What about a single,

FWIW, in my view we live in
huge, but finite, expanding
hypersphere, meaning in any
direction, if go far enough,
you return to your starting
position. Many cosmologists
say it's flat and thus
infinite; not asymptotically
flat and therefore spatially
finite. Measurements cannot
distinguish the two
possibilities. I don't buy the
former since they also concede
it is finite in age. A
Multiverse might exist, and
that would likely be infinite
in space and time, with
erupting BB universes, some
like ours, most definitely
not. Like I said, FWIW. AG
OK, but is the *strangeness* of a
multiverse with multiple copies of
everything *in itself* an argument
against it?

FWIW, I don't buy the claim that an
infinite multiverse implies infinite
copies of everything. Has anyone
proved that? AG
If there are uncountable possibilities for
different universes, why should there be
any repetitions? I don't think infinite
repetitions has been proven, and I don't
believe it. AG
If a finite subset of the universe has only a
finite number of configurations and the
Cosmological Principle is correct, then every
finite subset should repeat. It might not; for
example, from a radius of 10^100 m out it
might be just be vacuum forever, or Donald
Trump dolls.

Our universe might be finite, but the parameter
variations of possible universes might be
uncountable. If so, there's no reason to think the
parameters characterizing our universe will come
again in a random process. AG
Think of it this way; if our universe is represented
by some number on the real line, and you throw darts
randomly at something isomorphic to the real line,
what's the chance of the dart landing on the number
representing our universe?. ANSWER: ZERO. AG
But the structures we may be interested in are finite. I
feel that I am the same person from moment to moment
despite multiple changes in my body that are grossly
observable, so changes in the millionth decimal place of
some parameter won't bother me. The dart has to land on a
blob, not on a real number.

Don't you like thought experiments? I have shown that the
parameters of our universe won't come up in a random process
if the possibilities are uncountable (and possibly even if
they're countable). Maybe you prefer a theory where Joe the
Plumber shoots a single electron at a double slit and creates
an uncountable number of identical universe except for the
variation in outcomes. Does this make more sense to you? AG
You might get universes close to ours, but even this would be
hugely unlikely given the uncountable assumed number of
possibilities, and even a close call might mean no hit wiping the
dinos. No exact repeats! AG
Quantum Mechanics informs us that there is a finite amount of
information <https://en.wikipedia.org/wiki/Bekenstein_bound> that can
be stored within a finite volume of space having a finite energy.
