Electrodynamic effect of anisotropic expansions in the Universe

TL;DR

This paper proposes that anisotropic cosmic expansions modify electrodynamics, leading to observable effects such as polarization variations in electromagnetic radiation passing through regions with local anisotropic expansion, potentially explaining quasar polarization observations.

Contribution

It introduces a new electrodynamic effect caused by anisotropic expansion regions in the universe, linking local anisotropies to observable electromagnetic phenomena.

Findings

Prediction of polarization variation in electromagnetic radiation.

Possible explanation for observed quasar polarization.

Identification of regions with local anisotropic expansion.

Abstract

In the presence of anisotropic cosmic expansions at global or local scale the equations of electrodynamics in expanding space-time are modified and presented here. A new effect should arise in regions of local anisotropic expansion in a cosmologically isotropic background. These regions should naturally exist, being connected with scales decoupling from the Hubble flow. Possible observational consequences of this effect are suggested. In particular, I predict the appearance or variation of the polarization of electromagnetic radiation coming from or passing through these regions. This effect is observable and possibly already observed in the polarization of quasars.
