I love the idea. It’s one of our current physics hypotheses I hope is true, because it means the universe would be full of tiny things the size of a hydrogen atom with the mass of asteroids. “The devil’s glitter?” BTW they would not suck up planets and stuff like inaccurate sci-fi. One could be going real fast and fire right though the Earth and do little, maybe cause some seismic events, but we would never know unless we knew exactly what to look for. A tiny black hole would have a tiny event horizon. If you dropped one into a planet or star with a low enough velocity that it didn’t shoot out the other side it might do a lot of damage, then come to rest in the middle and slowly grow. I recall reading that one in Earth’s core would take possibly millions of years to do much since the radiation pressure caused by accretion around it would limit the rate of matter falling into it. Earth would eventually become an Earth mass black hole but it would not happen in any human lifetime, possibly not in the lifetime of the human race.
