The equivalence principle, uniformly accelerated reference frames, and the uniform gravitational field

TL;DR

This paper clarifies the relationship between uniformly accelerated frames and uniform gravitational fields in relativity, demonstrating that the equivalence principle holds without restrictions or approximations.

Contribution

It refutes previous claims by showing the equivalence principle remains valid in relativistic contexts without restrictions.

Findings

Equivalence principle holds in relativistic uniformly accelerated frames.

No need for Newtonian or small enclosure approximations.

Previous assertions of breakdown are incorrect.

Abstract

The relationship between uniformly accelerated reference frames in flat spacetime and the uniform gravitational field is examined in a relativistic context. It is shown that, contrary to previous statements in the pages of this journal, equivalence does not break down in this context. No restrictions to Newtonian approximations or small enclosures are necessary.
