This is probably my favorite Kurzgesagt video, and as usual, 99% of the science is way over my head. I must also admit that this is one of those rare series (hello podcasts, love ya, but…) that uses a professional narrator to communicate. 🥳

Anyway, I like this set of hypotheses for ~three reasons–

1. The fundamental idea that the more massive a black hole is, the thinner it’s composite material, fascinates me. And that our own universe’s density of known matter matches very well against that idea. (our own universe, materially-speaking, is largely a soup of nothingness)

2. Suddenly the ‘multi-verse’ idea of parallel universes (a beloved sci-fi notion) gains legs, but in an adjusted way-- that it ranges vertically so to speak, rather than horizontally. (and of course it could always be both, or neither!)

3. Simply put-- hierarchy. We see hierarchy all across nature in the simple, direct sense of ‘there’s always something a little smaller, and always something a little larger.’ Or much smaller / larger. And that’s only in the dimension of physical size, of course.

Anyway, I’m quite sure we’ll never get to the bottom of this hypothesis before we asplode ourselves (as we’re already doing, thanks Billionaires!), but something about me really loves this idea.
