WebAs a consequence of Einstein’s theory of special relativity, it is a known fact that photons, which are travelling at the speed of light, do not have any mass. A photon, however, does still have momentum, but how exactly?

WebAug 31, 1998 · The debate about the conventionality of simultaneity is usually carried on within the framework of the special theory of relativity.
