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.

I've kinda thought that were some n-dimension universe getting sucked into an n-dimension black hole, and what happens as that universe crosses the event horizon is the big bang, the arrow of time. And all of the matter and forces that have them appearing to interact is just some beautiful n-dimension spaghettification.

The universe isn't expanding; all mafter within it is shrinking, being crushed. all matter appears to be accelerating further and further away because, well, it is. From our perspective.

Think of our whole universe as the most epic allegory of the cave possible.

I'll go back to ripping my bong now.
