communication betwen photons and gravity

According to symmetry, a ghost photon works with a photon and therefore communicates with it. Aside from the only common element, is the gravity of the photons themselves. Indeed, the speed of light is the maximum speed. therefore the gravity waves emitted by the photon itself circulate at the same speed as it and are around it. as a result, the waves of light from photon A arrive at the phantom photon (B) before the other waves of light itself at the level of phantom photons: It is therefore the gravity waves of the photons which is the mode of communication in transparent medium.
