# A new bifurcation in the Universe

## TL;DR

This paper explores a cosmological model combining general relativity with a non-minimally coupled electromagnetic field, revealing a bifurcation and states with zero total electromagnetic energy, challenging traditional action-reaction principles.

## Contribution

It introduces a novel bifurcation in cosmological solutions involving non-minimal electromagnetic coupling and identifies states with null combined electromagnetic energy.

## Key findings

- Discovery of a bifurcation in the cosmological framework
- Existence of states with zero total electromagnetic energy
- Violation of the action-reaction principle in this context

## Abstract

We show that the combined system of general relativity with a non minimally coupled electromagnetic field presents a bifurcation in a cosmical framework driven by a cosmological constant. In the same framework we show the existence of states such that the resulting combined energy (the sum of the minimally and the non minimally coupled energy momentum tensor of the electromagnetic field) vanishes in a sort of violation of the action-reaction principle.
