This report provides a brief outline and literature listing dealing with the discovery of the existence of Dynamical Space, and the subsequent generalisation to Maxwell Electromagnetic Theory, Schrödinger and Dirac Quantum Theory, and the emergence of Gravity as a quantum effect. This amounts to the unified theory of gravity and quantum phenomena....
Conference Paper
Recently the existence of space as a complex dynamical system was discovered, based upon various experiments going back to 1887. The early experiments by Michelson and Morley 1887, and Miller 1925/26, used light speed anisotropy detected with interferometers. Only in 2002 was the calibration theory first derived. More recently there have been other...

Full-text available
Experiments have repeatedly revealed the existence of a dynamical structured fractal 3-space, with a speed relative to the Earth of some 500 km sec−1 from a southerly direction. Experiments have ranged from optical light speed anisotropy interferometers to zener diode quantum detectors. This dynamical space has been missing from theories from the...
Article
Full-text available
This is a review of the numerous successful gravitational wave detections and the implications for the nature of space and time. The prevailing space time paradigm in physics was founded on the putative “null” results of the Michelson-Morley (MM) 1887 interferometer experiment to detect light speed anisotropy and which resulted in two different new...

Full-text available
Amaldi et al. in 1981 reported two key discoveries from the Frascati and Rome gravitational wave cryogenic bar detectors: (a) Rome events delayed by within a few seconds to tens of seconds from the Frascati events, and (b) the Frascati Fourier-analysed data frequency peaks being the same as the earth oscillation frequencies from seismology. The tim...

Shnoll has investigated the non-Poisson scatter of rate measurements in various phenomena such as biological and chemical reactions, radioactive decay, photodiode current leakage and germanium semiconductor noise, and attributed the scatter to cosmophysical factors. While Shnoll didn't pinpoint the nature of the cosmophysical factors the Process Ph...

Black holes are usually studied without including effects of the expanding universe. However in some recent studies black holes have been embedded in an expanding universe, in order to determine the interplay, if any, of these two dynamical processes. Dynamical 3-space theory contains time independent solutions for black holes, which are spatial in...
Article
Full-text available
The existence of space as a dynamical system was recently revealed in 2002, following the discovery that the Michelson-Morley light speed anisotropy experiment of 1887 was not null. Numerous later experiments have confirmed that discovery, as reviewed here, with the latest being the discovery of a very simple and cheap nanotechnology quantum detect...
Article
Full-text available
Gravity theory missed a key dynamical process that became apparent only when expressed in terms of a velocity field, instead of the Newtonian gravitational acceleration field. This dynamical process involves an additional self-interaction of the dynamical 3-space, and experimental data reveals that its strength is set by the fine structure constant...

The major extant relativity theories - Galileo's Relativity (GaR), Lorentz's Relativity (LR) and Einstein's Special Relativity (SR), with the latter much celebrated, while the LR is essentially ignored. Indeed it is often incorrectly claimed that SR and LR are experimentally indistinguishable. Here we show that (i) SR and LR are experimentally dist...

The 1991 DeWitte double one-way 1st order in v/c experiment successfully measured the anisotropy of the speed of light using clocks at each end of the RF coaxial cables. However Spavieri et al., Physics Letters A (2012), doi: 10.1016/j.physleta_2012.0010, have reported that (i) clock effects caused by clock transport should be included, and (ii) th...
Article
Full-text available
Experiments have revealed that the Fresnel drag effect is not present in RF coaxial cables, contrary to a previous report. This enables a very sensitive, robust and compact detector, that is 1st order in v/c and using one clock, to detect the dynamical space passing the earth, revealing the sidereal rotation of the earth, together with significant...
Article
We consider the quantum field theory of a model of an extended Nambu-Jona-Lasinio type with a QCD based nonlocal fermion current-current interaction which has global SU(Nc) symmetry. We obtain an exact bosonization of this model in four Euclidean dimensions using auxiliary bilocal fields and discuss the dynamical breakdown of chiral symmetry in the...
Article
A new technique for analyzing mesons and diquarks as and qq states bound by gluon exchange reveals how quarks acquire constituent masses. Our method, which involves the approximate reformulation of the Bethe-Salpeter equations for chiral QCD in terms of mass functionals, is covariant, has dynamically hidden chiral symmetry and is free of all diverg...
Article
The mass splitting between the I = 0 ω meson and the I = 1 ρ mesons due to the ππ intermediate state self-energy process accessible to the ρ meson is calculated in a QCD based model of the strong interaction. The calculation is completely self-regularizing with every physical meson quantity used calculable and completely determined by the parameter...
Article
We show how a meson effective action, in which all of the meson parameters are finite, arises from a “global color symmetry” model involving a nonlocal current-current (four-quark) interaction. As an application of this general approach we present a covariant analysis of the ρ-π system and thus obtain estimates for the ρ meson mass and the coupling...

Full-text available
We compare two generalisations from Newtonian gravity: (i) the Einstein-Hilbert route via curved spacetime, and (ii) dynamical 3-space, which introduced a velocity fiel formulation in place of the Newtonian acceleration fiel formulation. The dynamical 3-space is shown to give a parameter free account of the Hubble expansion supernova data, without...

In "Isotropy of Speed of Light" by Castano and Hawkins, arXiv:1103.1620, it is claimed, using a flawed theoretical argument, that the speed of light must necessarily be isotropic, independent even of experiment. The key false assumption made is that the round trip time must always be invariant wrt change of direction of the light path. This is show...

Observations of weak gravitational lensing combined with statistical tomographic techniques have revealed that galaxies have formed along filaments, essentially one-dimensional lines or strings, which form sheets and voids. These have, in the main, been interpreted as "dark matter" effects. To the contrary here we report the discovery that the dyna...

The laws of gravitation devised by Newton, and by Hilbert and Einstein, have failed many experimental and observational tests, namely the bore hole g anomaly, flat rotation curves for spiral galaxies, supermassive black hole mass spectrum, uniformly expanding universe, cosmic filaments, laboratory G measurements, galactic EM bending, precocious gal...
Article
Full-text available
Numerous experiments and observations have confirmed the existence of a dynamical 3-space, detectable directly by light-speed anisotropy experiments, and indirectly by means of novel gravitational effects, such as bore hole g anomalies, predictable black hole masses, flat spiral-galaxy rotation curves, and the expansion of the universe, all without...

Full-text available
An experiment that confirms the Fresnel drag formalism in RF coaxial cables is reported. The Fresnel `drag' in bulk dielectrics and in optical fibers has previously been well established. An explanation for this formalism is given, and it is shown that there is no actual drag phenomenon, rather that the Fresnel drag effect is merely the consequence...

The Apache Point Lunar Laser-ranging Operation (APOLLO), in NM, can detect photon bounces from retroreflectors on the moon surface to 0.1ns timing resolution. This facility enables not only the detection of light speed anisotropy, which defines a local preferred frame of reference - only in that frame is the speed of light isotropic, but also fluct...

The standard LambdaCDM model of cosmology is usually understood to arise from demanding that the Friedmann-Lemaitre-Robertson-Walker (FLRW) metric satisfy the General Relativity dynamics for spacetime metrics. The FLRW data-based dominant parameter values, Omega_Lambda=0.73 and Omega_m=0.27 for the dark energy and dark matter+matter, respectively,...

We report the discovery of an exact mapping from Galilean time and space coordinates to Minkowski spacetime coordinates, showing that Lorentz covariance and the space-time construct are consistent with the existence of a dynamical 3-space, and absolute motion. We illustrate this mapping first with the standard theory of sound, as vibrations of a me...

Full-text available
Doppler shift observations of spacecraft, such as Galileo, NEAR, Cassini, Rosetta and MESSENGER in earth flybys, have all revealed unexplained speed `anomalies' - that the doppler-shift determined speeds are inconsistent with expected speeds. Here it is shown that these speed anomalies are not real and are actually the result of using an incorrect...

Results from two optical-fiber gravitational-wave interferometric detectors are reported. The detector design is very small, cheap and simple to build and operate. Using two detectors has permitted various tests of the design principles as well as demonstrating the first simultaneous detection of correlated gravitational waves from detectors spatia...

Full-text available
We show that modelling the universe as a pre-geometric system with emergent quantum modes, and then constructing the classical limit, we obtain a new account of space and gravity that goes beyond Newtonian gravity even in the non-relativistic limit. This account does not require dark matter to explain the spiral galaxy rotation curves, and explains...

We apply the new dynamics of 3-space to cosmology by deriving a Hubble expansion solution. This dynamics involves two constants G and α- the fine structure constant. This solution gives an excellent parameter free fit to the recent supernova data without the need for ‘dark energy ’ or ‘dark matter’. The data and theory together imply an older age f...

Full-text available
For some 100 years physics has modelled space and time via the spacetime concept, with space being merely an observer dependent perspective effect of that spacetime - space itself had no observer independent existence - it had no ontological status, and it certainly had no dynamical description. In recent years this has all changed. In 2002 it was...

NASA has claimed the discovery of a "Ring of Dark Matter" in the galaxy cluster CL 0024+17, see Jee M.J. {it et al.} arXiv:0705.2171, based upon gravitational lensing data. Here we show that the lensing can be given an alternative explanation that does not involve "dark matter". This explanation comes from the new dynamics of 3-space. This dynamics...

The anisotropy of the speed of light at 1 part in 10^3 has been detected by Michelson and Morley (1887), Miller (1925/26), Illingworth (1927), Joos (1930), Jaseja et al. (1964), Torr and Kolen (1984), De Witte (1991) and Cahill (2006) using a variety of experimental techniques, from gas-mode Michelson interferometers (with the relativistic theory f...

Full-text available
There are now at least eight experiments extending over more than 100 years that have detected the anisotropy of the speed of light, implying the absolute motion of the detecting apparatus through a dynamical space. This light-speed anisotropy is consistent with relativistic effects and Lorentz symmetry, contrary to prevailing beliefs in physics. T...

In 1991 Roland De Witte carried out an experiment in Brussels in which variations in the one-way speed of RF waves through a coaxial cable were recorded over 178 days. The data from this experiment shows that De Witte had detected absolute motion of the earth through space, as had six earlier experiments, beginning with the Michelson-Morley experim...

The new dynamical theory of space is further confirmed by showing that the effective "black hole" masses M in 19 spherical star systems, from globular clusters to galaxies, with masses M, satisfy the prediction that M = alpha/2M, where alpha is the fine structure constant. As well the necessary and unique generalisations of the Schroedinger and Dir...

A theory of 3-space explains the phenomenon of gravity as arising from the time-dependence and inhomogeneity of the differential flow of this 3-space. The emergent theory of gravity has two gravitational constants: GN — Newton’s constant, and a dimensionless constant α. Various experiments and astronomical observations have shown that α is the fine...

The new dynamical “quantum foam” theory of 3-space is described at the classical level by a velocity field. This has been repeatedly detected and for which the dynamical equations are now established. These equations predict 3-space “gravitational wave” effects, and these have been observed, and the 1991 DeWitte data is analysed to reveal the fract...

The Gravity Probe B (GP-B) satellite experiment will measure the precession of on-board gyroscopes to extraordinary accuracy. Such precessions are predicted by General Relativity (GR), and one component of this precession is the "frame-dragging" or Lense-Thirring effect, which is caused by the rotation of the Earth. A new theory of gravity, which p...

Full-text available
Physics textbooks assert that in the famous interferometer 1887 experiment to detect absolute motion Michelson and Morley saw no rotation-induced fringe shifts — the signature of absolute motion; it was a null experiment. However this is incorrect. Their published data revealed to them the expected fringe shifts, but that data gave a speed of some...

Supermassive black holes have been discovered at the centers of galaxies, and also in globular clusters. The data shows correlations between the black hole mass and the elliptical galaxy mass or globular cluster mass. It is shown that this correlation is accurately predicted by a theory of gravity which includes the new dynamics of self-interacting...

In 1990 Alcubierre, within the General Relativity model for space-time, proposed a scenario for `warp drive' faster than light travel, in which objects would achieve such speeds by actually being stationary within a bubble of space which itself was moving through space, the idea being that the speed of the bubble was not itself limited by the speed...

We further deconstruct Heraclitean Quantum Systems giving a model for a universe using pregeometric notions in which the end-game problem is overcome by means of self-referential noise. The model displays self-organisation with the emergence of 3-space and time. The time phenomenon is richer than the present geometric modelling.

That the speed of light is always c=300,000km/s relative to any observer in nonaccelerating motion is one of the foundational concepts of physics. Experimentally this was supposed to have been first revealed by the 1887 Michelson-Morley experiment, and was made one of Einstein's key postulates of Special Relativity in 1905. However in 2002 the actu...

Full-text available
The Einstein postulates assert an invariance of the propagation speed of light in vacuum for any observer, and which amounts to a presumed absence of any preferred frame. The postulates appear to be directly linked to relativistic effects which emerge from Einstein's Special Theory of Relativity, which is based upon the concept of a flat spacetime...

The new `quantum-foam in-flow' theory of gravity has explained numerous so-called gravitational anomalies, particularly the `dark matter' effect which is now seen to be a dynamical effect of space itself, and whose strength is determined by the fine structure constant, and not by Newton's gravitational constant G. Here we show an experimentally sig...

Full-text available
The galactic `dark matter' effect is regarded as one of the major problems in fundamental physics. Here it is explained as a self-interaction dynamical effect of space itself, and so is not caused by an unknown form of matter. Because it was based on Kepler's Laws for the motion of the planets in the solar system the Newtonian theory of gravity was...

Gravitational anomalies such as the mine/borehole g anomaly, the near-flatness of the spiral galaxy rotation-velocity curves, currently interpreted as a `dark matter' effect, the absence of that effect in ordinary elliptical galaxies, and the ongoing problems in accurately determining Newton's gravitational constant G_N are explained by a generalis...

The new information-theoretic Process Physics has shown that space is a quantum foam system with gravity being, in effect, an inhomogeneous in-flow of the quantum foam into matter. The theory predicts that absolute motion with respect to this system should be observable, and it is shown here that absolute motion has been detected in at least seven...

It is shown that a new quantum-foam in-flow theory of gravity is mathematically equivalent to the General Relativity theory of gravity for the operation of the Global Positioning System (GPS).

We report a re-analysis of the old results from the Michelson-Morley interferometer experiments that were designed to detect absolute motion. We build upon a recent (1998) re-analysis of the original data by Munera, which revealed small but significant effects after allowing for several systematic errors in the original analyses. The further re-ana...

Progress in the new information-theoretic process physics is reported in which the link to the phenomenology of general relativity is made.

Generalising results from Gödel and Chaitin in mathematics suggest that self-referential systems contain intrinsic randomness.

Noise is often used in the study of open systems, such as in classical Brownian motion and in Quantum Dynamics, to model the influence of the environment.

The Global Colour Model (GCM) of QCD is a quark-gluon quantum field theory that very successfully models QCD for low energy hadronic processes. An effective gluon correlator models the interaction between quark currents. Functional integral calculus allows the GCM to be hadronised (i.e. expressed in terms of meson and baryon fields). The dominant c...

The Global Colour Model of QCD is used in conjunction with a pure-gluon lattice correlator (by Marenzoni et al.) to extract from meson data a momentum-dependent quark-gluon coupling down to $s \approx 0.3 GeV^2$. This is compared with a lattice calculation (by Skullerud) of the quark-gluon coupling.

We report results for ρ−ω mass splitting and mixing obtained from a QCD‐based field theory model applied up to the level of one pion loop. The pion loop correction is found to be too small to match ρ−ω mixing with the successful phenomenology for the charge symmetry breaking (CSB) NN force, but does yield excellent results for the ρ width and ρ−ω m...

Two quark propagators with different analytic structure are employed in Bethe-Salpeter type equations for the pion and scalar diquark form factors. One of the quark propagators has been calculated with the inclusion of a trivial (bare) quark-gluon vertex and, as a consequence, contains a complex conjugate pair of logarithmic branch points. The othe...

A model field theory, in which the interaction between quarks is mediated by dressed vector boson exchange, is used to analyse the pionic sector of QCD.

An approximate Schwinger-Dyson equation for the quark propagator in Euclidean QCD is solved numerically in the complex s=p2 plane, where pμ is the quark Euclidean four-momentum.

A review is given of progress in deriving the effective action for hadronic physics, , from the fundamental defining action of QCD, .

The electromagnetic self-energy of charged particles has remained a problem in classical as well as in quantum electrodynamics. In contrast here, in a review of the analysis of the chromodynamic self-energy of quarks in quantum chromodynamics (QCD), we see that the quark self-energy is a finite and a dominant effect in determining the structure of...

Results from a numerical study of the QCD Schwinger-Dyson (SD) equation indicate that the Wick rotation may be disallowed due to the presence of complex branch points in the quark propagator.
