Light Speed Invariance is a Remarkable Illusion

TL;DR

This paper challenges the postulate of light speed invariance in special relativity by demonstrating a measurable variation in one-way light speed, supporting the existence of a preferred reference frame.

Contribution

It reveals that the invariance of light speed is an illusion and provides experimental evidence for a preferred frame in an absolute space framework.

Findings

Measurable variation in one-way light speed

Illusion of invariance in two-way light speed measurements

Supports existence of a preferred reference frame

Abstract

Though many experiments appear to have confirmed the light speed invariance postulate of special relativity theory, this postulate is actually unverified. This paper resolves this issue by first showing the manner in which an illusion of light speed invariance occurs in two-way light speed measurement in the framework of a semi-classical absolute space theory. It then demonstrates a measurable variation of the one-way speed of light, which directly invalidates the invariance postulate and confirms the existence of the preferred reference frame of the absolute space theory.
