Full spacetime inversion generated by electromagnetic Abelian gauge transformations

TL;DR

This paper explores how electromagnetic gauge transformations can induce full spacetime inversions, including reversing the flow of time, which has not been previously discussed.

Contribution

It demonstrates that electromagnetic gauge transformations can generate full spacetime inversions and reverse the flow of time within a region of spacetime.

Findings

Electromagnetic gauge transformations can alter the physical kinematic nature of spacetime.

A field configuration can reverse the flow of time, turning future-directed vectors into past-directed vectors.

Experiments for achieving time reversal via gauge transformations are proposed as novel.

Abstract

In a previous manuscript we addressed the possibility of generating a reflection in a region of spacetime inside a null surface under electromagnetic gauge transformations. In this manuscript we will deal with the possibility of full inversions in a region of spacetime inside a null surface under electromagnetic gauge transformations. Since new tetrads whose construction depends on electromagnetic gauge were introduced it has been proved that the physical kinematic nature of spacetime can be altered as proved previously. In this case we will see how to create a field configuration that will reverse the flow of time. We will prove that we can turn a future directed timelike vector into a past directed timelike vector by physical means. Experiments devised in order to achieve time reversal or full inversion have been never discussed before.
