The point isn't if I or others are worried about paradoxes. Being worried has nothing to do with it. The point is the universe doesn't seem to make sense or conform to our way of thinking. Not that it has to or should. The point is trying to figure out why things are the way they are is mind boggling. The world would be a very different place without mystery.

It is hard to give a definition to the word exists. What exists is based upon our perception which can be flawed. As far as I know quantum mechanics says that a particle can exist in many places at once. It doesn't pop into existance till we as observe it. Like bouncing a ball. It can exist in many places at once but once you observe it well that is when it comes into existance. That is the gist of what I got from the show. Not that I agree with it or that it makes any sense to me at all. The way I look at it if I bounce the ball it is going to react exactly the same way if I bounce it in the same manner every time. Me obersving the ball should have no effect on which of the many places it can exist in. If I bounce the ball it should rebound and head upwards back towards my hand. From what I remember the show suggested that is only one possibility and the ball could behave much differently and appear and behave in a manner contrary to the forces I put on it. I would say that is impossible or at least does not make sense to me
