Electrical charges in gravitational fields, and Einstein's equivalence principle

TL;DR

This paper examines the apparent contradiction between Larmor's radiation formula and Einstein's equivalence principle, providing indirect experimental evidence supporting the equivalence principle and suggesting a need to revise traditional interpretations of electromagnetic radiation in gravitational fields.

Contribution

It offers an analysis that reconciles Larmor's formula with Einstein's equivalence principle, supported by indirect experimental evidence, and proposes amendments to the traditional understanding of radiation in gravitational contexts.

Findings

Experimental evidence supports the equivalence principle.

Traditional interpretation of Larmor's formula may need revision.

Charges in free fall do not radiate as previously thought.

Abstract

According to Larmor's formula, accelerated electric charges radiate electromagnetic waves. Hence charges should radiate, if they are in free fall in gravitational fields, and they should not radiate if they are supported at rest in gravitational fields. But according to Einstein's equivalence principle, charges in free fall should not radiate, while charges supported at rest in gravitational fields should radiate. In this article we point out indirect experimental evidence, indicating that the equivalence principle is correct, while the traditional interpretation of Larmor's formula must be amended.
