This seems like an interesting concept for a sci-fi story: "1 Million Habitable Planets Could (Theoretically) Orbit a Black Hole. Here's How"
@cstanhope Apart from gravitational ripples tearing everything apart, gamma radiation would be brutal. It's not even theoretically a good idea to live on a planet near a black hole.
It would have to be an orbit very, very distant from a tiny black hole.
I suppose microbes and some basic lifeforms could conceivably exist on such a planet provided there's enough water, but anything larger than a few cells would find it extremely hard to live there no matter chemical and geological conditions.
