This is actually a very interesting issue.

If you have never read about it, any black hole, no matter how small, in the earth’s gravity field will oscillate back & forth though the earth, gaining mass will each passage, eventually eating up all of it.

Generating one would mean the end of all life.

While I doubt it will happen, it is a sobering thought.

Not if the black hole has an electric charge. Then you can suspend it with an electrostatic field, and it can't eat anything. However, small black holes *evaporate* rather quickly... like a quick chemical reaction produces a rather nasty bang and other side effects, so would a constrained black hole evaporation. But if it gets "loose" then it will "eat".

Yeah, it is sobering. Sort of a Pac-Man.
