Then therefore, if the possibilities are endless, a creator also exists?I don't think your sums add up.
There are an infinite set of types of infinity and each set is infinitely bigger than the preceding one, the size being called cardinality. The lowest cardinality called aleph 0 is also called 'countable infinity'' this includes the set of natural numbers because you can start counting them, the next size up is called uncountable infinity or the continuum infinity, this set includes all rational numbers. Its's easy to visualise with a ruler. The countable infinity is whole number divisions 1, 2, 3, etc while the continuum infinity is represented by the space between the whole numbers. Each of these spaces can be divided indefinitely, you can always divide any division indefinitely, and this continuum infinity is infinitely bigger than the countable infinity. Don't ask me what the next level is, I don't know.
Before any one jumps down my throat, I'm not an expert but I think I've got the essence of it right if not the details.
Back to your sums. An infinite number of finite universes (u) belong to the countable infinite set ie the smallest cardinality. The number of variations (or paths and potentials as you put it) for each universe (u) belongs to the continuum infinity and is thus infinitely bigger than the countable infinity of finite universes (u) and so won't fit in. All possible variations cant fit in all at once in the Universe (U).
Another way of looking at it is to imagine that I can always add another unique universe (u) to your Universe (U) because there's an infinitely greater number of variations for me to choose from. So, because another different universe (u) can always be added to your Universe (U) proves it didn't contain all possibilities to start with, and nor can it ever do so.
The bottom line is that our Universe (U) is only playing out one scenario of a continuum type infinity of other possible scenarios. This really bugs me, I'm lost from here on.
