If light moved by itself alone, it could just go faster and faster, but it doesn’t. Current physics knows that light moves at a fixed speed in space, but why isn’t clear. It is just given, but light as a wave of processing spreading on a network can only move as fast as the network passes it on. The speed of light in space is then 299,792,458 meters per second, no more and no less, because of how often space refreshes, so the speed of light is really the speed of space (3.2.4).
Similarly matter particles moving by themselves should be able to go at any speed, but special relativity makes them go slower than light, and common sense can’t say why. It also makes the speed of light constant however matter moves, so light from a fast rocket still leaves at the speed of light. Relativity says that light moves absolutely but matter moves relatively, but why is it so?
