How many universes in multiverse?

[t-dvty-prjct]

So, provided that the multiverse does in fact exist, are there an infinite number of universes in this multiverse or just a large amount? I've heard that the number is infinite and I've also heard the number is around 10^10^10^7. Also, if the number of universes is finite, how many universes are there, or if the multiverse is infinite, does that mean that any probability based situations could be dissmissed as coincidence as a result of an infinite number of chances for such a situation to occur?

I wrote and published a theory on the subject recently. Although I use the term "universum" instead of "multiverse". It's a mixture of the words "universe" and "sum". Well hard to say how many but I would advise you to read it since you like the subject.

That depends on the theory that contains multiverses eg many worlds, eternal inflation etc etc. For the ones I am aware of it's very very large - for all practical purposes infinite - but not actually infinite. There may be some that are actually infinite - but I am not aware of them.

So I guess "Transfinite" a concept proposed by Georg Cantor would by definition fit this perfectly.

According to my-go-to Professor in New Zealand on Quantum Mechanics matters:

A good example of this is a macroscopic magnet. A macroscopic magnet is formed from very many microscopic magnets, i.e., the magnetic atoms from which the magnetic material is formed. When the magnet is hot, all the little atomic magnets are randomly aligned, so the macroscopic magnet is not magnetized. If we cool things down, eventually a temperature is reached at which all the little atomic magnets line up with one another, so the macroscopic magnet is then magnetized. This lining up can take place in any direction; this, there are infinitely many possible alignments of the atomic magnets (physical configurations). Within quantum mechanics we can have a superposition of all those possibilities.

... so if MWI is correct, there'd be an infinite number of universes containing the various alignments of atomic magnets.

I was under the impression that there was only a finite number of configurations within a finite/bounded space? Hence the Poincare recurrence theorem.

None of the answers are true, the multiverse theory/theories are flawed.
