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.
Mine blown 🤯
Idk I’ve thought about it and it’s like, if time is created by the passage into the event horizon and it’s an artifact of the n-dimension universe it can both imply that this n-dimension universe doesn’t have “time” as we know it and our experience of it is, again, artifactual. However, the “movement” of this universe toward a n-dimension black hole kind of implies time, at least in the sense that we understand it (physical state changes of matter. It was there, now it’s here! How’d it happen? Time!)
So… “Yes” but I would wager if my stoner theory holds gravity (pun intended) that whatever “time” exists in a parent n-dimension universe is not the same as time as we understand it? But maybe it is! Idk. Someone ask Neil degrasse Tyson why I’m wrong. And dont let him fool you that my model wouldn’t account for red and blue shifts as our little matter-islands shrink and “accelerate away” from one another. It do! 🙂
Also fun to ponder with my silly stoner model here is that… Well… There is a supermassive black hole at the center of most galaxies… Like it’s some sort of iterative and exponentiating recursive process? 😵💫
