Re: Travelling to a different universe
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 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 back. Saibal John Mikes wrote: SNIP

A correction to my model corrected: Near the end it should say: >Evolving universes must be isomorphic to a portion of one of these successive manifest counterfactuals. It is not required that a particular universe always be isomorphic the counterfactual at a given level of the nesting. Such a requirement would be a vast correspondence table of information that can not [should not] be in the Everything. > The nesting would allow an infinite number of such universes. Hal

John Mikes Suppose that every week I subject myself to a suicide experiment. I use a suicide machine to win that weeks lottery. After a few years I will have won hundreds of times in succession. Now there exists a class of universes, with a very low measure, in which the laws of physics are such that I am guaranteed to win. The probability that I find myself in such a universe will have increased substantially after each experiment. After a few years I will be sure to live in such a universe. It would be easy to check, all I would have to do is to buy a ticket and see if I have won without using the suicide machine. Saibal

Some people will sell one of their kidneys for just a few thousand dollars. If I were a multi-multi-multi-billionaire I should be able to buy a kidney for me after the operation.

Re: Travelling to a different universe
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 Goodwin wrote: > I can't see this.
