A Black Hole Doesn't Die -- It Does Something A Lot Weirder

Black holes are basically "game over, man," for anything that gets too close to them, but they aren't invincible. In fact, they're always in the process of self-destructing. We'll look at how they fizzle out, and see if we can help them do it faster. The Event Horizon Realistically speaking, you are dead as soon as you get anywhere near a black hole. You'll be snapped like a rubber band by the differences in the gravitational pull on your top and bottom half, or you'll be fried by radiation (more on that later). No one in the foreseeable future (even if we try to foresee multiple millennia into the future) will get close to a black hole. Pass the event horizon, however, and you don't even have an unforeseeable future. Once material gets beyond the event horizon, it's being pulled into the black hole with such force that it doesn't escape. Not even light gets out. Once something has gone beyond the event horizon, it no longer really "counts" as part of the universe anymore. The event horizon is the scariest part of the black hole. It's also the reason that every black hole dies. In the world of quantum mechanics, the universe has an ace up its sleeve in what's come to be known as Hawking radiation. Particles and Antiparticles That Pop Up From Nothing For something that contains so much emptiness, the universe is surprisingly full. Black holes are not holes. They're giant bundles of extremely dense matter. Even stretches of empty space aren't quite the nothingness they appear to be. Particles appear and disappear inside of them all the time.
