Ether and Relativity

TL;DR

This paper discusses the historical debate between ether theories and relativity, reviews recent observational challenges to relativity, and explores modified models addressing these phenomena, aiming to enhance understanding and broaden perspectives.

Contribution

It offers a comprehensive review of ether and relativity debates, recent observational challenges, and the potential for unified modified models to explain these phenomena.

Findings

Webb redshift observations challenge standard relativity

Ultra high-energy cosmic rays suggest modifications to relativity

Multiple models proposed without a unified mechanism

Abstract

We consider one of the fundamental debates in performing the relativity theory, namely, the ether and the relativity points of view, in a way to aid the learning of the subjects. In addition, we present our views and prospects while describing the issues that being accessible to many physicists and allowing broader views. Also, we very briefly review the two almost recent observations of the Webb redshift and the ultra high-energy cosmic rays, and the modified relativity models that have been presented to justify them, wherein we express that these justifications have not been performed via a single model with a single mechanism.
