I would expect that somewhere in the Multiverse, France still has a
king in 2015, and has a beard, and somewhere else where he doesn't.
If you are talking of a separate universe outside our Hubble volume
then you are going to have difficulty defining exactly what you mean
by 'now' or '2015'. The other worlds of the MWI are not even in the
same universe, so you are going to have even more difficulty in
assigning a truth value to the proposition.
Philosophical 'possible worlds' are quite distinct from multiverse
ideas.
Absolutely, but that is why it is interesting if some philosophical
hypothesis (comp) can force a relation between them, like making QM
the measure of the computation (in the "classical-Church-Turing" sense).
Then the math confirms this, as proved by the Löbian universal machine
itself, as on the p sigma_1, the first person variant of the 3p G
([]p), that is []p & p, []p & <>t, and []p & <>t & p, provides a
quantization (namely [i]<i>p, with [i] being the corresponding
modality of the variants).
I think that with comp, Heisenberg-Pauli-Fuchs are as much correct
than Everett. The quantum, and also themrmodynamic are already bridge
to a theory of mind, and with comp, eventually a theory of numbers and
other CT-universal systems.
