re: #6 Snarknado!
I’d like to think she meant our entire universe in the sense of everything near and dear to us (that is, the entire planet)… but somehow, I doubt it.
(No, I don’t know whether a “small” black hole would swallow the entire planet, it probably depends on the trajectories of both — let’s not test it.)
There’s a super massive black hole in the center of our galaxy, yet the galaxy, and us too, are still here.
Black holes don’t work the way most people seem to think they work.
