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 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 trembling hand creates a fuzzy patch. Matter then isn’t inert but constantly jiggling, like quivering rod.
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 reach the moon in about a second, but it can’t. Matter restarts as often as light moves but if it teleported every time, it would have no life, so it trembles slower than light moves. Yet atoms still jiggle at a fantastic rate, so why don’t they move as light does? They don’t because if they tremble the same in every direction, these tiny movements cancel to give no overall effect, but if something alters that, they will move.
That matter constantly trembles means it doesn’t need a push to make it move, as it is already moving, just equally in every direction. All it needs though to move in our terms is to tremble one way more often, and making its distribution stronger one way can do that.
