Dark Matter is the Negative Entropy Force Brought by the Cosmic Expansion

Authors: Xiao Lin Li
Comments: 9 Pages.

Particles in quantum mechanics have the property of quantum wave entropy. Similar to stretching a spring, under the specific conditions of cosmic expansion, particle wave entropy exhibits a negative entropy force that resists expansion. This negative entropy force provides particles with an attractive effect different from gravity. Like a spring constant, the negative entropy force has a proportional factor. The negative entropy force is proportional to the Hubble constant and also proportional to gravitational rotational speed. The effect of this negative entropy force is roughly the same as that of dark matter, serving as the physical origin of dark matter effects. Negative entropy force leads to a result where the rotation speed of a galaxy is proportional to the fourth root of the distance, showing an approximately flat and slowly rising curve. Negative entropy force also can explain the Tully-Fisher relation. Galaxies have properties of a flat radius and a cutoff radius. Galaxies only show noticeable dark matter effects within a limited range. The dark matter effect becomes noticeable starting from the flat radius and begins to decline noticeably from the cutoff radius. The flat radius and cutoff radius of a galaxy are determined by its mass. Galaxies of different masses and sizes will show different behaviors of dark matter. Negative entropy force also applies to photons and can explain the dark matter effects in gravitational lensing. Therefore, without assuming the existence of dark matter or modifying gravity theory, we can still normally explain the observed dark matter phenomena in galaxies. Dark matter doesn't exist, and MOND isn't needed.

Mars will Not be Settled

Authors: Volker W. Thürey
Comments: 5 Pages.

Many people dream of establishing a settlement on the planet Mars, especially the American entrepreneur Elon Musk. However, I believe this is nearly impossible because of the planet's extremely harsh environmental conditions. Compared with Mars, Earth is far more hospitable to human life.

Finite-Time Transport Boundaries and Family-Constrained Robustness in the Earth—Moon CR3BP

Authors: Ayush Samanta
Comments: 37 Pages.

Finite-time transport in the circular restricted three-body problem (CR3BP) can change qualitatively under perturbations to initial conditions, making robustness difficult to characterize using smooth trajectory sensitivities alone. This work investigates whether geometric distance to an outcome-change boundary can provide a usefulmeasure of transport robustness for a two dimensional family of invariant-manifold seeds generated from planar L1 Lyapunov orbits in the Earth—Moon CR3BP. A 160 × 33 parameter atlas comprising 5280 initial conditions was classified by first-passage outcome, and adaptive refinement produced 484 numerical samples of the resultingoutcome boundaries. To avoid arbitrary Euclidean distance in the family parameters, the seed-state map was used to induce a local pullback metric, defining a family-constrained boundary-distance diagnostic ρη. The metric construction was numerically consistent, and ρη revealed strongly nonuniform proximity to the resolved transportinterfaces. Its ordering, however, depended on the prescribed state weighting, with Spearman correlations ranging from approximately 0.794 to 0.999 across the tested metrics. Direct perturbation tests also rejected a guaranteed-radius interpretation: one outcome change occurred at approximately 0.5ρη, while finite directional searches at five representative points recovered no independent minimum flip distance. These results support ρη as a family- constrained geometric diagnostic of proximity to resolved finite-time outcome boundaries, but not as a certifiedoutcome-preserving radius or validated transport condition number. A stronger robustness measure requires converged boundary resolution, physically specified uncertainty geometry, and direct computation of minimum outcome-changing perturbations.

A Comparative Analysis of Classical Escape Velocities and Minkowski Metric Compression in Supermassive Horizon Geometries

Authors: Jacqueline Fernandes
Comments: 4 Pages.

This paper explores the transition boundary where classical escape velocity thresholds intersectwith relativistic coordinate transformations. Using observational mass configurations from Sagittarius A*, we analyze how super luminal escape velocities (ve > c) force a geometric inversion ofthe local Minkowski metric tensor. We demonstrate that the information loss paradox is fundamentally a consequence of the future light cone compressing and tilting past the vertical axis, renderingoutward spatial paths geometrically non-existent to an external observer.

Continuous Modulated Waves from Jupiter. A Possible Signature of Rotating Shells with Distinct Periods Inside Jupiter

Authors: Herbert Weidner
Comments: 10 Pages.

We report the detection of continuous microhertz waves originating from Jupiter, recovered from two decades of atmospheric pressure measurements across Germany. Barometers act as largeu2011aperture antennas for lowu2011frequency signals, allowing coherent recovery of a carrier near 55.97 $mu$Hz, which corresponds to twice the rotation frequency of Jupiter’s solid core. A directu2011conversion receiver iteratively compensates all known phase modulations caused by Earth’s orbit and the four Galilean moons, concentrating the wave’s energy into a narrow spectral line with a signalu2011tou2011noise ratio of 100. We measure the longu2011term frequency drift of Jupiter’s core and determine the modulation indices associated with each moon. The phaseu2011modulation pattern is stable across 318 independent realizations. Additional spectral features indicate that Jupiter hosts multiple internal oscillators with distinct frequencies. These results demonstrate that Earth’s atmosphere responds coherently to microhertz waves generated by nearby planets.

Where Are the "Earth-like Planets"? On the Predictive Power of Geometrodynamic Models

Authors: Anatoly V. Belyakov
Comments: 10 Pages. 4 Fig.

Physical models based on J. Wheeler’s geometrodynamics, when applied to planetarysystems and pulsars, agree well with modern observational results and predict new ones.The current geometrodynamic model explains the appearance of the "hot Neptunian desert"region, the existence of an "airy super-Earth", the construction of compiled pulsar spectra,the calculation of their "death line", the calculation of braking indices for various pulsarpopulations, and much more.
