Photons, their gravity and the speed of this gravity

 In my previous article I studied a photon and its mass. note that the waves of its gravity surrounds the pontoon. There is therefore a time chosen for the direction of the waves of gravity in front of him and behind him. These waves have the main characteristic of circulating at the speed of light, then emitted by the photons itself; But they, the wavelets, also have their own speeds that are just as fast. By design the wave in front of it moves in squares the speed of light over a very short distance.
