Black Holes


Really Dumb



Black Holes
Black holes are mysterious, super-dense areas in space that are so powerful that not even light can escape from them. You can’t see them, but scientists can tell they’re there by the way they affect other things nearby. Think of a black hole like a giant cookie jar. The cookie jar is so big and so full of cookies that when you try to take one out, it sucks the cookie back in and won’t let it go. That’s what happens to light when it gets near a black hole—the gravity is so strong that the light can’t escape. The size of a black hole can vary a lot, but the biggest can be as big as 20 times the size of our sun. That’s really big! A fun fact about black holes is that scientists believe that the biggest black holes were formed when two smaller ones collided.
