Principal Limitation of Metric Measurements in Real Radial Gravity Fields

Authors: Holger Döring
Comments: 4 Pages.

Since there are no real inertial systems in reality, when a weak gravity field appear, because only radial gravity fields exist and no homogenous fields, there only a quasi inertial system (QUIS) can be constructed in these fields. Real inertial systems are only constructable in fieldfree spaces, far from every material body and neglecting quantum gravity structures. If gravity fields appear, even weak ones like in example of Earth field, only QUIS are constructable. This QUIS allows only a limited description of physical measurements because it deals with radial field lines of gravity, which are supposed to have a range of Planck-length at the center of Earth resp, the material body. Then the smallest QUIS, which can be constructed on the surface of planet Earth has a range of ca. 10u207b¹u2075 m. Smaller metrical length statements on the surface of Earth are senseless. If the measurements have to be finer, one must go afar from surface of the planet, where the radial field lines have greater distance and in this case greater QUIS can be defined. Then physical behaviour of interactions then can be described without contradictions in smaller ranges.

Possibility of Spacetime Dimensions as Orthogonal Quantum States

Authors: Holger Döring
Comments: 12 Pages.

There is the possibility that on a Planck-scale the universe is not a fourdimensional manifold but only a flat spacetime, consisting only of a permanent timelike dimension and periodic caused spacelike dimensions by the quantum potential of this timelike dimension. In this case the quantum-states of spacelike dimensions form an orthogonal system. For this model a twodimensional Riccitensor can be constructed for every dimension and four of them can be formed to a fourdimensional structure but without intercoupling. A possible intercoupling then would lead to description of classical GRT-structure. This model also can be described mathematically by a special hypocycloide, a deltoide, where the points of the curve mapping exactly on the outer circle of the rotation process. These are the resonance-points of the timelike with the spacelike potentials, causing the dimensions as triple eigenvalue of signature. And so a form of ON/OFF-operators are introduced, which shows similiar structures as spin-operators and can possibly be used to describe the forming of the dimensions.

The Evolution of the Universe from the Big Bang to the Big Bounce

Authors: Yvan-Claude Raverdy
Comments: 7 Pages. (Note by ai.viXra.org Admin: Please use sytandard/smaller font size, e.g., Time New Roman 12 pts)

The hypothesis of a Superfluid Space-Time (granular quantum) is consistent with knowledge acquired in Cosmology and, moreover, conform to the Standard Model. We show, here, that the relationships arising from this hypothesis can also allow to go further in predicting the numbered evolution of the Universe. They lead to the accreditation of a cyclical evolution incorporating a rebound (Big Bounce), identical to the Big Bang, through an explosive phase transition.

A Topos-Theoretic Formulation of General Relativity: Emergent Spacetime from Sheaf-Categorical Principles

Authors: Yuanjian Li
Comments: 7 Pages. (Note by viXra Admin: Please submit article written with AI assistance to ai.viXra.org)

We present a comprehensive reformulation of General Relativity using category theory, sheaf theory, and topos theory, providing an alternative to the traditional differential geometric framework. The fundamental construct is a category Loc of local spacetime regions equipped with a Grothendieck topology, forming a site (Loc, J). Physical observables are represented as sheaves on this site: the metric sheaf Met, matter sheaf Mat, and their derived structures. The EinsteinField Equations emerge not as differential equations but as natural transformations between functors, defining the solution sheaf Sol—the subsheaf of local configurations satisfying the equations of motion. We develop internal differential geometry within the topos Sh(Loc, J), constructing the Hilbert action as a natural transformation and deriving the field equations from an internal variational principle. A model of General Relativity corresponds to a global section of Sol. This formulation provides a robust mathematical foundation for quantum gravity research and offers natural pathways for unification with quantum theory within a common topos-theoretic framework, while maintaining complete consistency with established experimental results.

Quantum-Gravitational Machine Learning: A Theoretical Model for High-Energy Social Intelligence

Authors: Debabrata Chini, Deblina Biswas
Comments: 15 Pages. (Note by viXra Admin: Please submit article written with AI assistance to ai.viXra.org)

This paper introduces a purely theoretical framework that fuses quantum information theory, general relativity and machine learning to construct a high-energy intelligence model with direct application to large-scale social systems. By leveraging entangled quantum networks in curved spacetime and high-energy field dynamics, the proposed model formulatesa new kind of non-classical learning system with relevance to urban optimization, predictive disaster modeling, and secure communication infrastructure. Using rigorous field-theoreticcalculations, we show how curvature, energy, and quantum state compression can drive intelligent data flow under extreme physical and informational constraints. All derivations, graphs and architecture designs are grounded in first-principles physics, with no experimental data involved. This work offers a new path for theoretical AI systems that are not limited by classical assumptions, proposing a future direction for socially embedded computation based on fundamental physical laws.
