I have a question I wanted to throw out.

"Superuniverse" theories of one type or another are currently a fashionable explanation for the characteristics of our observable universe. This is all well and good, although the lack of any observational possibilities, even in theory, leaves me rather ambivalent.

The thing is, "Wouldn't this Superuniverse, as well as all the other "bubble" universes like our own within in, be itself subject to varying forms of the laws of entropy? How could this not be so given the fact that one of the bubble universes it produced (ours) is subject to such laws? If the superuniverse is therefore subject to entropy, wouldn't it also be finite in some form, just like our "bubble" universe? If the superuniverse is finite in some form, does it really explain anything?
