“If MWI is true, then all the possibilities in which the universal wave function can split are realized, and there will be branches where I live for a very, very long time. Out of those branches where I am ‘quantum immortal’, those where the immortality is due to normal occurences will be much more probable than those where the law of (classical) physics are explicitly violated. For example, in the branches where I do not die hit by a bowling ball in the head, those where I simply decide not to go bowling are more probable than those where the ball simply stops mid-air or tunnels through my body.”
That summarizes the “what” of the idea. The “why” part is that classical physics violations are improbable so timelines with lots of classical physics violations would be improbable.
Well, it falls under the very known problem of any MWI: how can we say that some branch is improbable if all are realized? Unless you reverse it: a branch is more improbable the more it violates classical mechanics.
Is this a correct summary of your idea?
