Redshift for massive particles

TL;DR

This paper demonstrates that massive particles experience a redshift in an FRW universe similar to photons, with the effect depending on their mass, derived from classical mechanics principles.

Contribution

It reveals a novel redshift effect for massive particles in FRW metrics, extending classical mechanics insights to cosmological particle behavior.

Findings

Massive particles exhibit a redshift analogous to photons.

The redshift depends explicitly on particle mass.

The result is derived from fundamental classical mechanics laws.

Abstract

On each FRW metric, there exist a redshift for massive particles, analogous to that of photons, but depending on the mass. This is a simple consequence of the fundamental laws of Classical Mechanics.
