MWI doesn't explain the probabilities.
So what would the probabilities be if MWI were true?
Undefined.
What would it be like to live in a world where probabilities were
undefined? Can
you reason that we don't live in a world with undefined probabilities and
therefore
we can't live in a multiverse?
Platonists just don't get it. Probabilities would be undefined by the
theory. They
would still be defined operationally in the laboratory.
Are you saying that in a multiverse (a concrete, infinite Tegmark Level One multiverse,
for example) there is no way to calculate the probabilities from first principles,
Not just in virtue of living in the multiverse. Since we can only access one universe, we
can only infer measures on a multiverse from some theory that relates the multiverse to
what we observe in our universe. I'm saying the SWE alone doesn't provide that theory.
Compare, for example, Susskind's idea of the landscape with 1e500 different physics. Are
those implied by the SWE? Our measure in them is essentially zero.
Brent
but nonetheless we could be living in such a world and would be able to measure
probabilities experimentally?
