But what does that mean? How do they "compete" and what are they competing for. What does "emerge" mean? This is explained in step 7 already. Imagine that you want to evaluate if an apple will hit the ground when falling. You are in the state S just at the moment you let the apple free. What happens next is determined by all computations going through your state S. The probability that the apple hits the grounds is given (roughly) by the measure of the histories/computation-seen-from-the-1p where the apple hits the ground dividec by the measure on all computations (the measure one which we have shown to be quantum logical). I identify here computation with the universal machine which execute that computation. By the extreme redundancy of the work of the UD in arithmetic, there will be an infinity, and they compete in the sense of the first person indeterminacy, a bit like in the WM duplication, except that the multiplication is by aleph_zero, or 2^aleph_0, instead of 2. IT *is* more complex than that, but I want give the basic idea. The lath are difficult, and only the "yes/no" logic is given. The other probabilities needs the equiavent of Gleason theorem, which is assured if one of the S4GRZ1, or X1* or Z1* logic is linear enough, say. It emerges in the sense that all there is are 0, s(0), ..., structured by the + and * laws, and the self-referential logic which are justified by the + and * laws, as shown by Gödel, Löb & Co.

The physical reality is what emerges in the limit of a competition between infinities of universal numbers operating below our substitution level. Above that level what remains locally are competition between finitely many universal numbers, like gaz, cells, brains, arithmetic, computers and programming languages. In a sense, the UD is worse than Boltzman brain, but then arithmetic justifies the intricacy and structure-full of the possible solution. The understandable has a border, and it put some structure on the non understandable. Physicalism remains possible, but at the price of needing to assume that consciousness cannot be an invariant of any recursive permutation even with oracles. That would appear only as trying to put even more away the *person* under the rug. Is simpler to listen to the (Löbian) universal number, to see that there is a person, in a sense close to the analysis of Parmenides, taking the first five Parmenides positive hypotheses as the five (arithmetical, p is an arbitrary arithmetical senetence, and [] is Gödel's beweisbar) hypostases: p, []p, []p & p, []p & <>p, []p & p & <>p. That describes 5 fundamental ways the universal number can see itself relatively to some universal number chosen, in my case I illustrate with three of them: Robinson Arithmetic, SK-combinators, a (precise) universal diophantine polynomial equation(s). [] is Gödel's beweisbar predicate. It is justified because we limit ourselves on machines which would derived correctly their own functioning in case they would bet correctly to their substitution level (which no machine can know- for-sure). It is "truly" universal, about the way universal numbers are related. It looks already elementary arithmetic defines a universal person lost in a highly mathematically structured web of dreams, obeying laws, from which we can at least test the physics obtained. This illustrates at the least that a form of subjectivism (albeit not a human one, but a "universal number" one) is empirically testable. It generalizes Everett in the sense that it takes all computations into account, not just the quantum one, which needs to be retrieved from the phenomenal hypostases. Inflation of possibilities is thread for all kind of modal realism,but the other extreme leads to solipsism. Digital Mechanism and computer science gives the tool to study a non trvial intermediate between the inflation and the collapse of realities.
