If two worlds within this everything are contradictory or not consistent with each other, with no common ground, how exactly do they interact? I feel two such worlds must be independent entities within the set. This is different from the case of universes which may be linked by wormholes or MWI splittings or whatever. > > Furthermore, I imagine there is a single program that runs the whole > universe, and that we can know that program exactly. > > I'm not sure what Godel is doing here. > I imagine all possible programs for all possible universes. If there were a single program running the whole show, I would ask, why that program? As I mentioned in my reply to scerir, we can't avoid self-referential problems, however, if we try to represent or describe ourselves. > > Adopting that perspective, we should be able to justify that a > > simulation of our universe does not appear overly fine-tuned.
