Description

An alternative formulation of classical electromagnetism relying on torsion in metrically flat spacetime in four dimensions is presented. Unification with gravitation is then obtained as a direct consequence of the extension to the more general case of metrically curved spacetime. A propagating equation for the electromagnetic potential is derived and discussed. In the same context, it is also shown that a second kind of photon can be predicted (which could be the so-called “Dark Photon”) and how it can be distinguished from the known photon in presence of gravitation.
