> If current mathematics is unable to describe physics, then new mathematics is invented

Now suppose that this process stops. One day, mathematics describes physics. What does that mean? It means that some pencil-and-paper mathematics descriptions hint at an abstraction, and that abstraction is physics.

The mathematics which was used prior to that point was not the right one. That mathematics still corresponds to a universe, just not this one.

The idea is that every mathematical object is a universe (not to be confused with some representation of that object, like a definition in plain language, or a diagram, equation).

The world may be exactly the same category of thing as dodecahedron or pi. (Not in the category of pencil-and-paper description of such things; the category of those thing themselves.)

Now suppose that it doesn't stop. Suppose it can't stop.

Suppose no mathematical system is sufficient to describe any universe. It's always just a rough approximation.

Either could be true, I guess.
