I recently learned about delta-V as a concept. Flying directly into the sun, for example, is basically not possible for a spacecraft with today’s technology, without dozens of gravity boosts. You need to basically undo the speed of your initial orbit, which for something in orbit around a star is huge! A black hole would be even more difficult and require more Delta-V to fly into, if you’re in any sort of orbit. So you should definitely expect tons of stuff in orbit around them!
