If movement is a property of matter, there is no reason why it can’t just go faster and faster, but special relativity requires it to go slower than light, and common sense can’t explain why. But if light is a processing wave spreading on a network, its maximum movement rate depends how often the network refreshes, so the speed of light depends on the speed of space. Yet if matter is the same processing as a standing wave, it should be inherently stationary, not inherently move like light. This is why work is needed to move matter and is needed to stop light moving, but how then does matter move at all? Quantum theory suggests that it is because all matter trembles.
