On the concept of simultaneity in relativity

TL;DR

This paper critiques a claim that an experiment disproves special relativity, arguing that the claim is based on circular reasoning and misunderstanding of simultaneity.

Contribution

It clarifies the logical fallacy in the argument claiming that simultaneity is absolute, reaffirming the conceptual consistency of relativity.

Findings

The claim about disproving relativity is based on circular reasoning.

Simultaneity remains a relative concept in special relativity.

The original argument is a logical fallacy.

Abstract

In this comment, we demonstrate that the claim by Spavieri et al., asserting that Wang et al.'s interferometric experiment disproves the special theory of relativity by revealing that simultaneity must be an absolute concept independent of the observer's state of motion, is based on circular reasoning and therefore constitutes a logical fallacy.
