A PBS Space Time episode asking whether our universe could sit inside a black hole. It covers what physicists think happens inside black holes and the arguments for and against this idea.
Pointed to as a clear treatment of the universe-in-a-black-hole idea whenever black hole cosmology comes up.

Your first link and one of the videos there ( this video ) was a huge relief and interesting dive into the q - thanks again for sending it.
PBS Spacetime covered this topic: this video Basically, with our current understanding, the only thing that makes the big bang and black holes seem connected is that they're both singularities. But, there's no explanatory value associated with the idea of the universe being the inside of a black hole, and thus there's no way to attempt to test it.
