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.

Man, this is so cool!!

I like these observations and theories, despite them being the ramblings of very ignorant creatures (all of us as a species).

This said, we don't have evidence to suggest we aren't the most intelligent creatures to ever exist. It seems very, very unlikely... But, such is the rarity of life so far as we've observed.

So... These are lots of fun! If not for any other reason, than for the reason of humbling us all.

Why aren't we all spaghetti, then?

black holes all the way down?

[–] ABetterTomorrow@lemm.ee 4 points 2 weeks ago

The way things are going, more like we got tossed in an endless trash can. I don’t blame the Vulcans.

[–] Formfiller@lemmy.world 3 points 2 weeks ago

Ok yea that makes sense because we’re in hell

[–] MehBlah@lemmy.world 3 points 2 weeks ago

So it might be turtles all the way down?

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"...

Sooooo the expanse was right?

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.

[–] voodooattack@lemmy.world 1 points 2 weeks ago

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?
