The anomalous alignment between the CMB quadrupole and octopole, that they are jointly perpendicular to the ecliptic plane, and also aligned with the direction of the solar dipole near to the equinoxes are up to now unsolved conundrums. The preferred axis in the cosmic radiation anisotropy and the alignments were dubbed "axis of evil" (Land & Magueijo, 2005), and are the most prominent of the CMB anomalies. It is standard that the 1st order term of the dipole formula essentially represents a motion induced Doppler temperature pattern against the isotropic Planckian radiation field. We argue that the Doppler term is entirely a function of the peculiar velocity of the Planck space telescope in the CMB rest-frame (CMB-space).In two recent publications of us we have found solutions to the flyby anomalies and to the residual annual and diurnal P 10 signal variations on top of the resolved P 10 acceleration anomaly, using the peculiar velocity of Earth and the peculiar velocities of the involved space probes in the CMB-space. That two independent solutions are corroborating our assertion that the quadrupolar and octopolar terms, following from the 2nd order term in β = v/c expanding of the dipole formula, are not "relativistic corrections to the solar dipole, producing second order anisotropies at multipoles l ≥ 1, with amplitudes proportional to βl, and more importantly couple the two dipole components" (Planck Collaboration, 2015).Instead, the 2nd order term of the dipole formula, the inverse γ - factor, represents solely the annual eigen-frequency oscillations of the Planck HFI, proportional to the annual eigen-time variations in the fundamental CMB-space, as a function of the peculiar velocity of the Planck space telescope, leading to a solution of the only seemingly anomalous alignments.

There are stellar-mass black holes (SBHs), andthere are supermassive (SMBHs). Little theory hasdeveloped to explain if or how intermediate-massblack holes (IMBHs) may be clearly distinct fromeither type. How then do IMBHs exist? RecentHubble and JWST data on Omega Centauri pointtoward a better theory of formation. A surprisinginsight into the 4D multiverse also emerges.

I argue that the JWST findings on early galaxies, along with other discrepancies such as Hubble’s constant tension, cast serious doubt on the validity of the Big Bang theory. The first JWST findings regarding early galaxies were observed only two years ago. These findings are not consistent with the Big Bang theory (BB), which posits that as we look back in time towards the Big Bang, early galaxies should appear small and underdeveloped because there hadn't been enough time for them to evolve. However, the JWST findings have shown the opposite. Early galaxies (approximately 400 million years after the Big Bang) appear fully developed, similar to galaxies like the Milky Way, which is estimated to be around 13.6 billion years old. Some scientists have questioned the validity of the Big Bang theory; however, many are hesitant to dismiss it based on these findings. They argue that our understanding of galaxy formation in the early universe requires refinement. As research continues and new early galaxies are observed, the initial finding that galaxies appear fully developed persists, regardless of the time elapsed since the Big Bang.I suggest here an alternative model of the universe, I designate the Pivot universe, that explains the JWST finding on early galaxies.

The James Webb space telescope reveals much earlier and bigger galaxies than we expected, indicating inadequacies in our current understanding of the universe. This paper reviews the current practice in estimating the age of the universe and uncovers a problem: the luminosity distance is incorrectly related to the proper distance. This mistake causes the underestimation of the comoving distance, and thus of the expansion and the age of the universe. By linking the luminosity distance to the light travel distance, this paper provides a rectified formula for estimating the age of the universe.

The significant difference of the Hubble constant value estimated from the local distance ladder and from the cosmic microwave background radiation attracts substantial attention in the recent decade and has been dubbed as Hubble tension. Many researchers set out to find the source of Hubble tension, e.g. identifying the possible errors in distance estimation and exploring new theories or physical causes to fix the possible problems in the ΛCDM model. However, the tension is still unresolved. This paper examines the process of converting redshift to recessional velocity and reveals that the converting formula for local estimations is inappropriately approximated. By using the relativistic Doppler effect formula, the paper reduces the estimated Hubble constant from Cepheid method by 6%, agreeing with the estimates from the CMB method at about 1σ level. It is expected that the right formula can bring the estimates from the TRGB method to the same level of the CMB estimates, so the Hubble tension should disappear.

There is a crisis with the standard model of cosmology at its outer limits. Why are well-developed galaxies, observed by the James Webb Space Telescope, existing only 300 million years from the beginning of the observable universe? A solution to the problem is offered that evokes the principles laid down in Albert Einstein's 1905 special relativity, time dilation. Are we looking at a wall where time stops? Special relativity states that time slows down if you’re moving — relative to an observer. As a body approaches the speed of light, time will appear to slow on the moving /travelling body. At the speed of light time will appear to stop to the observer. The solution is we are the observers and the galaxies (relative to us) at the outer edge of the universe— right about the place of the said Big Bang beginning — are expanding away from us at the speed of light and faster. We are observing a wall where time stops, a barrier, that we cannot see through. This would suggest the universe can be much older and we may never know how old because of this barrier. Special relativity also says that bodies appear smaller from the perspective of the observer. This may further distort our perception of the accelerating universe; the universe may be even larger than thought.

Based on Newton’s gravitational law as applied to a uniform continuous mass we posit a non-homogeneous distribution of mass at cosmological scales that would give rise to a constant acceleration that largely agrees with MOND’s a0. When mass-density distributes as 1/R in a spherically symmetric universe, rotational velocities arise that increase as the square root of radial distance. These would generate a transverse Doppler redshift that scales linearly with distance at short ranges and would mimic cosmological redshift and expansion. In the more distant regions, relativistic-high rotational velocities result in a highly redshifted background radiation that might distort the estimation of distances based on Hubble’s Law. These phenomena might provide an alternative explanation for the observed redshifts and expansion.

This comprehensive work, structured into thirteen sections, delves into the Variable Speed of Light (VSL) hypothesis, offering an innovative framework for understanding cosmological phenomena. The introduction and prologue set the stage by addressing the motivations behind VSL and the misinterpretations of Einstein's second postulate. While Einstein posited that the speed of light in a vacuum, 'c,' must be determined experimentally, this has been misinterpreted to mean that 'c' is universally constant under all conditions. Instead, this work argues that 'c' might locally vary based on the properties of each specific vacuum, challenging the notion of a true-vacuum and suggesting it behaves more like a low-density medium rather than completely empty space.Section 1 explores the relationship between permittivity, permeability, and VSL, laying the groundwork for understanding how changes in vacuum properties could affect light speed. Section 2 examines the vacuum itself, proposing that its characteristics can influence 'c' and thus impact our understanding of space and time. Section 3 extends this by discussing different types of media within the vacuum and their potential effects on light speed.Section 4 analyzes the implications of considering the speed of light as locally constant rather than universally fixed, which could lead to significant revisions in both Special and General Relativity. Section 5 compares VSL with the traditional inflationary model, suggesting that VSL could provide alternative explanations for the early universe's rapid expansion. Section 6 addresses the Hubble Tension, exploring how VSL could reconcile discrepancies in measurements of the Hubble constant.Sections 7 and 8 discuss the practicalities of implementing VSL and propose experiments and observations to test its predictions. Section 9 focuses on empirical verification, emphasizing the need for robust observational data to validate the VSL hypothesis. Section 10 presents a mathematical model for VSL, highlighting its potential to reshape our understanding of the universe's expansion.The final conclusions summarize the key findings, stressing the importance of further investigation and experimental verification. This work aims to challenge established concepts, suggesting that VSL could provide new insights into cosmology and urging the scientific community to explore this hypothesis more deeply.
