Black hole cosmology suggests that the Milky Way and every other observable galaxy in our universe is contained within a black hole that formed in another, much larger, universe.

The theory challenges many fundamental models of the cosmos, including the idea that the Big Bang was the beginning of the universe.

It also provides the possibility that black holes within our own universe may be the boundaries to other universes, opening up a potential scenario for a multiverse.

Ok yea that makes sense because we’re in hell

So it might be turtles all the way down?

Sooooo the expanse was right?

I'm mostly curious how higher dimensioal space could explain (perceived) expansion. Like: maybe we live in a 3d bubble embedded in an n-d space which keeps on collapsing, pouring more and more energy into our "universe"...

I’ve always believed that our entire universe is the inside of a gravastar in a 4D-universe. Our universe is the false vacuum inside it, permanently in superposition. We’re just one of the infinite potential states the wave function of the Bose-Einstein condensate inside could collapse into.

Oh, and gravity as a force would be the result of the 4D gravastar’s centrifugal force as it rotates on 2-axis, and that would be why we can’t figure it out.

At least that’s what I’ve always imagined reality. (Also known as my rambling brain doing its best in the moments between wakefulness and sleep)

Edit: tbh 5D/3-axis makes more sense

You might like this video by PBS Spacetime. I'm not sure how this relates to your centrifugal force idea, but we do actually know a few things about "what gravity is" that are really interesting.

Oh, I’ve seen this before! Although my interpretation is purely spatial and lacks any temporal component aside from the act of rotation itself. So it’s still applicable.

But if this leaves anyone in a philosophical mood, I leave this video on a comic book villain that unpacks into a metaphysical wonderment.

That why our timeline seems to keep radically changing?
