We present Infinite Flow Cosmology (IFC), a brane-world framework in which the observable universe is modelled as an open thermodynamic system embedded within a dynamic, radiating 5D Vaidya-Anti-de Sitter bulk spacetime. Rather than invoking a static cosmological constant, IFC drives late-time cosmic acceleration through continuous mass-energy flux projected from the bulk onto the 4D brane. Using the Shiromizu-Maeda-Sasaki projection formalism, we derive the modified Friedmann equations and a generalised energy conservation law governing bulk-brane exchange. We constrain the dimensionless bulk-brane coupling constant to α ≈ 2.2 by matching the observed late-time expansion history, and derive an effective quintessence-like equation of state w(z) ≳ −1 that is distinct from and testable against a pure cosmological constant. The model predicts a mild but measurable enhancement in the large-scale structure growth parameter fσu2088 at redshifts z < 0.5, forecasting a signal detectable by the Euclid satellite and DESI survey. Finally, we demonstrate that localised bulk flux preferentially couples to regions of extreme spacetime curvature, providing a two-channel gravity-based mechanism for super-Eddington black hole accretion that simultaneously explains anomalous mass growth rates and the persistence of bright X-ray coronae and radio jets — observations that challenge standard slim disk models

The article points out several errors in the expanding space theory that is currentlybelieved to explain the cosmological redshift. The article proposes a tired light theory thatgives the correct reduction factor. This tired light theory includes a mechanism that slowsdown transitions of electrons in the atomic level. The mechanism is not explained: it is only proposed that the fine structure constant changes over long time periods. The articlesuggests that Cosmic Microwave Background radiation did not come from the Big Bang and that it comes from lost energy of photons traveling through the space as in tired light theories.

The Big Bang Theory (BBT) is currently widely accepted. The theory explains the expansion of galaxies by the action of "dark energy", a mysterious force that repels matter and causes space to expand at an accelerating rate. Within galaxies, the action of gravity prevails over the force of "dark energy" and no expansion occurs. This situation motivates the search for alternative physical interpretations based on verified observational data.A new physical interpretation of gravity is proposed to complement existing cosmological models. The theory is formulated both as a phenomenological framework and as a microscopic description explaining gravitational interaction at the atomic level. The proposed approach is constructed as a connected sequence of known physical phenomena, each of which has experimental confirmation. This provides a physically grounded basis for interpreting gravitational interaction across scales.A distinctive feature of the theory is its emphasis on the physical mechanisms underlying the formation and action of the gravitational field, while mathematical modeling is treated as a secondary descriptive tool. The theory offers a possible physical interpretation of the formation of cosmic structure driven by gravity alone. According to the proposed framework, gravitational interaction may manifest itself as either attraction or effective repulsion depending on the physical state of interacting matter. Within this interpretation, the observed expansion of the Universe may be described without invoking hypothetical forms of energy such as dark energy.

From the dawn of civilization Humans struggled to understand and explain their environment. The process of that struggle resulted in various branches of investigations and knowledge, which Humans denote as Science.Because the Human mind, which created this Science, is by itself composed of components which might be the same components that the environment is also composed of, Humans might be bound to never being able to understand and explain completely this environment, which is also denoted as the Existence, because one cannot explain an issue, if that explanation relies on this same issue. Nevertheless, Humans were still able to build a magnificent structure, of knowledge and explanations, which, as mentioned above, is denoted as Science which is still an ongoing endeavor, which continuously expands, reveals and explains more and more secrets embedded in the Existence.However, the nowadays Physics, which is the branch of Science which specifically focuses on understanding and explaining the Existence, is still composed of branches which are not fully compatible.One of these branches is the branch denoted as the Classic Physics, which focuses on understanding and explaining what is denoted as the Macroscopic Environment.Another such branch is the branch denoted as the Quantum Physics, which focuses on understanding and explaining what is denoted as the Microscopic Environment.And, as presented above, these two branches of Physics are not fully compatible, and Humans are still struggling, to expand the knowledge that might bridge the gap that still exists between these two branches of Physics.Moreover, even the branch of the Classic Physics itself, still embeds branches which are also not fully compatible, as for example, the Gravity and the Electromagnetism, and more must be done to bridge the gap that exists also between these two branches, which both belong, as stated above, to the branch of the Classic Physics.In the process of building the above-mentioned magnificent structure of Science, Humans detected in the Existence various components, and denoted these components as Entities, and used these Entities as the building blocks on which the Science of Physics was constructed.Two such Entities are the Entity of Space and the Entity of Time, which together were interweaved into one Entity, denoted as Einstein's four-dimensional Interwoven Space-Time Entity, by the Relativity Theories of Einstein.The branch of Classic Physics relates to the four-dimensional Interwoven Space-Time Entity as a real component, that really exists in the environment, or the Existence.Moreover, the branch of Classic Physics states that the environment embeds just one single four-dimensional Interwoven Space-Time Entity which is a real component of the environment, that really exists in the environment.However, this paper argues, that the branch of Quantum Physics, might also imply that the above-mentioned four-dimensional Interwoven Space-Time Entity might not be a component that really exists in the environment, or the Existence.Moreover, this paper also argues, that although the nowadays branch of Classic Physics does state that the four-dimensional Interwoven Space-Time Entity is a real existing Entity, a contrary conclusion can be also derived, a conclusion that the four-dimensional Interwoven Space-Time Entity might not be a component that really exists in the environment, or the Existence, and that contrary conclusion can be also derived from arguments based only on the nowadays Classic Physics.Thus, if it can be concluded that arguments based only on the Classic Physics might imply that the four-dimensional Interwoven Space-Time Entity does not really exists in the Existence, a conclusion which might be also in line, and compatible, with what the Quantum Physics also implies, then, by abandoning the conclusion that the four-dimensional Interwoven Space-Time Entity is a component that really exists in the environment, and by validating the assumption that the four-dimensional Interwoven Space-Time Entity might be only a facet or an attribute of another component of the Existence, which the Science of Physics denotes as Energy, this might provide also a lead for starting some bridging between the Classic Physics and the Quantum Physics, which, as already stated above, are still significantly incompatible.

We propose an experiment to test whether the one-way speed of light is isotropic, without relying on clock synchronisation between separated stations. Two identical stations separated by a fixed distance exchange laser beams through complementary shutters driven by independent atomic clocks. The phase relationship between the two stations' light maxima directly encodes any asymmetry in one-way light speed. No synchronisation signal is required and the measurement is not circular. Relative clock drift between stations is monitored by observing whether the inter-station timestamp offset remains constant over the measurement interval. This offset is not interpreted as a one-way propagation time and does not constitute a synchronisation convention -- it serves solely as a stability diagnostic. The known frequency precision of atomic clocks, combined with regular monitoring of this offset, provides sufficient warranty of system integrity. The experiment is sensitive to any preferred-frame velocity component along the baseline. The true velocity of the apparatus through such a frame -- if one exists -- is unknown. Earth's orbital velocity of approximately 30 km/s is a lower bound only; contributions from the motion of the solar system and galaxy relative to other astronomical reference points could raise the true figure substantially. A null result would constrain preferred-frame theories. A non-null result would warrant careful independent replication.

Following the analogy with the Feynman electromagnetic retardation potential formula,it is necessary to derive the energy conservation equation, which requires the concept of "repulsion." The four equilibrium forces governing Mercury's orbit consist of gravity, mass fieldforce, centripetal force, and another force; integrating this formula yields the energyconservation equation.

In relativity theory the advance of an atomic clock in a GPS satellite of some38 microseconds in 24 hours is explained by time dilation because of velocity from the Special Relativity Theory and time dilation in a gravitational field from the General Relativity Theory. The article shows that the time advance of a GPS satellite can be explained without any relativity theory and the formulas are in the first order the same as inthe relativity theory. It is also shown that the calculation of the GPS clock advance from the relativity theory is incorrectly made: in relativity theory there is the equivalence principle and because of it, the time dilation caused by acceleration due to the curved orbitmust be included. When it is included, the clock advance is incorrect. It is also shown thatEinstein's 1907 calculation of the gravitational redshift is incorrectly made, though theresult is correct.

Based on numerous physical experiments that can easily be performed by anyone, the arrangement of different matter of varying densities which are contained in a vessel are always arranged in a particular order when a force is applied to that vessel and that vessel is put into motion. The direction of the motion dictates the density gradient orientation. Based on other experiments it is also apparent that this arrangement of matter (based on density and dependent on the direction of motion) ceases when objects are in free fall. This would imply that when objects are in free fall there is no force present that is responsible for the apparent downward motion of objects, but rather the reference frame (earth) is moving upwards to meet the objects. This concept is explored (the upwards motion of the earth) and calculations are performed to understand how we (standing on earth) can perceive a downward acceleration (g) of objects in free fall if the earth is in motion upwards. Other concepts regarding the motion of the earth are also discussed.

We will show that, within the "Decreasing Universe Theory" (DUT), time inside a gravitational field isaltered in the same way as spatial distance measurement scales. At the cosmic level (timescales of millions of years), this effect becomes perceptible and explains the variation in the measured duration of Type Ia Supernova (SN1A) explosions.

A recent work explores the Riemannian geometry of Victoria-Nash Asymmetric Equilibrium (VNAE) manifolds. A fourthu2011order cancellation in the curvature tensor follows from Schwarz's theorem and Riemann antisymmetry. This resolves the higheru2011order complexity that hindered Einstein's nonu2011symmetric field theory. The same mechanism suggests a conceptual parallel with the Navieru2011Stokes regularity problem, though no solution is claimed.

The object formally designated C/2025 N1 (ATLAS) has been widely discussed as a candidate third interstellar object ("3I/ATLAS") due to its strongly hyperbolic trajectory. In standard celestial mechanics, an interstellar origin is inferred when the original barycentric eccentricity significantly exceeds unity prior to planetary perturbations. This interpretation, however, implicitly assumes that cometary dynamics are governed solely by gravitational forces and conventional outgassing.In this work, we propose an alternative hypothesis: C/2025 N1 (ATLAS) is not interstellar but a Solar System small body originating from the Oort Cloud, consistent with the framework of World—Universe Cosmology (WUC). We argue that its large excess velocity can be explained by a non-gravitational internal acceleration mechanism involving partial conversion of rotational energy of the nucleus into translational kinetic energy.Within WUC, the Universe is structured as a hierarchy of interaction regimes—Macro-world (gravity), Large-world (extremely-weak interaction), Small-world (super-weak interaction), and Micro-world (weak interaction). Previous studies associate Ball Lightning [1] with Solar System Small Body (SB1) and interpret the Tunguska superbolide [2] as an SB2 analogue. Extending this hierarchy, we identify C/2025 N1 (ATLAS) as an SB3 object. This model naturally accounts for its extreme hyperbolic excess velocity without invoking an interstellar origin and leads to specific, testable predictions regarding kinematics, activity, and radiation signatures.We compare these predictions with observations of ʻOumuamua, C/2019 Q4 (Borisov), and a growing population of low-albedo asteroids and "dark comets" exhibiting dust-poor outgassing.

We propose a cosmological framework in which the observable matter content arises from a measure-theoretic structure rather than additional particle species. The construction distinguishes between a metric (Lebesgue-type) measure and an invariant structural (Haar-type) measure. Their interplay leads to a finite dark-matter distribution, a visible matter component localized near a crossover scale, and a predicted abundance ratio $Omega_{m DM}/Omega_b approx 5.4$ without introducing new particles.

It is proposed to increase the number of positive and negative Λ-terms in Einstein's vacuum equation to infinity. The solution to this equation leads to a closed Universe filled with a virtually infinite number of "corpuscles" (i.e., stable convex spherical vacuum formations) and "anticorpuscles" (i.e., stable concave spherical vacuum formations) with a hierarchical discrete set of radii. These "corpuscles" and "anticorpuscles" of different scales are nested within one another like Russian dolls. Thus, they form a multitude of hierarchical chains, all beginning with the core of a single largest "corpuscle" (i.e., the mega-Universe) and culminating in a single core of the smallest "corpuscle" (i.e., the instanton). As a result, a closed Hierarchical Cosmological Model was obtained, which allows us to outline the ways of solving many problems of modern physics, such as: baryon asymmetry of the Universe, confinement of quarks, geometrization of electric charge, gravity, dark matter and energy, etc. This article is a development and refinement of the Geometrized Vacuum Physics Based on the Algebra of Signature (GVPh&AS), presented in the articles [3,4,5,6,7,8,9, 10,11,12,13,14,15,16].

We present a model of a purely geometric source of Dark Energy (effective cosmological constant) within the framework of Hyperhamiltonian Quantum Mechanics where spacetime acquires a locally compact Lie group structure with two volume measures (Haar, generated by the multiplication on the group, and Lebesgue, induced by the natural closed FLRW metric of the group). Following earlier suggestion by one of the authors that the group-invariant Haar measure may address non-Newtonian behavior at large scales, it is taken to represent vacuum energy density, while Lebesgue is assumed responsible for matter/radiation density. It is shown that Haar vacuum energy mimics dark energy at cosmological scales, generating accelerated expansion geometrically without an explicit cosmological constant. We develop a self-contained linear cosmological perturbation theory to show almost perfect agreement with LambdaCDM.

It is self-evident that no knowledge of or surroundings can exist without observations from us or our fellows. This knowledge can of course be transferred to others, changing the context in which we perceive and understand our universe. I use the idea that both velocity and gravity can be described as a "potential for observation", for a lack of better vocabulary. With the function f(x)=(1/x) and the inverse of the derivative of the Lorentz transformation, both Einsteinian kinetic energy and relativistic gravity can be computed. With the constants c and G, it is possible to construct a version of postnewtonian relativistic gravity, consistent with basic parts of Einstein's theory, but also suggesting a calculation of the expanding universe, deduction of an exact value of the Hubble constant, with no other constants involved than c and G.
