There is also a theory that states that black holes, since they are singularities - are infact their own universe. It’s also not entirely unrealistic to apply that to our universe being in a black hole itself.
We know the observable universe has an age. In fact, we know there’s a limit to what we can see. We can locate galaxies 32 billion light-years away, but the redshift of its spectra confirms it is still about as old as the universe. Theoretically, just like an object falling in a black hole stretches forever, our expanding universe is the exact same phenomenon. There exist no spacetime paths that allow anything to escape our universe.

Black holes are not holes, they are hyperbolic non-euclidean space? Possibly
