Ok, speculatively jumping into the Tegmark book, which I am plodding
through and his
4 levels of the multiverse, I need to throw out this question. Is it even
possible,
in principle, to physically traverse into another universe, a parallel
universe, and
then back again? I do not mran in the David Deutsch sense of performing
cross cosmic
quantum calculations, but directly, mollecularly, boots on the ground,
traveling
there and back again?
Molecularly, I'd say no, but consciously I'd say yes. If we froze you on Earth, and then
coincidentally Aliens 100 trillion ly away from us made an exact version out of you out
of matter they had on hand, and then they thawed you, you would travel these 100
trillion ly. This journey is impossible for matter or energy to make, impossible for
anything physical, yet your consciousness did it. For the same reason, someone in an
altogether different physical universe could do the same thing and enable you to travel
there. There would be no causal link, however, to whatever memories you formed in that
universe and whatever version of you we create to unthaw and bring you back, it would be
again an entire coincidence for us to get it just right so the one we thaw matches the
one the aliens in the distant land decided to freeze.
In a sense, we are performing these traversals all the time, but only between distant
universes similar enough to the one we are in a moment before, that we don't notice it.
You might be sitting there quietly in Earth #313812031 one moment, then the next instant
you are actually on Earth #173119389 (which was an Earth that reappeared after 10^200
cyclical big crunch and big bang cycles) from the moment you were just in.
But then you've made incomprehensible nonsense of what is meant by "you".
