Short Version of "Turing-Unsimulability & Cosmic-Censorship-Falsity for General Relativity"

Authors: Warren D. Smith
Comments: 6 Pages.

My paper http://vixra.org/abs/2605.0004 "Turing-Unsimulability, and instantaneous & sustained Cosmic-Censorship-falsity, for Einstein-Vacuum General Relativity", at 60, 74, and 78 pages for versions 1, 2, and 3, was too long for many stomachs. Therefore I here also provide a short introductory explanation (in the spirit of Phys.Rev.Letters summaries of fuller papers) of its main ideas to try to advertise it and to get expert readers oriented right before they start.

The Optical Prison: Universal Physical Isolation as the Physical Solution to the Fermi Paradox

Authors: Hao Xu
Comments: 10 Pages. (Note by viXra Admin: Please cite listed scientific reference and submit article written with AI assistance to ai.viXra.org)

An Optical Prison hypothesis is proposed that would physically resolve the Fermi's Paradox. Three independent ground optical experiments verify the physical limitation of the astronomical observations caused by structural self-weight collapse and optical inherent constraints. Unlike conventional SETI concepts, the conclusion is quantitatively restricted by measurable experimental data, lacking empirical support, our conclusion is qualitatively restricted by neutron degradation and explaining the cosmic silence in SETI observations.

Testing the D.M. By Quantum Gravitation Theory by the Mass Associated to the Turnaround Radius

Authors: Manuel Abarca Hernandez
Comments: 9 Pages.

The DM by Quantum Gravitation theory (DMbQG hereafter), is a novel theory developed in the two main papers [1] and [2] Abarca, M. (2024). In the present work, in the framework of DMbQG theory it will derived the formula for the mass associated to the turnaround radius depending on the turnaround radius and it will be shown that the new expression has a deeper physical meaning regarding the same formula in the current ΛCDM paradigm. The DMbQG theory states a direct relation between the virial radius and the turnaround radius as well as the virial mass and the mass associated to the turnaround radius.The most important contribution of this work is placed in the chapter 2 where it has been demonstrated that the formula for the mass associated to the turnaround radius, using the DMbQG theory, is the same that the one in the current ΛCDM paradigm. However the new formula has a deeper physical meaning because its dimensionless factor is simpler regarding the one in the current ΛCDM paradigm. Also it is remarkable the fact that the both dimensionless factors depend on exclusively from Ωm or ΩDE and the both ones differ only a 5%. The fact that in the framework of DMbQG theory has been found a better formula for the mass associated to the turnaround radius is a strong support for the DMbQG theory whose hypothesis about the origin of DM is exclusively the gravitational field. The chapters 3, 4 and 5 are devoted to test the DMbQG theory in the clusters: Virgo, Coma and the Local Group of galaxies using recent data published about these clusters. The tests are mainly focused on the turnaround radius and its mass associated and all of them have been a complete success by the DMbQG theory. In this second version of the paper, the mass associated to the turnaround radius formula is obtained by a different way regarding the first version. In this new method is not used any formulas with the parameter "a", achieving a more understandable process to obtain the same formula.

Gravity as an Emergent Force Via the Uncertainty Principle

Authors: Morgan W. Weinberg
Comments: 51 Pages.

The core concept of this paper is the relation between an accelerating field and time uncertainty. This relation distills from the derivation of Newton's Law of Gravitation via the uncertainty principle. It's shown, further, that this relation can be used to derive the Coulomb Force, suggesting that it may be a general principle in nature. Taking this concept further, this paper draws a connection between expanding space and acceleration---offering an explanation for the missing-mass problem in galaxies. The paper goes on to draw a connection between the expansion of space and time uncertainty, leading to a startling conclusion: The expansion of space is not a function of the energy contained therein, but conversely, the mass of the universe is created in concert with the expansion of space. Further, because this expansion is a function of time, the mass of the universe is a function of time and increases in lockstep therewith. It's deemed that the model of the universe presented herein obviates the need for dark matter and dark energy to explain our observations of the cosmos.

Doppler Effect, Absolute Stellar Aberration, Stellar Velocity, Stellar Distance and Speed of the Light

Authors: Miloš Čojanović
Comments: 6 Pages.

Our assumption is that the Doppler Effect and Absolute Stellar Aberration are two complementary phenomena. This means that if we are able to use the result obtained by measuring $DE$ to determine the radial velocity, then by using the result obtained by measuring "ASA" we should be able to determine the transverse velocity with which the star moves in relation to the observer. We will prove that if we know the velocity of the star, we can determine its distance in relation to the observer and the speed of light emitted from the star in the direction of the observer.

Resolving the Cosmological Hubble Tension via Local Wave Impedance Fluctuations in a Hexagonal Close-Packed Lattice

Authors: Markov Efim Sergeevich

The persistent cosmological discrepancy between early-universe cosmic microwave background (CMB) measurements (H0 approx 67.4 km/s/Mpc) and late-universe local distance ladder observations (H0 approx 73.0 km/s/Mpc) - known as the Hubble Tension - presents a fundamental crisis for the continuous Lambda-CDM paradigm. This paper resolves this conflict by shifting from expanding spacetime metrics to a stationary, non-singular Hexagonal Close-Packed (3HCP) discrete space crystal. We demonstrate that cosmological redshift is not a Doppler-like stretching of space, but a dissipative energy attenuation of electromagnetic wave packets undergoing sub-nodal friction across contacting cellular boundaries. By modeling the material vacuum as a discrete transmission network with a baseline register capacity Llimit = 256, we derive the propagation velocity and local wave impedance purely from first-principles lattice geometry. Through a multivariable Taylor series expansion, we establish a rigorous mathematical bridge proving that our discrete wave difference scheme converges onto the continuous Maxwell equations with a damping term as the lattice spacing approaches zero (h -> 0). Crucially, we show that local structural density fluctuations within the 3HCP matrix systematically alter the sub-nodal impedance along different lines of sight. Low-density intergalactic voids minimize wave friction, yielding an apparent higher local expansion rate (H0 approx 73.0), while deep CMB-scale averaging profiles smooth over macroscopic high-density clusters, converging onto the lower background global baseline (H0 approx 67.4). The Hubble Tension is thus completely eliminated, emerging as a predictable geometric artifact of measuring discrete wave impedance across a multi-scale, non-uniform spatial crystal.Creative Commons Attribution Non Commercial No Derivatives 4.0 International

Big Gravity Remains Elusive

Authors: Clark M. Thomas
Comments: 5 Pages.

Big Gravity’s (G) Newtonian constant for the local universe seems to be something that eludes astrophysicists seeking better numbersfor the claimed four forces. The latest G data have failed to confront the hermeneutical limits of what their experimental tools measure.We need better multiversal causative precision in 4D dimensions, not weak mathematical correlations. Big Gravity, and Earth’s variablesurface gravities (g), include electromagnetism, along with the properly conceived net push/shadow kinetics. Unifying harmony among all physics dimensions is needed for any elegant multiversal paradigm.
