Phase tuning in Michelson-Morley experiments performed in vacuum, assuming length contraction

TL;DR

This paper demonstrates that assuming a fundamental aether frame and length contraction in vacuum Michelson-Morley experiments results in in-phase light signals regardless of orientation, supporting the existence of a non-entrained aether.

Contribution

It provides a theoretical explanation for Michelson-Morley results in vacuum by incorporating length contraction and a non-entrained aether model.

Findings

Light signals arrive in phase regardless of orientation.

Supports the existence of a non-entrained aether.

Validates length contraction as consistent with vacuum experiments.

Abstract

In agreement with Michelson-Morley experiments performed in vacuum, we show that, assuming the existence of a fundamental aether frame and of a length contraction affecting the material bodies in the direction of the Earth absolute velocity, the light signals, travelling along the arms of the interferometer arrive in phase whatever their orientation, a result which responds to an objection opposed to the non-entrained aether theory. This result constitutes a strong argument in support of length contraction and of the existence of a model of aether non-entrained by the motion of celestial bodies.
