Been thinking about this for sometimes now, most people say photons doesn't have a mass, and in theory since photons travel the speed of light then it must either have no mass or always been traveling at the light. But if a photon doesn't have a mass then how can things such as black hole or even just a star with high enough gravitational force to bend light. My personal thinking is that photons might have a mass but so small that we can't measure, but seriously not sure. :P
