 All right, so here's another thing we can worry about. Apparently black holes can just become dislodged from their location in space and just float away. That's the next thing. I mean, I couldn't say I would object that much if they told us that a black hole was floating towards Earth. I think our reaction, first of all, would be, well, of course it is. Of course a black hole is coming. Put us out of our misery. So there's a missing black hole.
