_ __Until you detect a THIS WORLD observer splitting_ [....]
One world contains an Alan Grayson that sees the electron go left,
another world is absolutely identical in every way except that it
contains a Alan Grayson that sees the electron go right. So you
tell me, which of those 2 worlds is "THIS WORLD"?
It's the world where a living being can observe the trials being
measured. The other world is in your imagination (if you believe in
the MWI). AG
FWIW, why, as someone with a strongly empirical interpretation of
physics, do you give THIS world, the one we can directly observe, and
the OTHER world, which is an imaginary construct, allegedly implied by
mathematics, equal ontological status? AG
This World is selected at random from the set of all possible Worlds
using the Born rule probabilities. And we can infer that this is the
case from observations, although that doesn't rigorously prove that the
other Worlds are real. It's similar to inferring that the World as we
think it existed in 1985 did indeed exist, but we can never prove this,
because God could have created the World today with false memories about
a hypothetical 1985 that never really existed. There is no experiment we
can do to rigorously rule out that possibility. So, if there are
believers in the theory that God created the World yesterday, then there
is no experimental result available that will convince them that they
are wrong. The same is true about the MWI, albeit that the alternative
theories in that case are a bit less bizarre.
