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 honestly appreciate that we don’t understand the universe. Theories keep evolving and that’s what science should look like. If we can’t question “established” scientific theories, we have abandoned the scientific method. Strong theories hold up. Like the theory of gravity, although even there I’m not convinced we have a complete understanding. Good answers are good, but who knows what we might be capable of if we keep pushing for more.
