WebOct 3, 2024 · An individual photon has mass zero, this means its four vector ( p x, p y, p z, E) has a "length" of zero. Can two photons added together have a mass larger than zero? Sure, unless they are collinear, the added four vectors will have an invariant mass. A good example is the pi0 particle which decays into two photons. WebOct 9, 2011 · In relativity ALL energy contributes to gravity, and so a photon has 0 mass yet it does have gravity and it can, and does, travel at c to the best of our knowledge.
