In measure theory ( http://en.wikipedia.org/wiki/Measure_(mathematics) ) just because there are an infinite number does not mean they are equal. Your measure each time you pull the trigger in the quantum gun is (approximately) halved.

Your relative measure on the continuations where you survive remains constant and equal to one. We cannot count the cul-de-sac reality (and that is why Bp & Dt can give a quantum measure). Some absolute measure does not make sense.

Why not? It measures something different, but I don't see why it "doesn't make sense".

Describe an experience which gives sense to absolute measure.

I assume you mean "experiment" (although an experience would also be interesting :)

Gosh, someone told me that was the same thing. So you agree that experiences are 1p-experiment, and that experiment = 3p-experience?



In an uncountably infinite multiverse, the relative measure of me, humanity, Earth, the galaxy and probably the Hubble sphere is effectively zero.

This has no meaning to me. Only relative measure makes senses.




At least, I think it is. In a quantised multiverse which allows every instance of a finite number of 'worlds' to exist (a very large number, of course) then the absolute measure of, say, me is finite (though very small),

I really cannot make any sense of that.

Anyway, if you are Turing emulable, you are plausibly distributed on a continuum of (infinite) computations. And you have no absolute measure.




and one might in principle be able to work out what it is. But in a quantised multiverse I'm not sure QTI would hold.

OK. In a quantized multiverse, assuming we know our substitution level, one could build an annihilator which guarantied you disappear in all your accessible worlds! But you know that things are reversible, all right. That does not make sense, although it is hard to judge this with comp, despite a shadow of symmetry in all directions might appear at his core physics.




Or can the multiverse be quantised in that sense?

We just did. Oops!
