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 saw some science stuff on YouTube the other day that explained that the expansion of the universe seems to have started before the big bang. Also that the expansion is what caused particles to come into existence from nothing and thus creating the big bang.

Found it: https://www.youtube.com/watch?v=OHdUFPAK7f0

Anyway, you're right that whatever was before or outside the universe is irrelevant to us. However, if we can get closer to understanding as much of the process as possible, it might still pave the way for something that we can use today.
