If comp is true, the "physical" universe is not a mathematical possibility. It is something much more deeply related to mathematics. With the comp hyp "physical universes" emerge necessarily from the interference of all mathematical possibilities, and the physical laws are the invariant of such possibilities for their internal local observers. This entails we *are* in touch with the other universes, and they do exist from our point of view. It is just an open problem if QM really confirms this easily (cf UDA+movie-graph) derivable, from comp, fact. This is what I try to explain in this list since the beginning (and elsewhere before). Tegmark and Schmidhuber have missed this fundamental point. Schmidhuber missed it by his refusal to distinguish between 1 and 3 person points of view, and Tegmark missed it by not postulating the comp hyp (making a little bit "physics" just a geography.
