I don't see why one would want to go back, but there are still copies left in ordinary universes, there are universes in which the probability to win will return to normal after a while. One should thus be able to go back using a suicide machine. Also one could use memory erasure to go

I had the set of all possible universes in mind. But, as I wrote earlier (in August), the set of all possible universes is contained in the MWI. The reason is that there is a nonzero probability that you are be simulated by a computer. This computer could run any program. Saibal Charles

Dear Saibal, you misunderstood my post. I did not ask about "technicalities" of your sci-fi, I simply suggested that you may not "play" to get from here to there, but are "here" by a play from "over there". Simply humor, nothing else. John I don't see why one would want to go
