    Infinite options does not mean all options. Eg in the set natural numbers 0-infinity the set of infinite numbers between 0-1 (or between any other 2 adjacent numbers) is absent.

    So you can definitely have an infinite multiverse where in all of them infinite multiverses exist.

      Infinite options does not mean all options.

      Right, as you said the natural numbers is an infinite set but it doesn’t contain fractional numbers between adjacent natural numbers. The set of natural numbers also doesn’t contain letters, or colors, or varieties of geese. You can even add other constraints to the set and still have an infinite set that contains even fewer possible values, like you could have the set of all natural numbers that don’t contain the digit 3.

      People make the mistake of thinking that an infinite set of universes means that there is every conceivable version of a universe out there, but that’s not the case. Murphy’s law says that anything that can happen will happen, but that means things are still constrained by what can happen. Reality is constrained by consistent logic, the most basic of which is the identity law, p = p. It is a contradiction for both p and ~p to be true, a violation of reality. So if the multiverse is a reality, it is a single reality that is self consistent, meaning there is no Universe in the multiverse for which there doesn’t exist a multiverse.

      Yes, even in an infinite multiverse, there is no universe where science_memes commenters have sex.

    The set of all possible universes does not include impossible universes. If you assume all possible universes exist, you’ve already eliminated universes that are the only universe as impossible.

    The multiverse either exists or it doesn’t. Individual universes have no influence over that.

    Infinite doesn’t mean everything. Infinite can include a repeating pattern, even a huge repeating pattern which seems random at first. Not everything you could possibly imagine would necessarily have to exist in the multiverse.

    And even if infinite and perfectly random, some things may just not be feasible and just not exist.

      In an infinite list of letters, every single book ever written, every word ever spoken (and to be written/spoken) should be present no?

      I guess the only caveat is that in an infinite universe certain physical laws could be universal (which would prevent eg any universe to break the speed of light)? But some version of me having hair past my 30s should certainly exist no?

      Or am I getting this completely wrong?

        This infinite list of letters could be "any random combination of letters EXCEPT when that makes the word “banana”. A subset of an infinite set can still be infinite.

        Infinite != all possibilities
