WebEven though photons have no mass, they still interact with gravity because they have energy, and energy is affected by gravity. When light passes near a massive object like a star or black hole, the gravity bends space-time, causing the light to change its path. This is called gravitational lensing. WebPhoton definition, a quantum of electromagnetic radiation, usually considered as an elementary particle that is its own antiparticle and that has zero rest mass and charge and a spin of one.
