CHAPTER

The Principle of Computational Equivalence

The ultimate fact about the universe is that it doesn't depend on specific rules. The things that happen in the universe are the kinds of computations that the principle of computational equivalence says should happen. We don't have a sort of connection to what's happening there, so we don't know how our brains work. And this idea that you can have these different kind of ruele reference frames, these different description languages for the universe makes me realize I used to think aliens experience the same physics as us. But now I've realized it isn't true. They can have a different ruele frame and end up with a descriptions of the universe that is utterly incoherent with ours.
