Humans are viewed as a part of nature, a notion of undeniable importance. This notion revolves around the complex relationship between humans and nature, characterized by mutual influence. Nature, in its many manifestations, affects humans physically, mentally, and even psychologically, while humans strive to harness and subdue nature, creating a d...

In early January, an article titled “How a quantum innovation may quash the idea of the multiverse” appeared in New Scientist [1] It received a prompt response from German physicist Sabine Hossenfelder in the form of a video on You Tube [2]. The multiverse part got my attention. Suppose quantum gravity one day goes far beyond unifying quantum mecha...

We propose a dark energy model within the framework of induced gravity, where gravitational dynamics emerge from quantum effects in curved spacetime. The model invokes a scalar field ϕ non-minimally coupled to gravity, leading to an effective cosmological constant. We explore the dynamical evolution of dark energy, discuss stability criteria, and d...

Whitehead's project comes out as a cosmology from the writings that were published until recently, before the availability of the course notes at Harvard. It also comes out as a meditation on cosmic solidarity, beyond the breakdown of syntheses around their submission to “perpetual perishing.” Whitehead always maintained that his philosophy was a “...

Curl lensing, also known as lensing field-rotation or shear B-modes, is a distinct post-Born observable caused by two lensing deflections at different redshifts (lens-lens coupling). For the Cosmic Microwave Background (CMB), the field-rotation is approximately four orders of magnitude smaller than the CMB lensing convergence. Direct detection is t...

In this work, we analyze the cosmological model in which the expansion is driven by a classical, free Klein–Gordon field on a flat, four-dimensional Friedmann–Lemaître—Robertson–Walker spacetime. The model allows for arbitrary mass, non-zero cosmological constant and coupling to curvature. We find that there are strong restrictions to the parameter...

Analyses of the cosmic 21 cm signal are hampered by astrophysical foregrounds that are far stronger than the signal itself. These foregrounds, typically confined to a wedge-shaped region in Fourier space, often necessitate the removal of a vast majority of modes, thereby degrading the quality of the data anisotropically. To address this challenge,...

If primordial scalar or tensor perturbations are enhanced on short scales, it may lead to the production of observable gravitational wave signals. These waves may be sourced by scalar-scalar, scalar-tensor or tensor-tensor interactions. Typically, models of inflation capable of producing large peaks in the scalar primordial power spectrum also gene...

We initiate the study of “bubbletrons,” by which we mean ultrahigh-energy collisions of the particle shells that generically form at the walls of relativistic bubbles in cosmological first-order phase transitions (PT). As an application, we calculate the maximal dark matter mass M DM that bubbletrons can produce in a U ( 1 ) gauge PT, finding M DM...

We investigate the impact of peculiar motion of Type Ia supernova host galaxies on cosmological parameter estimation. This motion causes their redshift to deviate from that of the comoving observer at their position and is a source of noise. To this end, we develop an estimator for parameter estimation in models with errors in independent variables...

Large-scale structure (LSS) studies in cosmology map and analyse matter in the Universe on the largest scales. Understanding LSSs can provide observational support for the cosmological principle (CP) and the standard cosmological model (ΛCDM). In recent years, many discoveries have been made of LSSs that are so large that they become difficult to u...

The standard cosmological model ΛCDM is described by the Friedman–Lemaitre–Robertson–Walker (FLRW) metric, which requires that the universe be isotropic and homogeneous on large scales, an assumption called the Cosmological Principle. If this assumption is accurate, then the dipole anisotropy observed in the cosmic microwave background (CMB) corres...

Calculating the action and the interaction Hamiltonian at higher orders in cosmological perturbation theory is a cumbersome task. We employ the formalism of EFT of inflation in models of single field ultra slow-roll inflation and obtain a non-perturbative result for the Hamiltonian in terms of the Goldstone field $\pi$. To complete the dictionary,...

The standard ΛCDM cosmology passes demanding tests that establish it as a good approximation to reality. It is incomplete, with open questions and anomalies, but the same is true of all our physical theories. The anomalies in the standard cosmology might guide us to an even better theory. It has happened before. This article is part of the discussi...

The cosmological principle demands that the motions of galaxies averaged over a large enough sphere should become small. Thus, the large-scale bulk flow is an important test of this principle and of the standard cosmological model more generally. While hints of anomalous bulk flows have been reported for decades, in the past few years, the quality...

Scaling relations of galaxy clusters are a powerful probe of cosmic isotropy in the late Universe. Owing to their strong cosmological dependence, galaxy cluster scaling relations can obtain tight constraints on the spatial variation of cosmological parameters, such as the Hubble constant (H0), and detect large-scale bulk flow motions. Such tests ar...

Observations of the cosmic microwave background (CMB) radiation are described with remarkable accuracy by the six-parameter ΛCDM cosmology. However, the key ingredients of this model, namely dark matter, dark energy and cosmic inflation are not understood at a fundamental level. It is, therefore, important to investigate tensions between the CMB an...

In this paper, it is shown that $N$naturalness scenarios have an intrinsic mechanism to suppress neutrino masses. As in other infrared neutrino mass models like extra-dimensional theories or many species theories, the large number of mixing partners is responsible for the neutrino mass suppression. It is shown how neutrino mass matrices arise in $N...

In the present work, we study cosmology in dilatonic f(R,T) gravity to address the inflationary phase of the early universe. As usual, in dilatonic gravity, the scalar potential assumes the exponential form. However, this potential is not good enough to be in accordance with the Planck 2018 data. More strikingly, the generalized β-exponential canno...

Unimodular gravity (UG) is classically considered identical to General Relativity (GR). However, due to restricted diffeomorphism symmetry, the Bianchi identites do not lead to the conservation of energy-momentum tensor. Thus, the conservation of energy-momentum tensor needs to be separately assumed in order to reconcile with GR. Relaxing this assu...

In this article, it is argued that the solutions to some of the problems we face in cosmology may not require new physical theories as much as they require a time symmetric perspective. The Principle of Least Action is nowadays mostly used as a convenient tool for deriving the field equations. It is suggested that new insights could be obtained by...

We study the cosmological impact of warm, dark-sector relic particles produced as Hawking radiation in a primordial-black-hole-dominated universe before big bang nucleosynthesis. If these dark-sector particles are stable, they would survive to the present day as Hawking relics and modify the growth of cosmological structure. We show that such relic...

The ineffable sensation and certainty of “unity” (The Real) is rationalized in the logos of Heraclitus, a philosopher wrongly called “The Dark One of Ephesus”, since neither contradictory (Najmanovich, 2008) nor cryptic, as a wise man in these times of uncertainty and “Baumanian liquidity” it allows us to “re-think our experience of the world” (Agu...
