This issue was canvassed under the name "no cul-de-sac conjecture" in
the list. Bruno claims to have proved this conjecture in his modal
world logic. I tried to do this using a more conventional formulation
of QM - it seemed to be related to unitarity of quantum processes -
but I have to say I haven't succeeded in this.
An interesting point was made that black holes exhibit nonunitary
evolution, which has implications for those wishing an exit from
quantum immortality :)
Cheers
