I'd like to learn more about astronomy. What are the most important facts about black holes?

1. Black holes are regions of space-time with such strong gravity that even light cannot escape from them.
2. The gravitational pull of a black hole is so powerful that it can bend and warp spacetime, creating an event horizon.
3. Black holes have a mass limit called the Schwarzschild Radius which is the radius at which the escape velocity equals the speed of light.
4. A black hole's spin affects its appearance and behavior.
5. Black holes emit radiation due to quantum effects known as Hawking Radiation.
6. Black holes can be classified into three categories based on their size: stellar-mass black holes (less than 3 solar masses), intermediate-mass black holes (between 3 and 100 solar masses), and supermassive black holes (more than 100 solar masses).
