Possible Connection between Dark Energy and Electromagnetic Interactions

TL;DR

This paper explores a theoretical model linking dark energy to electromagnetic interactions, proposing that photon coupling to gravity could generate cosmic acceleration without giving photons mass.

Contribution

It introduces a novel model where dark energy arises from electromagnetic field coupling to gravity, with a Higgs-like mechanism ensuring photon mass remains zero.

Findings

Photon coupling to gravity can produce exponential cosmic expansion.

The model predicts a massless photon consistent with observations.

Dark energy may originate from electromagnetic scalar potential effects.

Abstract

This paper has been withdrawn by the authors. Please see [arXiv:1208.3224]. We investigate a model where dark energy is caused by the photon field coupling to gravitation. The cosmological background expectation value of the electromagnetic scalar potential generates the Planck mass as well as causing an exponential expansion which is identified with dark energy. The Higgs-like mechanism for the vector potential predicts the photon mass to be exactly zero.
