Theory of Gravity Dependent on Entropy

Reports in Advances of Physical Sciences, 2023
Gravitational redshift decreases the resolution of measurements, causing entropy by increasing the possible microstates of position and momentum for objects within a gravitational field.

Spatial Directions, Anisotropy and Special Relativity [PDF]

, 2011
The concept of an objective spatial direction in special relativity is investigated and theories assuming light-speed isotropy while accepting the existence of a privileged spatial direction are classified.

Probing The Structure of Space-Time with Cosmic Rays [PDF]

, 2000
The study of the interactions of Cosmic Rays (CR's) with universal diffuse background radiation can provide very stringent tests of the validity of Special Relativity.

A note on light velocity anisotropy [PDF]

, 1998
It is proved that in experiments on or near the Earth, no anisotropy in the one-way velocity of light may be detected. The very accurate experiments which have been performed to detect such an effect are to be considered significant tests of both special

Problematic aspects of 20-th century antiparticles and their apparent resolution via isodual mathematics

Ratio Mathematica
In this paper, we recall Dirac’s negative energy antiparticles, their compatibility with particle-antiparticle annihilation into light, and their lack of compatibility with special relativity as well as causality laws.

The light speed versus the observer: the Kennedy–Thorndike test from GRAAL-ESRF

European Physical Journal C: Particles and Fields, 2018
High precision tests of the light speed constancy for all observers as a empirical basis of Special Relativity have continuously been among the goals of advanced experimental studies.

Physics Opportunities Above the Greisen-Zatsepin-Kuzmin Cutoff: Lorentz Symmetry Violation at the Planck Scale [PDF]

, 1997
Special relativity has been tested at low energy with great accuracy, but these results cannot be extrapolated to very high-energy phenomena: this new domain of physics may actually provide the key to the, yet unsettled, question of the ether and the ...

OPTIS - a satellite-based test of Special and General Relativity [PDF]

, 2001
A new satellite based test of Special and General Relativity is proposed. For the Michelson-Morley experiment we expect an improvement of at least three orders of magnitude, and for the Kennedy-Thorndike experiment an improvement of more than one order ...

General relativity: An erfc metric

Results in Physics, 2018
This paper proposes an erfc potential to incorporate in a symmetric metric. One key feature of this model is that it relies on the existence of an intrinsic physical constant σ, a star-specific proper length that scales all its surroundings.

General Very Special Relativity is Finsler Geometry [PDF]

, 2007
We ask whether Cohen and Glashow's Very Special Relativity model for Lorentz violation might be modified, perhaps by quantum corrections, possibly producing a curved spacetime with a cosmological constant.
