If I spend long enough, I can count whole numbers to infinity. I cannot possibly count all the numbers between 0 and 1. This so why real numbers have a whole different magnitude of infinity from integers.

Thanks, this is helpful.

So first we need to answer does math follow physics or does physics follow math?

If math follows physics, and the physics is changing across universes in the multiverse in question, then no you're assertion is wrong.

If physics follows math, then we would have to go up the level higher, and we're not talking about that right now.
