*You miss the point. If the task is done in discrete steps as I described, which is apriori conceivable, motion is impossible. So, since motion surely seems demonstrable, why can't the task be done as I described? Answer; because space isn't infinitely divisible. If you check Wiki on Zeno Paradox and review the solutions offered through history, Henri Bergson came to the same conclusion I have offered, but he didn't extend it far enough.
