1) I have read that theory suggests infinite amount of universes and I have also read that the theory suggests a finite amount of universes. Which is the right one? If for every decision new universes are born, the number should be finite, right? 2) In quantum mechanical sense, is it correct to say that there is a probability (negligible of course) that all the atoms that I am made of could spontaneously travel one meter to my right (quantum tunneling?)?
