A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape. It's formed when a massive star collapses in on itself.

Some mind-blowing facts about black holes:

1. *Intense gravity*: Black holes have such strong gravity that they warp space and time around them.

2. *Types of black holes*: There are stellar black holes (formed from star collapse) and supermassive black holes (found at galaxy centers).

3. *Mysterious*: Black holes are still a topic of research, and scientists continue to uncover their secrets.
