According to quantum theory, a point of matter doesn’t sit at a fixed point but trembles about its quantum distribution. Schrödinger deduced this quantum fuzziness from the Dirac equation and he called it zitterbewegung. Point matter is then indeed at a point but not always the same one, like a dot constantly redrawn by a painter whose hand trembles, so it appears as a fuzzy patch.
Light advances every quantum cycle, at about 1043 times a second, so it travels about 300 million meters in a second. If matter moved like this, rockets could go to the moon in about a second, but it can’t. Matter restarts as often as light moves but can’t teleport every time, or it would have no life, so matter trembles slower than light moves. Yet atoms still constantly jiggle about at a fantastic rate, so why don’t they move as light does? The answer lies in their quantum distribution. If it is symmetric, or equal in every direction, these tiny movements cancel out, so quantum trembling itself doesn’t make matter move.
But that matter constantly trembles means it don’t need a push to make it move, as it is already moving, just equally in every direction. It follows that if the quantum processing around matter becomes asymmetric, it will tremble one way more often, to move in our time. Matter will then move if the quantum field around it is stronger in one direction, so what could cause that?
