A test of special relativity with stored lithium ions [PDF]

open access: greenApplied Physics B Lasers and Optics, 1994
Laser spectroscopy at the heavy ion storage ring TSR in Heidelberg allows for precision experiments testing the limits of the special theory of relativity. With an opticalΛ-type three-level system of7Li+ the Doppler shift has been measured by saturation spectroscopy as a test of the time dilatation factor γ = (1 −β2)−1/2 at an ion velocity ofυ = 6.4% c.

The Simplicity of Disproving the Theory of Special Relativity

open access: yesScience & Philosophy, 2022
Einstein’s theory of Special relativity is founded on an error made by Hendrick Lorentz.  It is not necessary to expose the mathematical inconsistencies of special relativity, since the theory collapses by simply exposing the error made by Lorentz.

Experiment for testing special relativity theory [PDF]

open access: yesPhysics of Atomic Nuclei, 2009
An experiment aimed at testing special relativity via a comparison of the velocity of a non matter particle (annihilation photon) with the velocity of the matter particle (Compton electron) produced by the second annihilation photon from the decay Na-22(beta^+)Ne-22 is proposed.

Lorentz Symmetry Violation of Cosmic Photons

open access: yesUniverse, 2022
As a basic symmetry of space-time, Lorentz symmetry has played important roles in various fields of physics, and it is a glamorous question whether Lorentz symmetry breaks.

Sine-Gordon Equation in (1+2) and (1+3) dimensions: Existence and Classification of Traveling-Wave Solutions. [PDF]

open access: yesPLoS ONE, 2015
The (1+1)-dimensional Sine-Gordon equation passes integrability tests commonly applied to nonlinear evolution equations. Its kink solutions (one-dimensional fronts) are obtained by a Hirota algorithm.

Theory of Gravity Dependent on Entropy

open access: yesReports 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]

open access: yes, 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]

open access: yes, 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]

open access: yes, 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

open access: yesRatio Mathematica
In this paper, we recall Dirac’s negative energy antiparticles, their compati- bility with particle-antiparticle annihilation into light and their lack of com- patibility with special relativity as well as causality laws.
