Black holes are one of nature's great big mysteries! It is a region of spacetime in the universe where gravity is so strong that no particles can escape from it. There are many theories about how black holes are formed, but the most accurate one is that a sufficiently compact mass can deform space time to form a black hole. It's equal parts cool, equal parts frightening, and oh, so interesting. Let's see how much you know!
