We consider an alternative approach to the gravitational singularity problem by treatingthe core of a black hole as a saturated state with a finite density bound. In classical GeneralRelativity, the metric diverges at r = 0, leading to infinite density and a breakdown of thefield equations. In this paper, we replace this divergence by introducing a maximum densitylimit locked to the invariant Planck density (ρmax). By matching an internal de Sittergeometry to an external Schwarzschild metric, we find that the collapsed core stabilizes as afinite object. Evaluating this matching condition across primordial, stellar, and galactic massscales indicates that the core volume scales dynamically (V ̸= 0) to maintain the densityplateau. This geometric mechanism offers a direct way to connect macroscopic gravity withdiscrete quantum limits.

We consider an effective gravitational potential whose extra term is a regularised two-dimensional logarithmic potential — the logarithmic Green''s function of the two-dimensional Poisson equation. We derive its source surface density, Σ(R) ∝ rc^2/[(R^2 + rc^2)^2] (a two-dimensional Plummer-like distribution), and show that its total mass satisfies M = Vflat^2/G2 exactly, so that the model has a well-defined physical normalisation. The circular-velocity contribution is V2D^2(R) = Vflat^2 R^2/(R^2 + rc^2), which differs from a pseudo-isothermal (PI) halo in the approach to the flat asymptote (1/R^2 vs. 1/R corrections). We fit this model, MOND (two interpolating functions), NFW, PI and Burkert halos to the SPARC sample of 175 disk galaxies (3391 velocity measurements), with the stellar mass-to-light ratio free per galaxy and a systematic error floor scanned over 0—15%. At the reference 10% floor, the cored models give lower total χ^2 than NFW and both MOND forms: χ^2/N = 0.57 (2D), 0.57 (Burkert), 0.60 (PI), versus 0.79 (NFW), 1.38 (MOND-simple) and 1.66 (MOND-standard). The three cored models (2D, Burkert, PI) have similar goodness of fit, but the information criteria moderately favour the 2D model over PI (∆AIC ≃ 93) and provide only a modest preference over Burkert (∆AIC ≃ 13); the present data do not establish a decisive physical distinction among them. The discriminating observable is the shape of the transition to the flat asymptote: 1/R^2 for the 2D potential, 1/R for PI, and a peak followed by a slow decline for Burkert. We show that SPARC covers the relevant radial range only partially (23% of data points in the discrimination zone). Against MOND the result depends on the model-selection criterion, because MOND has substantially fewer global parameters. Among the models evaluated at each error-floor value, the 2D model gives the lowest total χ^2; MOND-standard is evaluated only at the reference 10% floor. We conclude that the soft-logarithmic potential is a viable, normalised member of the cored-model family, with a specific falsifiable prediction for the transition region.

We present here elements which validate the identification of what is called "dark matter" to the classical gravitational energy. The corpuscular gravitation theory [1],[2] gives a very concrete interpretation to this energy which concerns the space void of all known matters, black holes and radiation. Measuring the energy density of the vacuum by the Casimir effect may be an experimental verification.

Almost all observations clearly show the condensed matter nature of the Sun. Regrettably, empirical solar data are always interpreted with the Standard Solar Model (SSM) in mind. Basically, the interpretation of solar features and phenomena must be compatible with the SSM. For instance, sunspots, granules, and faculae are regarded as optical illusions within a gaseous mass, yet they are actually real physical structures formed by condensed crystal lattices. Besides that, the Sun’s average density (1.41g /cm^3) —which is comparable to Earth's oceans and slightly denser than water—is ignored or rather deliberately misinterpreted by being considered a mathematical illusion. In fact, not only is the overall density of the Sun perfectly aligned with the condensed liquid state, but pure gases of this composition would also not inherently maintain the observed structural rigidity required for the solar dynamo to operate. Moreover, a continuous solar spectrum cannot be produced by gaseous bodies. That is because a continuous spectrum requires dense, opaque matter (like solids or liquids) in order to emit light across all wavelengths, behaving as a blackbody. In contrast, isolated, low-density gases or plasmas produce distinct, discrete emission lines. Furthermore, and most importantly, it is physically impossible for the observed solar-dynamic phenomena such as sunspots, solar prominences, coronal rain, sunquakes, and solar tsunamis to occur without a liquid surface and a solid core.

Potential energy and kinetic energy are related, yet very distinct. From the widest-angle perspectives they are equals. Last centuryRichard Feynman shocked the world by talking about the great energy everywhere in a seeming vacuum. He was partially correct within his quantum mechanics perspective. This century brings a better model for the potential and kinetic energies within individual y/y spheres, and along beaded-string frequency waves.

This paper analyzes a fundamental geometric oversight in the classical interpretation of the Michelson -Morley experiment. We demonstrate that in a frame moving with velocity u , the reflection of light from a mirror follows a specific angular deviation. By introducing the formula sinu2061〖β=u/c〗 √(1-u^2/c^2 ), we prove the optical paths are asymmetrical. This geometric shift provides a new basis for understanding the "null result" of the Michelson-Morley experiment without necessitating postulate of absolute constancy of light in all frames. In other words, the Michelson-Morley experiment is a failed experiment and the physical-mathematical conclusions drawn from its "results" have no scientific basis.The question of the nature of light is directly related to the Michelson-Morley experiment. Since the aforementioned experiment can be considered a failure, the idea of the ether becomes relevant. For this reason, a new idea is proposed to solve the problem of light propagation. Light is attributed only a wave nature in the form of spherical waves, and the propagation medium is dark matter. The idea is substantiated by appropriate calculations. . The mass of a dark matter particle has also been determined, which is found to be equal to M_dm≈4.〖10〗^(-34) kg.Keywords: Light, Michelson-Morley, experiment, theory, law, ether, wave, dark matter.

The Initial Entropy Problem asks why the early universe began in an exceptionally low gravitational entropy state despite matter and radiation being at thermal equilibrium. Standard cosmology accepts Penrose's Past Hypothesis as a brute empirical fact, without a dynamical mechanism that enforces it. This paper presents a candidate Center Origin White Hole Cyclic Cosmology, built from thirteen explicit axioms, offered as an axiomatic framework, not a resolution of the problem it addresses. The model proposes that the Big Bang is the time-reversed quantum-gravity bounce of a single, monolithic universal black hole. Three axioms carry the model's real explanatory weight and are flagged plainly rather than hidden in notation: Axiom 9 stipulates an explicit exception to the Second Law of Thermodynamics at the transition; Axiom 11 stipulates repulsive anti-gravity that cannot be derived from time-reversal of the Einstein field equations and is grounded only in current untestability; Axiom 13 stipulates that dark energy is dynamical rather than a true cosmological constant, an explicit, falsifiable bet on an open question in dark energy research that current measurements do not support under a constant &Lambda. The paper derives the model's recollapse dynamics as an exact consequence of the Friedmann equation for a dust-dominated closed universe and shows explicitly where this derivation fails to match a universe dominated by dark energy. The framework does not derive low initial entropy from more fundamental principles; it relocates the Past Hypothesis to a named, falsifiable transition.

Gravitational waves in the microhertz regime represent an unexplored window into slow dynamical processes in planetary interiors and the longu2011period tidal interactions within the Solar System. Jupiter, whose rotation period of 9.925 h is known with high precision, should generate a gravitational wave near 55.97 $mu$Hz if its mass distribution departs from perfect axial symmetry. Such a signal is far below the sensitivity of existing gravitationalu2011wave detectors and is strongly Doppleru2011shifted by the synodic Earth—Jupiter motion, making direct detection challenging.Using 20 years of barometric pressure data from DWD stations, we extract Jupiter’s gravitational wave through coherent demodulation of the phase modulations induced by Earth’s orbit and by the four Galilean moons. The recovered carrier frequency exhibits SNR $approx100$ and reveals a previously unknown longu2011term frequency drift associated with Jupiter’s deep interior. The modulation indices and phases of Io, Europa, Ganymede, and Callisto are stable across 752 independent realizations, demonstrating that Earth’s atmosphere responds coherently to microhertz gravitational forcing.The measured modulation indices exceed linearized Doppler predictions by a factor of 12.7, implying a propagation speed of $vapprox 0.08 c$ for the wave along the Jupiter—Earth path. Because this path lies entirely within the Sun’s gravitational potential, our results suggest that microhertz gravitational waves may experience dispersive propagation in strongly curved spacetime. No additional longu2011term phase modulations were detected. These findings open a new observational channel for studying gravitational phenomena in the Solar System at ultrau2011low frequencies.

Galactic rotation-curves shows in many spiral- and dwarfgalaxies deviations in movement from the expectation of baryonic matter alone. Usually these deviations are explained by supposing a domination of a "dark-matter" halo. Here, in this treatise an alternative scenario is discussed in the sense of Ockams Razor: not to speculate new things to safe the phenomena but to try an explanation of observed phenomena by very well-known contributions. Therefore a global galactic magnetic plasma-halo is able by supposing a magnetic pressure and stress-term to deliver an additional dynamical term to movement of stars. This model doesn’t substitute gravity but elaborates the eeffective dynamics by magnetohydrodynmical effects (MHD).

In this versionV2 Universe`s age goes down 14.3Gyr This work presents the first application of the Dark Matter by Quantum Gravitation (DMbQG) theory to the study of the dark matter (DM) at cosmological scales. In the section 2 are introduced the Friedmann equations using the DMbQG theory, a key feature of this approach is the explicit separation between baryonic matter density and dark matter density. It is remarkable how in the DMbQG framework is demonstrated using the second Friedmann equation and the cosmological conservation equation that the effective DM density is a half of the physical DM one. This theoretical finding has several successful consequences studied in the sections 3 and 4. Also in this section, it is calculated the transition between the decelerating- accelerating eras, according to the DMbQG theory and the ΛCDM model. The theoretical calculus are tested with other published results. In the section 3, it is calculated the current cosmologic deceleration parameter by the two theoretical frameworks, being tested this calculus with other published results. Also it is studied the cosmological deceleration function depending on the z red-shift according to the two frameworks, yielding two quite different functions that could be tested by the recent results of the DESI project. In the section 4, the Universe`s age is calculated first within the standard ΛCDM model and subsequently using the DMbQG framework. A central result is that the age integral obtained with DMbQG is approximately 12.5% larger than that derived from ΛCDM. This difference allows for consistency with the Hubble constant measured by the PANTHEON project, based on Type Ia supernovae , with Hu2080 = 73.5 km /s/ Mpc, yielding an age of 14.3 Gyr. In contrast, applying this same value within ΛCDM leads to an age of 12.8 Gyr, in tension with the oldest known astrophysical objects. Consequently, ΛCDM relies on the Planck Collaboration value, Hu2080 = 67.4 km /s/ Mpc, which gives an age of 13.85 Gyr.Given that the SHOES or PANTHEON+ projects provide a more direct measurement of the present-day expansion rate, while the Planck value is inferred from early-Universe data (cosmic microwave background), the former may better represent the current Hubble parameter. The Hubble tension remains one of the major open problems in cosmology, and this work suggests that the DMbQG framework may offer a partial resolution by reconciling a higher Hu2080 value with a consistent estimate of the Universe’s age.
