Simple. Shooting yourself with a gun or whatever means you use to end
in one universe does not guarranttee that you do not grow in all other
universes. Unless the laws of physics differ across the multiverse,
understand to be incorrect, your copies will grow old and die in every
I think it would help if you put your comment beneath whatever you were
replying to. :)
However, assuming I understand what you're saying I will attempt a reply...
The laws of physics don't /mandate/ growing old and dying, they just make it
overwhelmingly likely. But in a multiverse everything happens, even
That's another dubious popularization. Certainly weird things can happen
in a QM
world. But *everything*? There are still conservation laws, superselection
limited speed of signaling. Repeating measurement doesn't produce "every"
it produces the same eigenvalue as before. Many QM processes are
one world, c.f. arXiv:quant-ph/070212v1.
I apologise for my over hasty phraseology. I meant to say everything that is physically
possible happens - i.e. all physically possible outcomes of each (apparently
probabalistic) quantum event. I didn't mean to imply that /physically impossible/ things
happen (and it would have been nice if you'd done me the courtesy of thinking that
perhaps that was what I meant, rather than assuming that "oh, she must be spouting
dubious popularisations!" as you appear to have done.)
Sorry. Didn't mean to offend. But it's a point that bothers me about a lot of these
"everything" theories. Yes, they only mean everything that is possible - but that could
be a big hole in theory when you start to talk about really strange things. For example,
holographic theory (combined with QM) limits the amount of information within a Hubble
radius. It's not immediately obvious whether that prohibits some evolution of the quantum
state or not, but it's plausible that it does.
