Hello everyone, I was thinking of the 4 forces and in particular of the gravity force. We know that black holes and their gravity force can bend light and light gets lost on black holes. How can the ipothetic particle of the graviton interact with the photon? I thought that if the interaction is real, the graviton must be not only faster than light to perceive the mass, but it also has to be smaller and photons should be able to interchange gravitons. I must be wrong, I know, but could anyone explain this to me?
