I cannot understand how things move. Consider the leading point of a pool ball: for the ball to move, that leading point has to dematerialise from Point A and materialise at Point B. When I attempt to explain this to others, they invariably respond with something along the lines of 'But it just moves a small distance'. This is what causes me a problem because, regardless of the distance moved, small or large, the leading edge of the pool ball must be in one place at one moment, and the next moment, it is in a different place. What else can this be other than dematerialisation / materialisation. Which, as I understand, is not possible. So how do things move?
