Hawking Radiation

Black holes die in a fiery burst of energy, as shown on the left in the handy dandy animated GIF I found on the internet. Stephen Hawking came up with concept. He basically said that an object with such a great amount of energy must expel some of its stuff. He proposed that gamma rays escape from a black hole (they are invisible) at a very slow rate. But it's fast enough to let a black hole die after a long life.
