I also don't think that 'Quantum Theory of Immortality' is correct in its conventional form. I do believe, however, that a different version is implied by James' Theory of Observer Moments. Since there exists a set S of observer moments, one element of which represents my state now, I will ''always'' find myself in some subset of S. This doesn't mean that I could outlive everyone. The observer moment: I am 10^1000000 years old is simply inconsistent with I am Saibal.

I posted earlier about an article by Caticha that explains how fundamental laws of physics (including notions such as time and space) can be derived from nothing more than an arbitrary probability distribution defined over some arbitrary set.

  Before I was blind but now I see.
  I was the one who came up with the expression, 'Quantum Theory of Immortality', and I now see that it's false - and all this stuff in this thread is based on the same mistake. See www.higgo.com/qti , a site dedicated to the idea.
  There is no 'you'. 'You' don't 'travel'. There are just different observer moments, some including 'I am Micky and I'm, sick'.
  Even thinking in your passe Newtonian terms, how can a universe in which 'you have a disease' be the same as one in which 'you do not have the disease', just because you don't know it?

  I see why Jacques gets so irritated by this type of thinking, but it's nice to see him back on the list now & then.

    *Phew!*; this afternoon I finally got round to reading the 190-odd messages I have received from this list....
    From: Saibal Mitra
      Instead of the previously discussed suicide experiments to test various
      versions of many-worlds theories, one might consider a different approach.
      By deleting certain sectors of one's memory one should be able to travel
      to different branches of the multiverse. Suppose you are diagnosed with
      a rare disease. You don't have complaints yet, but you will die
      within a year. If you could delete the information that you have this
      particular disease (and also the information that information has
      been deleted), branches in which you don't have the disease
      merge with the branches in which you do have the disease. So with
      very high probability you have travelled to a different branch.
    I don't know whether to be relieved or annoyed that I'm not the only person to think of this ;D.
     I'm guessing this is quite a common idea? Rats, I thought I was so great....
    I _did_ think of the following today, though:
     If you take this sort of thing one step further, an afterlife is inevitable; there will always be systems - however improbable - where the mind lives on. For instance, you could just be the victim of an hallucination, your mind could be downloaded, you could be miraculously cured, and other _much_ more bizzare ones. Since you won't be around to notice the worlds where you did die, they don't count, and you are effectively immortal. Or at least you will perceive yourself to live on, which is the same thing.
    When I thought of it, it seemed startlingly original and clever. Looking at the posts I have from this list, I'm beginning to suspect it's neither.... Anyhow, while this sort of wild thinking is wonderfully pure and cathartic, it never seems to lead anywhere with testable or useful implications. So far, anyway....
    What's the opinion here on which are more fundamental - minds or universes? I'd say they're both definable and hence exist de facto, and that each implies the other.
    Well, I'm new here. Is there anything I should know about this list? Apart from the fact that everyone's so terribly educated.... Feel free to go a bit OT ;).
