“…The contention that the Universe is oriented around a major axis shifts from the standard cosmological models. It might be in agreement with other theories such as ellipsoidal universe (Campanelli et al, 2006;Gruppuso, 2007), rotating Universe (Gödel, 1949;Ozsváth and Schücking, 1962;Ozsvath and Schücking, 2001), and black hole cosmology (Pathria, 1972;Stuckey, 1994;Easson and Brandenberger, 2001;Seshavatharam, 2010;Pop lawski, 2010b;Christillin, 2014;Dymnikova, 2019;Chakrabarty et al, 2020;Pop lawski, 2021;Seshavatharam and Lakshminarayana, 2022;Gaztanaga, 2022a,b), which assume the existence of a cosmological-scale axis, but it is not aligned with the standard model. On the other hand, it is also possible that the Universe does not have a cosmological-scale axis, and the observed asymmetry is driven by internal structure of galaxies (Shamir, 2020a;.…”

“…One of the cosmological models aligned with the contention that the Universe is oriented around a large-scale axis is black hole cosmology (Pathria, 1972), according which the Universe is the interior of a black hole in another universe (Pathria, 1972;Stuckey, 1994;Easson and Brandenberger, 2001;Seshavatharam, 2010;Pop lawski, 2010b;Tatum et al, 2018;Christillin, 2014;Chakrabarty et al, 2020). Since black holes spin (Gammie et al, 2004;Takahashi, 2004;Volonteri et al, 2005;McClintock et al, 2006;Mudambi et al, 2020;Reynolds, 2021), a universe hosted inside a black hole should inherit its spin from its host black hole (Pop lawski, 2010a;Seshavatharam, 2010;Seshavatharam and Lakshminarayana, 2014;Christillin, 2014;Seshavatharam and Lakshminarayana, 2020b,a).…”

Using 3D and 2D analysis for analyzing large-scale asymmetry in galaxy spin directions

The nature of galaxy spin is still not fully known. Iye, Yagi, and Fukumoto (2021, AJ, 907, 123) applied a 3D analysis to a dataset of bright SDSS galaxies that was used in the past for photometric analysis. They showed that the distribution of spin directions of spiral galaxies is random, providing a dipole axis with low statistical significance of 0.29σ. However, to show random distribution, two decisions were made, each of which can lead to random distribution regardless of the real distribution of the spin direction of galaxies. The first decision was to limit the dataset arbitrarily to z < 0.1, which is a redshift range in which previous literature already showed that random distribution is expected. More importantly, while the 3D analysis requires the redshift of each galaxy, the analysis was done with the photometric redshift. If the asymmetry existed, its signal is expected to be an order of magnitude weaker than the error of the photometric redshift, and therefore a low statistical signal under these conditions is expected. When using the exact same data without limiting to zphot < 0.1 and without using the photometric redshift, the distribution of the spin directions in that dataset shows a statistical signal of >2σ. Code and data for reproducing the analysis are publicly available. These results are in agreement with other experiments with SDSS, Pan-STARRS, HST, and the DESI Legacy Survey. The paper also examines other previous studies that showed random distribution in galaxy spin directions. While further research will be required, the current evidence suggests that large-scale asymmetry between the number of clockwise and counterclockwise galaxies cannot be ruled out.

“…For example, the Hubble parameter determined from the cosmic microwave background (CMB) radiation differs from that determined using Type Ia supernovae and the redshift of their host galaxies [33,36,37]. While one possible explanation is the incompleteness of the concordance model, alternative theories propose that the standard redshift model, as a distance-scale factor relation, might be incomplete [38]. Addressing these observations supports modifications to some foundations of cosmology based on the cosmological principle [39].…”

This paper explores the fundamental cosmological principle, with a specific focus on the homogeneity and isotropy assumptions inherent in the Friedmann model that underpins the standard model. We propose a modified redshift model that is based on the spatial distribution of luminous matter, examining three key astronomical quantities: light intensity, number density, and the redshift of galaxies. Our analysis suggests that the model can account for cosmic accelerated expansion without the need for dark energy in the equations. Both simulations and analytical solutions reveal a unique pattern in the formation and evolution of cosmic structures, particularly in galaxy formation. This pattern shows a significant burst of activity between redshifts 0 < z < 0.4, which then progresses rapidly until approximately z ≈ 0.9, indicating that the majority of cosmic structures were formed during this period. Subsequently, the process slows down considerably, reaching a nearly constant rate until around z ≈ 1.6, after which a gradual decline begins. We also observe a distinctive redshift transition around z ≈ 0.9 before the onset of dark-matter-induced accelerated expansion. This transition is directly related to the matter density and is dependent on the geometry of the universe. The model’s ability to explain cosmic acceleration without requiring fine tuning of the cosmological constant highlights its novelty, providing a fresh perspective on the dynamic evolution of the universe.

“…Furthermore, Lorentz 2 transformations describe how the motion changes in a moving reference system compared to a fixed one. Space-time could be composed of X particles 3 emit energy 4 . In fact, recent research describes the expansion speed of the universe 5 as 67360 m/s/mp.…”

Dark matter and dark energy don’t absorb light and don’t reflect light. They’re transparent in the universe. In the universe there are transparent materials and energies but they’re all part of the ordinary matter of the universe. Only Einstein's Space-Time could have its own mass and energy. Einstein's space-time may have its own expansion rate. From this speed of expansion of space-time it’s possible to define a momentum. Since momentum is a conserved quantity, it’ll be equal to the momentum relative to the expansion rate of ordinary matter. Therefore, it could be space time that is composed of X particles that pervade the entire universe.
