Black holes spit up the matter within them
Supermassive black holes are constantly spewing out enormous spitballs made up of planets and stars. At first, we were told that there were massive planet-eating creatures living in our solar system. Then science reassures us that they aren’t going around actively feeding on planets and stars; they consume whatever comes towards them. We then worry that one day we might be on its path, but luckily science informs us that we’re nowhere near its course. Does this make you feel better?
These heavenly bodies regularly eject a large portion of what they consume. However, there is no telling where these spitballs will land. So we could very well have one on our way. But how does a black hole that never lets anything escape suddenly let things out randomly? We know they can when they emit radiation, but those aren’t so much of a danger to Earth. These spitballs are actually particles that escape the event horizon. When this happens, several objects can split and remain orbiting within the outer layer of the black hole. They can be ejected and sent flying in various directions at high speed over time.
