"But Tegmark goes further. He doesn't say that the universe is "isomorphic" to a mathematical structure; he says that it *is* that structure, that its physical and mathematical existence are the same thing."
I can see the appeal. If the universe ever *does* prove to be isomorphic to a mathematical structure (and I'm sure that's a long, long, long way from being proved at present) - by which I mean, if the universe is *exactly described* by said structure, with nothing else needed to completely describe reality - at that point, at least, I would take Max's MUH seriously, if only because Ockham's razor would indicate there was no point in hypothesising the existence of two things that are exactly isomosphic. However we are a long way from that point, and I imagine the nature of knowledge and measurement and so on mean that we can never actually reach it with 100% certainty.
