WebHow do photons have no mass? Why do photons have no mass? In short, the special theory of relativity predicts that photons do not have mass simply because they travel at the speed of light.This is also backed up by the theory of quantum electrodynamics, which predicts that photons cannot have mass as a result of U(1) -gauge symmetry. WebSince photons have zero rest mass then their energy is simply E = pc. The fact that light carries momentum is also verified by experiment.
