Every Mathematical Theory Is Held Inside a Physical Substrate

Zeno’s paradox is about the domain of pure mathematics. But we don’t live in a world of pure mathematics; we live in a world of physics. And if the physics says that we can transverse an infinite number of points in a finite amount of time, then that’s what we’ll do regardless of the mathematics says.

There goes my solution for Zeno’s paradox, which says before you can get all the way somewhere, you have to get halfway there. And before you can get halfway there, you have to get a quarter of the way there, and therefore, you’ll never get there.

Every mathematical theory is held inside a physical substrate of a brain or a computer. You're always bound by the laws of physics and these pure, abstract domains may have no mappings to reality.
