I believe that all possible universes exist, and I agree that this belief
entails all the conclusions that you have listed. However, I can't be
completely sure about all this. It certainly isn't something considered to
be true beyond reasonable doubt amongst physicists, so I don't think we
should be too dogmatic about it.
