knowledge about the structure of atoms was built up through centuries and was impossible for Leucippus and Democritus to know; but it was their essential concept of the atom that led natural science to the present stage and naturally also ushered in the revolutionary quantum phenomena. Social/historical practice, technology, industry etc., that followed from that concept prove its validity in everyday modern social life.
Einsteinian physics is here with us for more than hundred years; but provided not a single social/historical practice, technology etc. The virtual edifice of “field”-based new physics, which Einstein himself called the “Castle in the Air” is only metaphysics that has dragged back physics to the level of decadent medieval scholasticism. We have apologist official physicists like Carroll (in the YouTube video) to justify Einsteinian (abstract) "field"- physics (as opposed to Democritus' material atoms) through abstract mathematical cobweb-spinning and contrived and fraudulent experimental “proofs”. The physics based on Democritus’ concept never needed centuries long (or any ) “proofs” at all! Even now his physics is “proved” through our everyday life experience!

  • asked a question related to Modern Physics
Question
16 answers
Yes, in three topics at least, as shown below, usually called modern physics: special relativity (SR), general relativity (GR), and quantum mechanics (QM).
The basis of both SR and GR, for more than 100 years, is the model of spacetime, a 4D universe, as first explained by Minkowsky [1]. To contrast, Newtonian mechanics was based on a 3D universe, where time is absolute and NOT influenceable by an experimenter.
From a basic theorem in topology, and even more basic type theory results, a continuous path in 4D may create a discontinuous path in a lower dimension, such as in 3D; any one-to-one mapping between spaces of different dimensionality must be discontinuous in that a continuous path in one space maps into a broken path in the other.
Therefore, there are discontinuities in the transition to 3D (Newtonian mechanics) from SR or GR, even at v << c, from an arbitrary path in 4D. Some paths in 4D may be continuous in mapping to 3D.
The same topological argument applies to the relationship between Newtonian physics and QM. The quantum results WILL NOT always correspond to the Newtonian results in the limit of large quantum number n or, equivalently, in the limit of Planck’s constant h going to zero. The topological spaces have different dimensions, and discontinuities will result. Again, some paths in higher dimension may be continuous in mapping to 3D.
This is not a conceptual choice only, but must be also experimental. Reality, experimentally, must be at least 4D, it “does not fit” inside 3D in all cases.
The answer chosen here also contributes to explain current differences of opinion in these areas (SR, GR, QM), and the “weirdness” of QM logic, whereas the discrepancy is due to a difference in dimensions, and its experimental effects, that are not considered. Such differences may be just illusory, seem from a meager 3D view, impotent to reach 4D.
Thus, modern physics, including SR, GR, QM, and other fields such as Cosmology, is expected to show conceptual and experimental differences with Newtonian physics, even when v << c, n >> 1, or h goes to zero.
The intuition gained in Newtonian physics is not efficient in modern physics, and will lead to contradictions in an arbitrary path taken in nature.
[1] Minkowsky, 120 years ago, that "Henceforth, space for itself, and time for itself shall completely reduce to a mere shadow, and only some sort of union of the two shall preserve independence."
Relevant answer
Answer
The mapping from 4D to 3D is not one to one, it is a projection, therefore the reasoning doesn't apply.
The limit of quantum mechanics when h tends to zero is classical mechanics, but not any classical mechanics. Contrary to what is widely believed, the limit is geometrical optics, not corpuscle mechanics. Thus neither is subsumed by the other, they are different theories. They can't be the same since they are different representations of a same Poisson structure.

Question

The crucial problem of Einstein’s theory of relativity is that the relative spacetime (length contraction and time dilation) is not true.
If the relative spacetime was true, in any sense, Einstein’s theory of relativity should be a very great theory. But, in fact, relative spacetime does be false.
The crucial experiment is that, in the high energy accelerator, the speed of particles is the highest close to the speed of light and the condition is the most stable, precession and repeatable. But, no length contraction and time dilation was observed in it. Then, why the relative space and time was observed in other objects? It is certain, these observations are false. For example, it is not true that the life of the highspeed mesons is longer than that of the stationary ones. First, there are not the so-called stationary particles. Second, the mesons decay with N(t)=N0e-kt. The lifetime of some mesons is longer than others. Third, the mean lifetime is determined with N0. If the number N0 of the so-called stationary mesons are larger than that of the highspeed ones, the mean life of the so-called stationary mesons may be longer than that of the highspeed ones.
We analysized a paper for the lifetime of highspeed muons. It is shown that the conclusion is questioned:
Assuming two groups of mesons Na0=10 decaying with Na(t)=Na0e-t/Ta and Nb0=100 with Nb(t)=Na0e-t/Tb . After a time duration t, as e-t/Ta=0.01 and e-t/Tb=0.001. One muon is observed in a distance of L.
Then, there are the conclusions:
first, we cannot know, whether this one muon is belong to Na0 or Nb0.
Second, we cannot know Ta or Tb from this one muon.
So, the question is: what was measured in “Measurement of the Relativistic Time Dilation Using μ-Mesons”.[1]
In [1], it was measured: The numbers of N0=563 and N(t)=408 per hour. i.e., on average, 1.56*10-7 muon is measured in one μsecond.
So, in [1], it is not 563 muons of one group were measured. In a very big probability, it implies that 563 groups of N(t) were measured and one muon of one group was measured.
From the above conclusions we know, first, they cannot know the mean lifetime T from one muon of one group.
Second, the mean lifetime for every group is different. But, they give a same mean lifetime for all of the 563 groups.
So, the conclusion in [1] is questioned.
In “Measurement of the Muon Lifetime”[2], it is reported that “We find a muon lifetime of (864.6 ± 1.2) ns”. We know, in the papers to prove time dilation, the mean lifetime of the so called stationary muons is 2.19μs. If [2] is validly related with these papers, it means that all the papers for proving time dilation are invalid.
As the relative spacetime does be non-existent, the hypotheses and “theories” based on it are false. Unfortunately, in the past 110 years, many theories and experiments were based on it. A lot of false stories were produced. More unfortunately, these false stories are regarded as great theories and the experiments are very dominated.
So, if we hope to understand modern physics and Einstein with his theory of relativity, we have to first know whether or not the relative spacetime is true.
And, may I advise the friends who try to advance the theory of relativity or to develop new theory from it. As the space and time are not relative, these tries are unfruitful.

Why dark energy produces a repulsive force field is a bit complicated. Quantum theory says virtual particles can pop into existence for the briefest of moments before returning to nothingness. That means the vacuum of space is not a true void. Rather, space is filled with low-grade energy created when virtual particles and their antimatter partners momentarily pop into and out of existence, leaving behind a very small field called vacuum energy.
That energy should produce a kind of negative pressure, or repulsion, thereby explaining why the universe's expansion is accelerating.
In recent years, several papers have been published to solve dark matter and dark energy problems. The emphasis of these papers is on quantum vacuum and faster than light speed. A new theory proposes that faster-than-light particles known as tachyons could answer a lot of questions about the universe. According to a paper published in European Physical Journal C by Herb Fried from Brown University and Yves Gabellini from INLN-Université de Nice, may be a kind of particle called a tachyon.
A tachyon is a hypothetical particle that always moves faster than light.
Motion is an intrinsic property of physical existence. But there is a problem about concept of acceleration in theoretical physics. At the beginning of the 20th century, Newton’s second law was corrected considering the limit of speed c and the relativistic mass. At that time there has not been a clear understanding of the subatomic particles and basically there was little research in high energy physics . It means we need review our understanding about acceleration.
In addition; recent researches show, to solve the problem of dark energy, dark matter and inflation theory, quantum vacuum and faster than light speed should be considered and analyzed, which was done in following book. But regardless to reconsidering the relativistic Newton's second law, how can we resolve the faster than light speed problem? Besides that, the old definition of acceleration prevents the recognition of the nature of acceleration. Due to this reason in 1987, CPH Theory has begun by review the structure of photon, sub-quantum energy and faster than light speed.
Moreover, one could explain the expansion of the universe better and more real through reviewing relativistic Newton’s second law.
For faster than light speed see section 1; review acceleration and the relativistic Newton's second law, see section 5 of following book:

The definitions of temperature and entropy are related to the concept of "thermodynamic equilibrium". In the absence of equilibrium, these concepts cannot be introduced. A black hole in combination with radiation presents a closed system, one of the subsystems of which (radiation) is close by its parameters to equilibrium, but other subsystems (black hole itself) do not. I.e., if the emitted radiation carries away entropy, this does not mean that in the remaining part it (being additive) is reduced by the same amount, because the very notion of a black hole cannot be introduced.

Black body radiation of the black hole tell us only about ratiation itself but not about black hole. For statement that "black hole is in equilibrium" we need model of black hole with it's internal structure. If this model indicates that black hole is in equilibrium, we musy agree with this. Without such a model we cannot speak about equilibrium of a black hole.

It is said of general relativity that it has been experimentally proven.
But what about experiments involving black holes and the recent LIGO experiments - do they really uphold GTR?
Relevant answer
Answer
   To doubt about one theory, any theory, is always a healthy exercise and the GRT was one of the theories that was tried to modify several times. What is not so healthy is if the discussion transforms in a war between personal opinions without given enough information on where can be the fails and if there is one real alternative. I think that it would be very worthy if it would be possible to present these "weak" and "strong" points.
1. For more than one hundred years very good scientists were following the GRT and trying even to find a better theory. One of them was Einstein with the unified theories trying to unify electromagnetism with the gravitation (classical theories), for example Kaluza-Klein theory. This has failed.
2. More recently String theory or its generalization in M-theory found a mode of oscillation with coincides with the graviton. This is very appealling because unifies quantum mechanics and gravitation (with the possibility of introducing the gravitation in the context of the Standard Model) but it only works at very low energies.
3. With the simple Hilbert action and Einstein's motion equations this old theory of GRT follows to be the simplest and more accurate theory of gravitation for explaining the present phenomenology.
   There are several basic problems associated to gravitation
4. It is a very weak interaction (difficult to carry it to the lab) if we compare it with the other three interactions and the geometrical Riemann interpretation introduced by Einstein is not possible to be introduced within perturbation metheds (renormalization group).
   Perhaps what would be interesting is to know what are the concrete points of criticisms that can be put to GRT instead of transforming this fantastic achievement of physics as a personal attack to his creator.

Dear Johan,
Your are so right!
Alfred Korzybski wrote in 1921:
"Bending facts to theories is a constant danger, whereas bending theories to facts is essential to science. Epistemologically, the fundamental theories must develop in converging lines of investigation, and if they do not converge, it is an indication that there are flaws in the theories, and they are revised."
I think this is the issue here. Too much bending facts to self consistent theories in the physics community and not enough revisions undertaken to match theories to facts.

<< In theoretical physics, particularly in discussions of gravitation theories, Mach's principle (or Mach's conjecture[1]) is the name given by Einstein to an imprecise hypothesis often credited to the physicist and philosopher Ernst Mach. The idea is that local inertial frames are determined by the large scale distribution of matter, as exemplified by this anecdote:
You are standing in a field looking at the stars. Your arms are resting freely at your side, and you see that the distant stars are not moving. Now start spinning. The stars are whirling around you and your arms are pulled away from your body. Why should your arms be pulled away when the stars are whirling? Why should they be dangling freely when the stars don't move?
Mach's principle says that this is not a coincidence—that there is a physical law that relates the motion of the distant stars to the local inertial frame. If you see all the stars whirling around you, Mach suggests that there is some physical law which would make it so you would feel a centrifugal force. There are a number of rival formulations of the principle. It is often stated in vague ways, like "mass out there influences inertia here". >>
Somewhere else, it is written about Geometry of Newtonian gravity :
<< According to general relativity, objects in a gravitational field behave similarly to objects within an accelerating enclosure. For example, an observer will see a ball fall the same way in a rocket as it does on Earth, provided that the acceleration of the rocket is equal to 9.8 m/s2 (the acceleration due to gravity at the surface of the Earth). >>
My conclusion is that, for an arbitrarily chosen experimenter (whatever his state of motion), a material body whose motion is rectilinear and uniform generates no gravitational field and it can create a gravitational field only when its movement is accelerated relative to to the experimenter.
Thus, in the same way that the existence of a magnetic field is only caused by the motion (possibly uniform) of electrically charged bodies in the reference frame of the experimenter, I conclude that the existence of a gravitational field is only caused by the accelerations of material bodies in the reference frame of the experimenter.
Thus, if a planet is constantly at rest with respect to an experimenter, he/she/it will conclude that the gravitational field produced by this planet comes from the superposition of the gravitational fields produced by the atoms that make up this planet because each atom contains electrons whose motions ate accelerated around the atomic nucleus. Moreover, accelerations of the gases expelled by the engine that propels the elevator can be the source of the gravitational field in Einstein's thought experiment. Written in French:

Dear Rommel,
Newton then Mach and to a certain extent also Einstein formulated the "nihilist" hypothesys in the conception of what is *in between*  objects with mass (from Quarks to Quasars). Provided that it is not even well defined what objects are, Quantum electrodynamics which is the best tested theory so far, teaches us that  emptiness does not exist, in this view the Mach hypothesys is totally void of any meaning. Mach suggested that universe is determined by masses and their relations, QED and QCD teach us that governing dynamics are strictly related to an active Background, it is all the way around.
Newton looked for an absolute reference frame which he resonably found in the fixed stars, Mach did give  power to the stars to influence behavior of other "objects" We know that they are sufficiently far to nullify any gravitational or inertial influence.

I have a question regarding one unusual (thought) system.
Some years ago at one Russian forum we discussed one thought device that, as its author claimed, can provide one-directional motion and only due to the internal forces. The puzzle had been resolved by Kirk McDonald from Princeton Univ. I attach Kirk's solution. I wish to say that the author of the paradox is Georgy Ivanov but not me.
Anyway, Kirk found that there is no resulting directional force. But one puzzle of this device remains. The center-of-mass of the device should move (in the closed orbit) only due to the internal forces. I marked this result of McDonald in the file.
In this connection, two questions arise:
1. Why the center-of-mass moves despite the total momentum conserves?
2. If the center-of-mass can move and this motion is created by the internal forces, is it possible to change the design of the device to provide one-directional motion?
Formally there is no obstacles to realize it. The total momentum conserves... Could some one give the answers to them?
This thought device works not on the action-reaction principle and if similar device can be made as hardware, it could be a good prototype for the interstellar flight thruster.

Answer
Your interpretation is utterly incoherent and unsupported by anything in the text. Einstein merely says a point moving in k must have a value of x' which is constant. In other words, the value of x' for a point moving with k must be constant. Mere obvious kinematics, following from the definition of velocity. Nothing is ever said about x' being ``attached'' to k. Nor is it true that it is measured using moving rods. Rather, x is measured using rods at rest with K, so is vt, and therefore the difference between the two is also a distance measured by rods at rest with respect to K. Your screaming ``Nonsense'' merely shows lack of understanding. The idea that such a distance ``cannot be measured'' is again a figment of your imagination: there is no difficulty whatever in measuring the distance between two moving points.
This discussion has, of course, no meaning: your only point is to denigrate relativity, for purposes best known to you. I have stated the truth of the matter, by following the actual original text (which you were afraid to quote) as closely as possible. For any interested readers who might have been confused by your nonsense, this should be enough. You I do not think worth an additional second of my time.

   Stam,
   You do not enter in the question and you go to other things. I am speaking on your sentence which is absolutely wrong. You mixture things in a nonsense and it seems that you can pick up vacuum, representation of groups, spin, spinors, coordinates, ...etc.
   Let me then to change (no to the inflation of Guth) and to go to the initial remark that I have made you.   
   Although the Lorentz group SO(3,1) is locally isomorphic to the special linear SL(2,C), and you can interpret the spinors as a kind of Lorentz transformations. This is not the case and you need in fact to take relativistic representation of the spinors, you have to go to the subgroup SU(2)xSU(2) e.g. Dirac, Weyl or Majorana. But this doesn't means that you have a coordinate dependence as every physicist knows. 
   On the other hand, vacuum polarization that lies at the core of Haag's theorem. Any interacting quantum field (including non-interacting fields of different masses) is polarizing the vacuum, and as a consequence its vacuum state lies inside a renormalized Hilbert space Hq that differs from the Hilbert space Hf of the free field. Although an isomorphism could always be found that maps one Hilbert space into the other, Haag's theorem implies that no such mapping would deliver unitarily equivalent representations of the corresponding canonical commutation relations, i.e. unambiguous physical results that surely Agostino could speak a lot about of them.
   The problem is that there are "hooligans" of saying words without meaning but within the Standard Model and it seems that they are always right. Most practitioners (by the way I doubt that you are) of QFT appear to ignore the implications of things Haag's theorem entirely and prefer to go ahead producing numbers, or what is worse words, without understanding basic physics.
    I would be very surprise if you could respond me directly to the questions and no mentioning personal features as basic Lie groups, irrelevance, ignorance, etc...

In a recent paper published by Journal of Modern Physics, 2015, Walter Petry argues that it is possible to come up with non-expanding, non-singular universe. He explains that there is no expanding space, and Hubble law does not indicate that.
What do you think? Your comments are welcome. 
Relevant answer
Answer
Victor,
One of the contributing factors that promote the idea of an expanding universe is the decrease in energy of light photons that arrive here from the far reaches of the universe.
Per Maxwell’s work, light and radiation have magnetic and electric properties. The work of Planck and Einstein indicated radiation is made up of quanta (photons) and is not continuous. It should be remembered that Maxwell’s differential wave equations only indicate that radiation translates in a waveform but is not a wave itself. Therefore, by connecting the two bodies of work, the quanta (photons) derived by Planck and Einstein are the constituents that trace Maxwell’s waveform when they translate.
Since the photon has electric properties, it has the capability to interact with another photon through the electric force. For example, a light photon can interact with a CMB photon if their paths cross. During such interaction, an infinitesimal quantity of energy is transferred from the more energetic light photon to the lesser energetic CMB photon. Therefore, light photons that travel extremely long distances through space will undergo very many interactions with CMB photons and thus, will lose measurable quantities of energy. Hence, an expanding universe need not be necessarily invoked to understand how light photons that travel long distances lose energy.
Any non-spherical model of the photon has to show how it traces a waveform when it translates and how it gives its magnetic and electric properties. A photon model that realizes the above properties has been derived incidentally to the derivation of the electron. A view of the electron is given in Figure 2 of the attached article and view of the photon is given in Figure 1.
In Figure 1, the photon fiber is referred to as a heat fiber (please see footnote 1 in the article as to why). The energy of a photon fiber, given by Planck’s law E = hν, arises from its light-speed oscillatory motion along its length and about its origin (which is at its mid-length), rather than its translational motion. Its oscillatory motion is perpendicular to its translation; thus, a waveform is traced as it translates. The level of energy given by the fiber oscillation is related to its oscillation range or stroke; shorter strokes yield shorter wavelengths and higher frequencies, and thus greater energies.
Per Figure 1, perpendicular elements develop along the fiber length, due to Lorentz length contraction, as it oscillates back and forth at light-like speed along its length. These perpendicular elements give the photon’s B-field as it twirls about its origin. The electrical force potential (E) of the photon fiber is derived from and is synchronized with “B”; changes in “B” give “E” per Maxwell’s equations and is perpendicular to “B”. It should be noted that “B” is a field and “E” is a force potential that results from movement of the field.
To see how two photons interact and how a transfer of energy between them occurs, please refer to Section 11.D.2 in the book from which, the attached article is excerpted.

The physical vacuum is not ‘nothing’: ‘nothing’ means  ‘not being’, neither matter nor energy, neither space nor time, nor any physical property; the physical vacuum, instead, is "something" physically existing in space-time, in quantum mechanics represented by a state vector in accordance with non-zero and characteristic properties.
The difficulty for the old mentality, which lasts through Parmenides’ thought, to conceive the vacuum seems to be related to the theory of archaic Greek thought mentioned by the philosopher Ernst Cassirer about a “mythical age”, understood as the transition from primitive thought to the rational adult, where there is no distinction between word and thing.
Referring to Cassirer, philosopher Guido Calogero, saw in this attitude of the first Greek thought an " archaic coalescence ", a kind of fusion of language, reality and truth. for which the Greeks had a vision of reality as a "show"; therefore, not distinguishing between visibility, existence and thought: what was only visible really existed and thus could be thought and hence the difficulty of thinking ‘not being’ and, vacuum, that are not visible and then do not exist.
Moreover, according to Aristotle, the cause of the movement of bodies was not in the body itself, but in the medium. A bullet, once thrown, would continue to be in motion because pushed from the air, which continually scrambles to fill the void left by the bullet as it passes.
A body would therefore always be subject to a force during the motion and its speed would be directly proportional to it and inversely proportional to the resistance of the medium. It follows that the resistance in the vacuum would be nothing and the speed of the body would become infinite, that is, the body would have the characteristic of ubiquity.
Averroes (XII century) opposed this theory, arguing that is experience of everybody all that motion always takes place through a medium, and that resort to a hypothetical incorporeal force would seek the cause of things not in reality but in an imaginary abstract world.
Descartes published his Principia Philosophiae, where he claimed - among others - the non-existence of the vacuum referring to its identification of extension and corporeal substance (res extensa). In the same year the physicist Evangelista Torricelli described in a letter the experience of his famous barometer in which he managed to prove that the vacuum can exist in nature and that air has weight, thus putting an end to the millenary philosophical discussions on 'horror vacui’.
Aristotle refutes the positions of atomists in the discussion held in the Physics (IV, 6-9), arguing in Chapters 7 and 8 that the movement does not imply a vacuum; on the contrary, if it actually existed, it would prevent the movement, as confirmed by the analysis of displacement of a body. Nor are valid the arguments based on the existence of rare and dense, nor the motion of ‘graves’ downward. The Greek philosopher also considered that the sub-lunar world consisted of four elements (fire, air, earth and water) and argued that to each of them corresponded a natural place, from which they could only be moved by violence. In their natural environment elements had no weight. The air, then, for the Greek philosopher and his countless followers did not weigh, nor exerted pressure.
Continuing the quote of Aristotle's thought, everything is still in the vacuum, therefore the vacuum must be denied.
Scholastic philosophy accepted most of the Aristotelian arguments, summarizing its position in the well-known adage ‘Natura abhorret a vacuo’. In the modern age the adhesion of Gassendi to the atomistic doctrines led the philosopher to accept the idea of vacuum, rejected, instead, by Descartes because of his identification of extension and corporeal substance.
Now, we should deal with the subtle but sharp distinction between "absence" and "nothing": in fact absence is not identical to nothing. This risk may be lurking for all, this vacuum that is not an absence, but nothing.
The Heisenberg's Uncertainty Principle  leads to believe (for purely philosophical intent) that the quantic vacuum is equivalent to nothing. The  astrophysicist says: " A good disclosure should never misrepresent or obscure the consolidated results of scientific research, especially when, as in this case, the average reader is not able to critically evaluate the correctness of the statements." For example, also the Italian astrophysicist Marco Bersanelli, spoke when he explained that "the primordial quantum vacuum” can give rise to a particle, and in principle to more complex physical realities. This means that the "vacuum" of the physicists is radically different from the “nothing” of the philosopher.
What the extrapolations of the physical vacuum to the metaphysical ‘nothing’ have to do with the Galilean science?
In the Universe, say the most reliable theories, there should be an equal amount (a symmetry) between matter and antimatter, two states that, if they come into contact, will annihilate, that is, become nothing. And since in nothing, in a vacuum, it is impossible to distinguish one part from another one, there is also the highest symmetry. But physicists have now discovered that the symmetries are not stable: they are made to be broken.
In modern physics, after having established, at least conceptually, the existence of an absolute  vacuum, it is returned to the initial idea that even the vacuum is something other than nothing, because it has physical properties readily apparent. The empty space, understood as a container with no properties, is therefore not possible.

In string theory a point particle is replaced by a one dimensional string. Ahluwalia [1] has argued that the notion of a point-particle is no longer viable in a stabilized form of the combination of the Poincare and Heisenberg algebras because the resulting algebra features a modified Heisenberg sector.

That certain operators have a discrete spectrum doesn't, by itself, imply anything about whether the dynamical degrees of freedom are point-like or not. For example, in quantum mechanics, the phase space volume is always quantized, but the spectrum of the Hamiltonian of a point particle can be continuous or discrete, depending on the potential and the boundary conditions. So what matters is what precisely is the area or volume these operators measure.

Actually it's a straightforward calculation: Let's assume that the original photon has momentum p in direction z (that is, px=py=0 and pz=p). Then it has energy E=pc.
Now imagine you want to produce a particle-antiparticle pair of non-zero mass m (assume without loss of generality that the momentum is so that py1=py2=0). Then, according to momentum conservation, their momenta have to be pz1+pz2=p, px1+px2=0.
According to Relativity, each particle has Ei^2 = (mc^2)^2 +c^2 pxi^2 + c^2 pzi^2 (where i=1 or 2). We have Ei^2 = (mc^2)^2 + c^2 pxi^2 + c^2 pzi^2 > c^2 pzi^2, that is, Ei > pzi c. Therefore we get (E1+E2)^2 = E1^2 + 2 E1 E2 + E2^2 > (pz1^2 + 2 pz1 pz2 + pz2^2) c^2 = (pz1+pz2)^2 c^2 = pz^2 c^2 = E^2, and therefore E1+E2 > E. That is, the energy of the two generated particles is larger than the energy of the original photon, which would violate energy conservation.

I'm layperson in physics, but I often read the sentence: matter is energy condensed. And I doubt if this claim is true.
Relevant answer
Answer
Marcos, you know that's an interesting question. I have often thought that in the past. But, the question itself is 'rather loose'. Still, I'm pretty sure I get your meaning.
OK, let's look at it this way. As you probably already know, Albert Einstein's famous equation E = MC^2, where E is the equivalent energy, M is the mass of the object (read that 'matter') of interest, and C^2 is the proportionality constant, equal to the speed of light in a vacuum squared. It's this correspondence that causes people to say things like "Is matter condensed energy?"
So, how do physicists know this is true? Consider nuclear fusion. Let's fuse a proton and a neutron together to make a Deuterium nucleus by slamming them together at some great speed. We must also keep track of the kinetic energy of the incoming particles and the out going nucleus. If you sum the mass of the proton and the neutron separately and then compare that number to the measured mass of a Deuterium nucleus, you will find that the mass of the nucleus is less than the sum of the parts. That difference in mass goes into the kinetic energy gained by the out going nucleus.
Wow, that's pretty obscure huh?
Let's look at another reaction. Let's combine a proton and an anti-proton. In this reaction, the proton and anti-proton TOTALLY ANIHILLATE. That is, they convert 100% of their mass into energy. They don't just break apart or anything like that, they totally convert into a gamma ray photon with energy equal to that predicted by Einstein. This is a well known and often measured reaction in the laboratory (e.g.: CERN's Large Hadron Collider).
Well, both these reactions are actually showing how matter can 'evaporate' into energy. (Speaking VERY loosely!). But the original statement is about 'condensation'. Does that really happen? Can we take just energy and produce matter? The answer to that question is 'yes'.
Aside from considering what happened at the beginning of the 'big bang', where pure energy created all the mass of the entire universe, is there a more practical example? Yes, this is also done frequently in particle accelerators. Heavier particles that have very short lifetimes (and therefore are not readily available for study in the laboratory) are synthesized/created on demand by slamming two particles together at very high speed (that is, having large energy). With some degree of predictability, a much heavier particle is created. Need a heavier particle? Go faster (more energy).
In a now famous example, this is how the Higgs particle was synthesized and detected at CERN. The Higgs particle is hundreds of times more massive than any conventional sub-atomic particle. So, in order to create one, the two particles that are collided must have fantastically high energies. And, that's why CERN's Large Hadron Collider cost so much money, took so long to build, and literally spans two countries.
I hope this helps.
