A small black hole would probably glow very bright by itself, so it could be a useful energy source in orbit (for a while, until it crashes into Earth).

- dredmorbius 9y agoObjects in orbit don't suddenly stop being in orbit. There's no reason a black hole would de-orbit into Earth. And if it did, it would largely continue to orbit through the Earth, or what bits of it remained following passage. That said, I don't suspect the approach would be particularly viable.
- MR4D 9y agoOdds are, it wouldn't crash "into" Earth. Rather, it would more likely crash "through" Earth. Difference seems subtle, until you find out that a black hole (one made by us at least) is soooo tiny that it would miss most of the atoms in the Earth, falling _between_ them. Apparently, you need lots of mass to make a black hole that is both sustainable and big enough to affect anything around it.
