How do we know a black hole can’t establish some kind of equilibrium as it absorbs the matter around it? (Maybe only briefly, but enough for observers to see that this one isn’t going away.) There could be time for a warning, for whatever good it would do.

I think there was a movie, or at least a sci fi book about that.

In any case, for that scenario, the black hole is smaller than atom in the beginning, and adding quarks and electrons probably won’t happen too fast initially, but the sucker does have mass and is in the earth’s gravity well, so the chances are that it will just fall through the earths center gobbling up atoms, and I believe the calculations would give it about 30 minutes to do that. Then when emerging on the other side, due to the earth’s rotation etc it would likely just zip off to space and starve to death soon.

Anyway that is what I’ll put in my book when I write it, and I’ll ignore that cosmic rays that hit us every millisecond have higher energies than the LHC and all that implies.
