Interesting sci-fi plot device but seems far-fetched, not gonna lie. To think that our highly stable universe is just compressed mass of another universe is a lot to take in. Does that black hole emit Hawking radiation as well and shouldnt our universe lose mass in result? And how exactly can our universe expand if the size of the black hole is fixed?

Well, at least it does make for interesting conversations. Someone will surely milk it for Youtube content.
