Comment on 'Frozen time in hyperbolic spacetime motion'

TL;DR

This paper critiques a previous work on hyperbolic spacetime motion, clarifying that the earlier conclusion about frozen time in a spaceship was based on a misinterpretation of variables and a false statement about acceleration.

Contribution

It corrects a prior claim by identifying errors in the interpretation of variables and the misconception about hyperbolic motion and acceleration.

Findings

The previous conclusion about frozen time was incorrect.

The error was due to misinterpreting distance and time variables.

Hyperbolic motion can involve changing acceleration, contrary to prior claims.

Abstract

We show that the conclusion in version 3 of the paper 'Frozen time in hyperbolic spacetime motion' that time does not move in a spaceship undergoing hyperbolic motion is wrong because of a trivial error in interpreting the distance and time variables used in the paper, and because it now incorrectly states that "Hyperbolic motion does not imply constant acceleration."
