I was thinking of such theories as Alexei Starobinsky/Alan Guth's 'daughter universe' theory, in which a false vacuum spot creates a wormhole with a bubble wall on the end of it that pops off to create another universe. Or Alexander Vilenkin's 'eternal inflation' theory, which posits repeat 'big bangs' that duplicate our own. Or Andrei Linde's 'self-reproducing' theory that involves additional universes in other dimensions. I haven't heard how Schoredinger's Cat applies to these theories, because they only posit additional universes, not additional universes that violate the laws of our own universe. When you think about it, we simply do not know what exists 'outside' of our own universe, or whether indeed we live in the only one. It may be that if we can come to an understanding of the universe that we live in, we would then understand other universes that do exist, if any.
