What are some amazing facts about black hole?
I've heard of that before. What else can you tell me?
Well, there are actually three types of black holes: stellar, intermediate, and supermassive. Stellar black holes are the smallest, and they form when a star collapses. Intermediate black holes are slightly larger and their formation is still a bit of a mystery. Supermassive black holes are the largest and are thought to exist at the center of most galaxies, including our own Milky Way.
