1. Is quantum physics the end of the story?
    No, it needs to work with general relativity and vice versa. That would be the beginning of the end.

  2. Shouldn't quantum physics add up?
    Uncertainty principally depresses me, but probability is it. It's position or velocity, not both.

    Take parallel worlds. Move A to B. Straight path? No, all possible paths, at once. Then, sum.

    Result: It adds up, sumwhat.
