Eventually, if comp is true, the first one (the result of divergence from a common physical reality) must be explain through the second one (the result of phenomenological divergence, common for the guy before the split). All right? (this of course use step 7, and is not relevant at step 3) Bruno Terren In other words, so long as what I experience is identical, relative to each possible explanation of the phenomena (e.g. aliens / military prototype / atmospheric disturbance / holographic projection / etc), does that not entail computational equivalence among the potential continuations, even if the measure would differ among them?

Or the UFO belongs to a normal dream, in which case you will wake up, in the normal histories. Or the UFO is based on more rare computations, and the probability that you belong to them will drop down. Naively, what you expect is determined by the mass of computations going through your state. Although the rare experience seems as much real than the normal one, they are relatively rare. Even if you find yourself in one, from there you should bet on the normal continuations starting from that non normal situation. Similarly, you should never bet on a non normal computation, unless you die or are on drugs. Basically it is like the lottery: you should not expect to win the biggest gain, despite you cannot rule out the possibility. In our case, all finite computations may be ruled out, as they have a (naive) measure null, compared to infinite computations multiplied by (dovetailing on) the real numbers. Empirically Nature used a random oracle to get that self-multiplication right, and we can expect this to be proved necessary for the comp-measure measure. Now, that reasoning is a bit naive, and it is virtually impossible to count the computations, or even to recognize them in some 3p way.

Re: FPI possible continuations
Hi John, I don't mean to signify any particular ontological commitments when I refer to UFOs or any other feature of our experience. I'm comfortable with the uncertainty entailed by the skeptic's position. At the end of the day if we want to communicate, we need to use a shared language that hopefully activates in the listener the concepts we are trying to communicate. For the question I asked, it's not important whether those features of reality are really there, only that they present to our experience in identical ways; so this would allow dreams, hallucinations, and so on, as well as the features we take for granted as being real in the sense of being independently verifiable (in principle if not in practice).

Re: FPI possible continuations
Le 20 juil. 2015 23:14, Telmo Menezes te...@telmomenezes.com a écrit : Hi Terren, I won't try to answer but instead increase the scope of the question. Could it also apply to the past? Could there be many (infinite?) possible histories that lead to the current state of affairs, but until you learn about, say, the Mongol invasions then the Mongol invasions are just a possibility? I think it is, as measure is a relative thing, it echoes also the memory erasure experiment that Saibal Mitra I think once told. So yes any moment has multiple past as well as multiple futures. Whatever the relative measure of each, each moment is as real as any other. Quentin Cheers, Telmo.
