My understanding is that any uniform motion ( according to relativity) can be considered stationary. For example if object A is moving at a constant velocity, it is as legitimate to say that it is stationary as to say that it is in motion. Why cannot a photon, moving at the speed of light and at a constant velocity ,be considered stationary? In that case according to the photon's "viewpoint" the space it traverses is non existent. This seems to me to coincide with QM's idea of non-locality. One more related question. Why is the speed of light 186,282 mps? Why not 186,283mps? To make my point more dramatic, suppose that photons of light in a vacuum traveled at 45 miles per hour. Would time dilation effects then be noticeable at 20 miles per hour? I would guess not ( I could be wrong, I'm not a physicist, just a curious layman) . Then, my question becomes why do photons move at the exact speed that time ( for them) ceases?
