Specific electromagnetic configurations could potentially reverse the flow of time by turning future directions into the past.
Time is generally understood to move in one direction, but these electromagnetic gauge transformations might break that rule. This theory suggests that a specific field setup can flip a timelike vector from future-directed to past-directed. It challenges the fundamental laws of causality that govern how we perceive the universe. If this configuration can be physically realized, it would be a radical departure from everything we know about spacetime. This research pushes the boundaries of what is possible within the standard framework of electromagnetism.
Full spacetime inversion generated by electromagnetic Abelian gauge transformations
arXiv · 2605.00867
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 alt
