Einstein’s special relativity describes what happens to our space and time when matter moves but doesn’t say why it is so. According to quantum realism, light is quantum wave repeatedly spreading and matter is a quantum standing wave repeatedly restarting. Hence matter is inherently stationary while light is inherently moving. Since a standing wave doesn’t “move” as a spreading wave does, quantum realism faces the odd question “How does matter, as an inherently stationary wave, move at all?“
