On the topic of black holes, there is a recent paper on black holes potentially converting mass into dark energy: https://iopscience.iop.org/article/10.1088/1475-7516/2024/10...

Is your crazy idea not effectively the oscillating universe theory proposed by Einstein?

I think once we finally get this all sorted out, future humans will find it hilarious that so many people were convinced that dark matter was real and particles we could not detect made up 80% of the universe.

Completely agree and feel the same way about dark energy.

The next thing you will tell us is the Aether is not real.

If that’s the case, why was it a bang instead of a slow leak?

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.

Completely agree and feel the same way about dark energy.

Dark energy is the force that counteracts the combined gravity of our enormous universe. It also keeps the electrons flowing around the nucleus, but not into it.

The universe started with a single Big Bang, but is maintained by an interrelated force continually applied that keeps allowing it to resist collapse, the resulting system allowing local minima such as Earth's sweet spot of smallish sun + gentle orbit.

It's almost like it was designed to be perfect, with nicely balancing counterforces, all set in a sea of brutal extrema, and all set to mathematically clockwork precision that is discoverable by intelligent inhabitants, whose bodies, themselves, operate under those same physical laws. Almost ;-)

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.

It’s almost like the ones that aren’t ideal for life don’t tend to have much life to notice that fact.

There is actually a theory that black holes create universes inside them, and that our universe could be underneath countless layers of black holes forming universes that form black holes ad infinitum.

There is a Kurzgestadt video[0] that discusses the theory in more detail. Granted, this is in the realm of science where we have no idea if this is remotely true, but that's part for the course when black holes are involved.
