Richard: I am proposing that the finite 3D array of 10^90/cc compact space particles are a computer for implementing RA. I must have used the word emulation improperly. Bruno: You were correct. But the question remains. String theory is a theory inferred from observation. With computationalism, if string theory is the correct physics, we must show how to deduce it from RA, and we must justify why it win the measure "battle" in between all universal machines below our substitution level. String theory might be the answer, but it has yet to be extracted from its arithmetical subpart, to solve the mind-body problem. Indeed by UDA we have to do that, and the advantage is that we will get both the scientific communicable parts (through G and its intensional variants), and the "scientifically not scientific" incommunicable (+ the inexpressible) parts (through G* and its intensional variant). Richard: First of all, I do not think string theory comes from observationa, but that is beside the point. I agree that we have to deduce string theory from RA. But that inclueds deducing that a 3D array of 6d particles results. This array of particles may then become a universal machine that can deduce itself. Is not that something that you say machines do with comp?
