This is a great writeup. Since humans can't really grasp the concept of infinity, it would be worth considering that the Universe could be only a small fraction of an even bigger Universe that exists alongside the one we inhabit, and that there could be infact multiple Universes. A sort of fractal Universe that never ends and has all possible realities.
