It's not crazy. I'm no physicist, but I understand the math of the Big bang is similar to that of a White hole.

What gets a little mind bending for me is the idea that the physics inside the black hole can differ slightly from the ancestor universe. So black holes will preferentially create descendant universes that prefer to create more black holes.

This is a different multiverse theory than the quantum many worlds theory. The limitation of quantum many worlds is that the physics doesn't change. But in the ancestor black hole many worlds theory it does.

When you put these together, you can get an even larger multiverse, where anything that can happen does happen, but only if the laws of physics allow for black holes. That may mean the Marvel Cinematic Universe, is out there somewhere, so long as those laws of physics allow for black holes. Right? Again not a physicist.

According To Tegmark's reasoning the MCU could be out there, black holes not a prerequisite but

"there are all sizes of infinity, some infinities are bigger than others. The infinity of Real numbers is bigger than the infinity of all positive numbers, and it should be noted that while the infinity of all positive numbers is infinite the number 3 only shows up in it once."

Not even close. There’s an infinite amount of numbers in between 0 and 1. But in an infinite multiverse for each of those numbers, you could never see 2.

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.
