Nobel prize winner Richard Feynman explains in his sum over histories interpretation of Quantum Mechanics that photons go where time is least. If we consider that EMF are a lot stronger (in force magnitude) than gravity and if a magnet is emitting massive numbers of virtual photons, do we know if then, the magnet is loosing mass somehow in the process (a small but significant amount of mass being accelerated to the speed of light) ? If yes, where is that mass going or converting to ? Energy ? Finally, can the magnetic field around a magnet be seen as a curvature of space time ?
