In the quantum suicide experiment, if many-worlds is true you'd end up miraculously surviving any suicide attempt. This forces you into an unlikely version of the universe, and each time you repeat it'd be more and more unlikely. Ok...now would it not be true that the nature of your experiment can determine the likelihood of the universe in which you'd find yourself? Pointing a gun at your head and firing will produce a universe in which you survive because the gun may jam, or the bullet may miss a vital area. That's unlikely but not "extremely" unlikely. But what if you change the method of suicide so that only a bizarre event can still keep you alive. What if you directed a 100 mile wide asteroid toward the earth so it landed on your head? Any version in which you'd survive this would contain an extremely odd and unlikely scenario. Perhaps the only way you'd survive is if aliens intervened and made a protective shell around you. By doing this though, you are forcing yourself into an extremely unlikely and unusual version of the universe. Perhaps, if you are smart enough and with enough planning you could arrange a suicide method that produced a survival-scenario universe of your liking in which you were a billionaire, or in which aliens announced themselves, or whatever you liked. You could engineer the resulting universe by the nature of your suicide attempt. You could force extremely unlikely events to occur. Any thoughts?
