Gravitational Analogy of Casimir-Effect from Qed to Gravity Description in GRT by Extended GRT-Gravity Without Ostrogradsky Ghost-Problem as Higher Derivative of Effective Gravitative Fieldtheory. a Global Fixpoint-Solution.

Classical GRT of Einstein-description of gravity-theory can be extrapolated to higher structures. This extension adds higher-order terms to classical general relativity because GRT itself can be assumed to be a first-order expansion of spacetime. These higher corrections can lead to new observations in the vacuum, with gravitational waves, or black holes. Furthermore, an attempt is made to transfer the Casimir effect of quantum electrodynamics as an analogy from the electromagnetic vacuum to a spacetime description and to describe this analogy as a gravitational effect within GRT.

Non-inertial Relativity Theory, MOND and Generalized Gravity in Curved Phase Spaces

Authors: Carlos Castro
Comments: 22 Pages.

We pursue further our work on (Born Reciprocal) Non-inertial Relativity theory. Starting with a brief review of the theory, and how Non-inertial Relativity redefines the notion of mass, the phase space particle trajectories in $ D = 2 + 2 $ are revisited by emphasizing the key difference between a truly $U(1,1)$-invariant mass $ {cal M }$ and the Lorentz-invariant mass $m$. The derivation of the generalization of the special relativistic expression of $ E = m ( 1 - v^2 )^{ - 1/2} $ ($c=1$) to the non-inertial relativistic case follows. This, in turn, leads to the non-inertial relativistic extension of Milgrom's modified Newtonian dynamics (MOND) law. In the most general setting, one finds proper-time $ m ( tau ) $, and spacetime-dependent $ m ( x^mu)$ masses for point particles, when the proper force $ F $ depends on $ tau$ or $ x^mu$, respectively. By recurring to the tools of Finsler geometry, we finalize by writing the generalized gravitational field equations in curved phase space in the presence of matter sources, like particles and cosmic strings. As a result, both spacetime and momentum space are curved. We conclude with some remarks as to why curved momentum space should play an important role in quantum gravity.

Introduction to the Quantum Theory of Electrogravitation

Authors: Arcangelo Recchia
Comments: 110 Pages.

In the first chapter, the "conversion factors" are introduced, which are dimensionless coefficients used to evaluate the effect of accelerated expansion of spacetime on measurements. It is shown that these factors can be expressed through a common parameter, α, the fine-structure constant, which is linked to the ratio between the theoretical radius (13.6-13.8 Gly) and the measured radius (46.5-47 Gly) of the universe.

In the second chapter, it is demonstrated that dark matter and dark energy do not exist, and the gravitational effects attributed to them are actually caused solely by ordinary matter.

In the third and fourth chapters, Newton's theory of gravitation is first extended into the generalized gravitational theory and then into the generalized electrogravitational theory. The latter, among other things, predicts the existence of electrogravitational waves, suggesting that photon and graviton are the same particle and that the graviphoton is constituted by two elementary electric charges of opposite sign.

In the fifth chapter, Planck's law is derived from first principles. This implies that Planck's constant is no longer a fundamental constant but derivable from other constants.

In the sixth chapter, the electrogravitodynamic equations and the electrogravitational stress-energy tensor are developed.

In the seventh chapter, the quantization of Einstein's field equation is carried out.

In the eighth chapter, the possibility that elementary particles are in turn composed is examined and discussed: we have seen that the graviphoton corresponds to the elementary particle composed of two electric charges of opposite sign.

In the ninth chapter, the mass ratio between proton and electron (approximately 1836) is calculated.

In chapter ten, the concept of force is revised, as all particles can be exchanged, making them all carriers of force.

In chapter eleven, the multiverse with repeated gravitational collapses (like a matryoshka) is introduced.

In chapter twelve, the theory of information is integrated with the electrogravitational field: Information must be "contained" by something, whether it be a stone slab, a book, a CD, or any other means. This raises the question of whether there exists an ultimate level on which information can be encoded, the level of fundamental "0" and "1". This can only be spacetime itself (the electrogravitational field).

On a Unified Speculative Framework Connecting Cyclic Conformal Cosmology, de Sitter Holography, and Fuzzball Boundary States

We present a speculative theoretical framework that attempts to connect three distinct structures in contemporary theoretical physics: Penrose's Conformal Cyclic Cosmology (CCC), the de Sitter/CFT correspondence (DS/CFT), and the fuzzball description of black hole microstates in string theory. The central conjecture is that the asymptotic conformal boundaries of eachcosmological aeon — identified in CCC as the interface between successive aeons — may bereinterpreted as fuzzball boundary states within an eleven-dimensional M-theoretic substrate, with the intervening de Sitter geometry playing the role of a transient geometric bridge. TheEinstein-Rosen/Einstein-Podolsky-Rosen (ER=EPR) conjecture is proposed as the structureinvariant under conformal transitions, providing a mechanism for information preservation acrossaeon boundaries. We further conjecture that the apparent separation between past and futurefuzzball states is an artifact of dimensional projection from eleven to four dimensions, and that inflation may be interpretable as the geometric response to the quantum entanglement initialisation complexity of the nascent de Sitter bridge. Each component of this framework is explicitly classified by its epistemic status. No claim of mathematical derivation is made; this work is a speculative research programme identifying open questions and potential falsification directions.

Emergent Quantumcorrelations as Global Fixpoint-Structure in Topotronics-Theory.

Authors: Holger Döring
Comments: 27 Pages.

Reconstructed are the fundamental basic ideas in a minimal superdeterminism-model. The global fixpoint structure codates measurements and apparates simultaneous, while an selector-operator generates stability and coherence via a minimal-principle. Discrete functions of measuring and on reproduce exactly the quantum correlations . The CHSH- correlations appear at the emergent quantum area , whereby the Bell-unequation appears as an emergent, not as a fundamental physical law. The minimal measurable deviation is . The model offers a consistent, logical structure, connecting superdeterminism and emergent effective quantum logic. Classical quantum structure appears not on a fundamental level but only as an emergent overlaying structure like in the demand of Einstein. Particularly in the connection with a theory of quantum gravity it is necessary to explore new ways of formulating fundamental spacetime-structures like quantum states to get greater significance in the clearness of a consistent underlying description.

The Daon Theory - A Unified Framework for Fundamental Physics

Authors: J. E. S. Gustafsson
Comments: 148 Pages.

This theory is built from first principles, using Euclidean geometry and classical mechanics, and is designed to be accessible to readers with a basic understanding of physics. All constants are derived numerically, and the derived theory agrees with experimental data.
