The recent discoveries of distant galaxies with a redshift z > 10 seem to call into question the estimate of 13.8 billion years for the age of the universe. The age of some of these galaxies is estimated to be close to or even greater than the age of the universe, a result that seems impossible to make compatible with the estimated age of the universe in the Standard Model. Therefore, the scientific community is studying the possibility of modifying the current value of this age and is reviewing the procedures that led to its current estimate. We therefore ask ourselves whether, with a universe age of 13.8 billion years, we can measure intergalactic distances greater than 13.8 billion light-years. The answer we arrive at in this work is that, theoretically, it is possible to measure significantly greater intergalactic distances in our current universe without needing to modify the age of the universe. We have reached this conclusion by studying the consequences that the spatial curvature of our universe has on the estimation of these distances. First, we determined the sign of the spatial curvature of the universe at present. We then developed a cosmology consistent with that sign, and finally, we determined distances and times. The conclusion is that it is possible in our current universe to measure distances significantly greater than its age in light-years allows, making current experimental results compatible with the value of the age of the universe.

We present a novel cyclic cosmological framework that resolves fundamental issues in standard cosmology through the integration of conformal geometry, quantum gravity effects, and holographic principles. The Phantom-Quantum Bounce (PQB) Cycle model incorporates: 1) A dynamically evolving phantom field with multi-component potential that drives cyclic expansion-contraction phases, 2) Loop Quantum Gravity corrections that eliminate the initial singularity through a well-defined quantum bounce, and 3) An entropy reset mechanism via ER=EPR-based disentanglement of soft hair degrees of freedom at the conformal boundary. The model makes three distinctive predictions testable with near-future observations: a CMB temperature correlation function exhibiting double-ring anisotropies, a dark energy equation-of-state parameter w0 = -1.2 ± 0.05, and anomalous redshift drift at z ~ 4 that exceeds ΛCDM predictions by an order of magnitude. Numerical verification confirms the model's mathematical consistency despite its unconventional development pathway.

Comments: 11 Pages. Updated Version (v2) with full 175-galaxy analysis and formal mechanical expansion derivation. Includes an independent AI technical audit (Validation ID: QST-EVO-2026-VM-v2-AUDIT). Complete data products and graphical atlas available at: https://github.co
We present a systematic morphological analysis of 175 galactic rotation curves from the SPARC database. We introduce a unified geometric metric, the Alpha Angle (α), to quantify dynamical maturity. Results reveal a strong correlation (R=0.89) between α and sSFR, yet identify anomalies (NGC 2841, F574-2) that challenge SFR as an absolute clock. We propose a mechanical model where galaxies undergo secular expansion due to mass loss ($dot{r}/r = -dot{M}/M$). The derived local expansion rate matches the Hubble constant ($H_0$), suggesting cosmic expansion as an emergent property of local mechanical relaxation. This version includes an independent AI technical audit (ASAS Report

This paper introduces the Dual Universe Hypothesis, a cosmological model in which stars and black holes form a fundamental feedback system responsible for the creation and recycling of matter, energy, and information across cosmic time. In contrast to the linear entropy-driven model of mainstream cosmology, this work posits that the universe operates through recursion, with stars acting as engines of matter creation and black holes as agents of compression, transformation, and ejection.The theory integrates elements of General Relativity, Quantum Mechanics, and a novel formulation of Pressure-Driven Gravity (PDG), which reframes gravitation as a result of vacuum pressure gradients in a compressible spacetime medium. In addition, the Mirror Thesis is introduced as a speculative but cohesive metaphysical framework proposing that the universe evolves through reflection, feedback, and informational symmetry.Mathematical formulations include modified Einstein field equations with vacuum pressure terms, vacuum-based Euler equations for gravitational acceleration, and recursive operators for cosmic information encoding. The black hole information paradox, vacuum energy, entropy, and the arrow of time are all reexamined through this lens.This work is intended as both a theoretical model and a philosophical synthesis, offering an original approach to unifying physics and cosmology beyond standard paradigms.

Most physics theses point toward some sort of destination, or physics model, that will be tested by their experimental data. Stringy field models are more 2D maths than real physics, so they can best be described as untestable algebras that ignore much of 4D physics. Astrophysics today fails to fuse 2D field maths with sketchy ideas of virtual quantum particle fields. Science needs an elegant direction of inquiry embracing physically verifiable 4D destinations to the degree possible.

Calculating the distance of a star from Earth using stellar parallax makes sense only in two cases. In the first case, this is possible if the object we are observing is stationary in relation to the Sun and in the second case if the measurements are made simultaneously, but from two different locations. We will consider the case when the star moves uniformly with respect to the Sun. By measuring the Doppler effect at three different points, we will be able to determine the speed of light emitted from the star in the direction of the observer, the velocities at which the star and Sun move regarding the referential coordinate system and finally we will calculate the distance between the star and the observer.

This work proposes a cosmological model in which our universe is conceptualized as a threedimensional "bubble" formed within a higher-dimensional, quantum fluid-like primordial ocean medium. Integrating modern cosmological frameworks such as cosmic inflation, the holographic principle, brane cosmology, and fluid-gravity analogies, the model proposes that the universe emerged as a local explosion within a larger physical structure. The formation of the bubble could have been initiated by an external trigger related to the negative pressure of the medium surrounding the bubble, or by a phase transition or internal local explosion, explaining the observed accelerated expansion of the universe. The external medium could be the source of dark energy. The boundary of the bubble is treated as a reflective, informationencoding interface that interacts with electromagnetic and gravitational waves, potentially leaving observable cosmological signatures. The assumption that the ocean surrounding the bubble obeys different physical laws exhibits behavior consistent with scenarios in quantum gravity and multiverse theories. Testable predictions could include spectral distortions in the Cosmic Microwave Background (CMB), echoes in gravitational wave data, and topological patterns in the distributions of large-scale structures. This model brings together existing paradigms in cosmology while providing new insight into the nature, boundaries, and origin of our universe.

We present a fit of the rotation curve of galaxy UGC 1281 using a model based on metric inflow velocities, without invoking dark matter. The model relies on a minimal set of physical parameters: bulge radius (R), baryonic bulge mass (M), and the cosmological Hubble parameter (H(z)). We evaluate the performance of the model using two fixed values for (H(z)) based on the Planck and SH0ES determinations of (H_0). The ability of the model to differentiate between these cosmological values is discussed.

In the Standard Model of gaseous stars, temperature plays an indispensable role in generating the gas pressure which prevents ‘gravitational collapse’. Yet, as stars age in this model, changes in thermonuclear fuel lead to decreased temperatures and associated internal pressures. Gravitational forces between gas particles begin to dominate and stellar collapse results. The process results in ultra-dense compact objects including white dwarfs, neutron stars, and black holes. The Chandrasekhar limit plays a central role in the theory of white dwarfs by constraining dwarf mass. These transformations have been described using thermodynamic expressions. Yet, within any given thermodynamic relation, not only must units balance on each side, but so too must thermodynamic character. Whether or not equilibrium conditions are established, temperature must always be intensive in macroscopic thermodynamics and mass must always be extensive. The theory of temperatures and pressures within gaseous stars is constructed from the kinetic theory of an ideal gas, by which temperature is introduced, in combination with gravitational and Coulomb forces. The resulting thermodynamic relations impart non-intensive character to temperature, non-extensive character to mass, and thermodynamically unbalanced luminosity relations. Consequently, the theory of gravitational collapse of gaseous stars to form compact stellar objects is not valid. Stars cannot be gaseous in nature. Rather, they must be comprised of condensed matter, most likely metallic hydrogen, and therefore essentially incompressible.

A new ontological model of the Universe is proposed, in which all observed reality is an illusiongenerated by the interaction of two fundamental entities: infinite energy strings and stable nodes on them. Gravity is explained as a mathematical difference in the rates of diameter expansion of strings in different regions of the network. The constancy of the speed of light, time dilation, inertia,cosmological redshift, black hole event horizon, redshift flickering in accretion disks, the absence of the Big Bang, black hole evaporation, the emergence of life and consciousness are consequences of a single dynamic: string diameter growth, cyclic oscillations, angular dependence of interaction, and selection for pattern stability. The model introduces no additional entities and explains observedfacts within a single simple structure.

This paper proposes that entanglement driven forces act as a fundamental component of cosmic structure stability. Conventional physics assumes forces propagate at finite speeds but we will assume otherwise. We postulate that entangled objects share a unified quantum state that allows instant interaction beyond classical constraints. This mechanism may account for anomalies in galactic rotation and explain synchronization of cosmic structures. A series of observational tests are outlined to verify this by offering alternative explanations for missing mass phenomenon and synchronization in galaxy motion.

The DESI collaboration has found that the acceleration of the universe’s expansion weakens with time, and JWST has found a large population of galaxies with z > 10. The Friedmann coordinates of the Robertson-Walker metric imply a Big Bang birth of the universe with unbounded expansion speed and perpetual gravitational deceleration of that expansion. The 1998 discovery that the universe’s expansion instead accelerates led to trying a cosmological constant in the Einstein equation, but this doesn’t accommodate the acceleration’s weakening with time found by DESI. Also, the large population of galaxies with z > 10 doesn’t jibe with the universe’s unbounded initial expansion speed. Einstein’s observationally-tested 1915 coordinate condition, however, is Lorentz covariant, which bounds all speeds by c. It also implies refractive gravitational slowing of incoming light, so outgoing light is accelerated. Outgoing galaxies whose z > 0.94 are similarly accelerated, so the universe’s expansion is accelerated, a gravitational effect that inherently weakens as the universe expands. We illustrate the above effects by plotting the time evolution of the simplest expanding-dust-sphere model universe in both Friedmann and Einstein coordinates.

This Paper sets out to measure the dimensionless gravitational compactness: lambda = frac{G,M_{m bar}}{R_{m eff},c^2}for 175 disk galaxies in the SPARC sample, using infrared—derived baryonic masses and 3.6 μm effective radii. This explorations lead to a surprise, and discovered: These λ values cluster very tightly around a median of 2.45times10^{-8}, roughly log-normal in shape and more than two orders of magnitude below the scale at which many modified-gravity ideas predict observable effects.Next , we asked the question whether a simple global tweak like: V_{m model}^2 = V_{m bary}^2Bigl(1 + kappa,lambda^betaBigr) could reproduce galaxy rotation curves ? Fitting kappa and beta to 3,387 data points gives an RMSE of 40.8 km/s, only a small improvement over the purely Newtonian result (43.3 km/s) and well behind MOND (∼13 km/s) or NFW dark-matter fits (∼25 km/s). Worse still, the best fit requires kappaapprox1.8times10^4, a coupling strength that feels implausibly large; an indication that this global prescription simply misses essential physics.Although this is a null result for λ-only modifications, it still yields something valuable: a new empirical benchmark at lambdasim10^{-8}. We hope that future theories - whether they invoke local accelerations, environmental dependencies, or entirely different mechanisms; will honor this scale when tackling the stubborn puzzle of flat galaxy rotation curves.
