The deeper we go the more objects we find that we can only describe using mathematics, for sure. That’s not the same as them being mathematics though. We don’t know what the essential nature of these objects is.

It is an interesting speculation, but it’s also possible it’s just confusing the map for the terrain.

If mathematics is the only way we know to describe them, then they might be mathematics. That seems like the simplest possible explanation, so that's probably why I suspect it's probably the correct.

It also seems like a comfortable answer to the question about about what's happening every time I cause wave function collapse and split the universe. I'm just creating a new mathematical structure.
