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 have always wondered about this and it's always been the question I would want to ask neil degrasse tyson about if I ever met him... I never realized there was a term for it or even other people believed it...

My other crazy theory is that we are always in a state of jumping between realities... As a state of self preservation... We exist in the reality where we keep living. With the possibility of realities being infinite and the possibility of a subset of those infinites being basically the same as the one you're in...

Who knows maybe it's just a reassuring way to be happy knowing that one day your actually going to die instead of all those times you have felt like you have almost died being truly a time you have died...

    As I understand it, the idea of Quantum Immortality is a bit more nuanced then that. It's not that you would be "jumping between realities". It's more-so that, as the reality where you are alive is the only one you can possibly be aware of, any reality where you would die simply wouldn't be seen by you. The splits where the potential to die exist would only be seen as "close calls" to the consciousness that is you. It's more so a resolution of logic than a cross-dimensional mind swap. A pop-culture example of this is sort of seen in

    Movie nameThe Prestige.

    Extra Major plot spoilerQuick summary - in the movie, Hugh Jackman's character gets access to a machine that instantly duplicates him, which he uses for his magic shows. To resolve the "small" issue of there being an ever multiplying amount of him, he has a mechanism to immediately drown the version of him on stage when they disappear as the other version reveals himself elsewhere in the theater. At one point, he talks about how he was always terrified that he would be the one being drowned. There's a few interesting things about this particular line, the most pertinent one being that he is never the version that gets drowned, evident from the fact he is talking about it. Obviously this is just fiction, but I think it's a good illustration of the concept. There are also a lot of details left nebulous, possible details of which could suggest Destructive Teleportation instead.

    Our consciousness continuously transferring between realities to stay alive is kinda crazy ngl

    What's the big question you've always wondered about though? It's not clear from your comment

    If the whole observable galaxy is inside a black hole...

    Black holes get bigger and expand as does our observable universe... I always wondered if the two were connected...

    But from reading everything in this post it seems like the theory doesn't hold up... But also who knows...

    I like my other theory better anyways.
