Cosmic Scars: A Topological Theory of Gravity (Final Version)
This work proposes dark matter (DM) and dark energy (DE) as emergent effects of fossilized Weyl curvature defects—cosmic scars—from primordial black holes and Pop III supernovae.
Key breakthroughs:
- Replaces DM/DE without particles via spacetime topology (Eqs. 1-31).
- Predicts JWST galaxy spin alignment (3.1σ), LISA 10−5 Hz gravitational waves, and CMB Cold Spot as Gpc-scale scar.
- Solves NGC 1052-DF2 kinematics, Bullet Cluster offsets, and Hubble tension via differential expansion.

Recent studies of galaxy rotation directions in the distant universe have confirmed the observed trend for an asymmetry of up to 50% more counter rotating galaxies than co rotating galaxies. In that there appear to be more galaxies that rotate counter to our Milky Way than with it. These observations are currently not consistent with the Big Bang theory. And suggests new models of the physics of galaxy rotations may be necessary. Here it is proposed one can use the differing amounts of aberration of light from co and counter rotating galaxies to explain this apparent asymmetry. In that light from co rotating galaxies arrives at the earth observer more dispersed or blurred than light from counter rotating galaxies. Making the rotation direction of co rotating galaxies harder to identify. And in turn creating an asymmetrical bias in the identification between co and counter rotating galaxies. A counter rotating galaxy will appear more sharply in focus and more easily identifiable than the more blurred co rotating galaxy at any similar redshift. And that this asymmetrical bias due to aberration and the relative differences in incident angles between light from co and counter rotating galaxies increases with higher redshifts.

In a recently published paper entitled "Can Rotation Solve the Hubble Puzzle?", the authors claim that the Hubble puzzle can be solved if, in addition to its expansion the universe is also slowly rotating. I have a hypothesis entitled The Pivot Universe that claims that the entire universe is slowly rotating, but contrary to the recent paper it is not expanding.

It is shown that at the present stage of the evolution of the universe, cosmological acceleration is an inevitable {bf kinematical} consequence of quantum theory in semiclassical approximation. Quantum theory does not involve such classical concepts as Minkowski or de Sitter spaces. In classical theory, when choosing Minkowski space, a vacuum catastrophe occurs, while when choosing de Sitter space, the value of the cosmological constant can be arbitrary. On the contrary, in quantum theory there are no uncertainties in view of the following: 1) the de Sitter algebra is the most general ten-dimensional Lie algebra; 2) the Poincare algebra is a special degenerate case of the de Sitter algebra in the limit $Rtoinfty$ where $R$ is the contraction parameter for the transition from the de Sitter to the Poincare algebra and $R$ has nothing to do with the radius of de Sitter space; 3) $R$ is fundamental to the same extent as $c$ and $hbar$: $c$ is the contraction parameter for the transition from the Poincare to the Galilean algebra and $hbar$ is the contraction parameter for the transition from quantum to classical theory; 4) as a consequence, the question (why the quantities $(c,hbar,R$) have the valueswhich they actually have) does not arise. The solution to the problem of cosmological acceleration follows from results on irreducible representations of the de Sitter algebra. This solution is free of uncertainties and does not involve dark energy, quintessence and other exotic mechanisms the physical meaning of which is a mystery.

The MOND theory (Modified Newtonian Dynamics) initiated by Milgrom has established itself as the most important model for explaining the measured rotation curves of galaxies without the aid of ominous dark matter. The core element of MOND is the so-called fundamental acceleration a0 with a value of approx. 1.2⋅10^-10 m/s^2, which results from the measurements of galaxy rotation velocities. At accelerations close to or below this value, neither Newton's nor Einstein's gravitational models work reliably.Critics of the MOND theory argue that this value is an ad-hoc "fudge factor" that was not derived from a fundamental consideration of space and time. So Milgrom himself as well as other proponents of MOND have already shown that the value a0 can very easily be brought into a numerical relationship with the age of the universe Tu and the speed of light c. In this paper, I would now like to show that this numerical correlation is no coincidence, but can be derived by consistent application of Heisenberg's energy-time uncertainty relation on a cosmic scale. So I will show that a0=c/(2π⋅Tu) is the smallest possible acceleration for any rotation/orbital motion in an universe of age Tu and therefore not a "fudge factor", but the counterpart of the Planck acceleration at the other, lower bound of the energy scale with which our universe can be described.

One of the problems of Big Bang cosmology is necessity to explain the events at the beginning of time (soon after Big Bang) as taking place at very high rate (very fast development of the mature galaxies with high metal content, very big black holes, too many galaxies etc). This is because the Plank’s temperature of cooled light (measured at ~2.7 K) may only be what it is measured if the expansion rate corresponds to 13.6 billions of years for total age. Since James Webb already reached z=14 (corresponding to 13.4 billions of years back in time) almost no time is left for normal, slow as we observed in nearby cosmos rate of galaxies and black holes etc formation. Big Bang theory can not "move" this time threshold further in time (accepting this would be suicide for Big Bang because it means the light itself may somehow be thermalized and red shifted according to tired light theory). Thus Big Bang theorists are inventing numerous "epicycles" like primordial black holes, black dark matter, even unification of Big Bang and tired light [1] - all in attempts to either accelerate the processes in the very beginning or move age of Universe further (say up to 27 billions of years [1]) to allow slow and well known growth of galaxies. The contradiction easily observed in James Webb Space Telescope images is discussed here - and it also because of the presence of this ~13 billions of years time boundary condition — in Big Bang cosmology the geometrical distance (what determines the optical resolution) to the galaxies with Z=8 and Z=14 is around 13 billions of light years with very high accuracy (13.1 billions of light years to z=8 objects and 13.4 billions of light years for Z=14 objects). From astronomy point of view the angular resolution of such objects is the same — yet at Z=8 galaxies are mainly ovals (as expected for poorly resolved objects) while at z=12-14 they are unresolved circles (which is not possible in either developed galaxies or so called primordial fast merging galaxies — in both cases ovals would be observed for poorly resolved galaxies). Such simple images like dots or circles hints onto the much further distance to the observed record breaking galaxies, where even JWST angular resolution is not enough to resolve at least something.

This paper explores the concept of real virtual annihilation in quantum spacetime, emphasizing theinteractions between real and virtual particles. Through theoretical formulations and quantum field dynamics, the study delves into the formation of black holes, quantum invariance under gravity, and the profound relationship between uncertainty principles and Minkowski metrics.

Based on multiple astronomical observation results, this paper proposes the hypothesis of the principle of relative variation of the speed of light and proves the compatibility between this principle and the principle of the constancy of the speed of light. Based on this principle, this paper constructs an innovative theoretical framework of the vacuum dynamics theory and derives several important conclusions.

Dark matter, a fundamental component of the universe, remains one of the most fascinating mysteries in modern astrophysics. Despite its pervasive influence on the dynamics of the universe, its elusive nature continues to challenge the understanding of fundamental physics. This comprehensive review synthesizes recent research findings, theoretical frameworks, observational evidence, and experimental efforts in the quest to understand the nature and properties of dark matter.
