Read original comment ↗PBS Spacetime covered this topic: [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.
