I don’t think they know anything about the laws of physics inside black holes. Could our universe be a black hole? I was reading something about that a few weeks ago and I thought the best argument against it was that not only do we observe our universe expanding, we see it expanding faster and faster in time.
It doesn’t seem like we could possibly observe that situation if we were inside a black hole where presumably everything, including space, is rushing inward toward the center.
Squishes them to nothingness?
Always fun to look at the enormity and strangeness of our universe.
Thanks for posting.
