Homogeneous and Isotropic Charge Densities to Accelerate the Universe

TL;DR

This paper proposes a mechanism where giving a small mass to a force-carrying particle allows for a homogeneous and isotropic charge distribution, potentially explaining a phase of accelerated cosmic expansion.

Contribution

It introduces a novel approach of endowing force carriers with a small mass to overcome theoretical obstacles in homogeneous charge distributions in cosmology.

Findings

Massive force carriers enable homogeneous charge distributions.

This mechanism could trigger cosmological acceleration.

Potential relevance to dark energy phenomena.

Abstract

Various theoretical obstacles are associated with a homogeneous and isotropic distribution of ``charge'' which is subject to a repulsive, long-range force. We show how these can be overcome, for all practical purposes, by the simple device of endowing the particle which carries the force with a small mass. The resulting situation may be relevant to a phase of cosmological acceleration which is triggered by the approach to masslessness of such a force carrier.
