The Myth of the Twin Paradox

TL;DR

This paper argues that the twin paradox is a misconception caused by faulty assumptions, emphasizing that Lorentz invariance holds universally and has significant implications for understanding space-time.

Contribution

It demonstrates that the twin paradox is a result of incorrect assumptions and clarifies the global applicability of Lorentz invariance in relativity.

Findings

The twin paradox does not exist when assumptions are corrected.

Lorentz invariance applies on cosmic scales, not just locally.

Faulty assumptions lead to perceived time discrepancies.

Abstract

One of the most discussed peculiarities of Einstein's theory of relativity is the twin paradox, the fact that the time between two events in space-time appears to depend on the path between these events. We show that this time discrepancy results only from faulty assumptions in the transition from one reference system to another. The twin paradox does not exist. But the Lorentz invariance of the theory has strong consequences, if we assume that it is valid not only locally, but also on cosmic scale.
