WebA photon is a type of elementary particle that primarily acts as a carrier of energy. An electron is a subatomic particle that is present in all atoms. A photon has no charge. It possesses a negative charge of magnitude 1.62 × 10 −19 coulomb. It has no rest mass. An electron has a mass of 9.19 × 10 -31 kilograms. WebJan 12, 2016 · What doesn’t really exist is Hawking radiation. For the stellar mass black holes, the time for this radiation to evaporate the black hole is 10 70 years, essentially infinite. In fact over the whole history of the universe just one high energy photon or particle would be emitted.

WebHowever, this fact does NOT mean the photon has "mass".
