Searching for a highly unlikely frame dependent speed of light using a one-way test

TL;DR

This paper investigates the potential for a one-way experiment to detect a highly unlikely, frame-dependent variation in the speed of light, challenging the assumption of its isotropy central to Special Relativity.

Contribution

It introduces a novel approach to testing the isotropy of the one-way speed of light using recent experimental methods, addressing longstanding debates on clock synchronization.

Findings

Debates on clock synchronization are insignificant in one-way tests

Proposes a method to detect frame-dependent variations in light speed

Challenges the assumption of isotropic light speed in SR

Abstract

At first blush, what appears to be a purely physical question to measure any velocity: how to measure the velocity on a one-way trip? However, due to the debates of the clock-synchronization and the successes of Special Relativity (SR), searching of the possibility of one-way speed of light measurement did not receive wider attention since the declaration of the constancy of the speed of light in vacuum by Maxwell's Electrodynamics in 1864. However, our analysis suggests that the debates of the clock synchronization are insignificant when one uses a one-way experiment to test the isotropy of the speed of light - the fundamental postulate of SR. Searching of the possibility of one-way speed of light to test SR is introduced by reviewing recent one-way tests.
