Physics is so relaxing to watch, :D
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 Trapezium Cluster, is a tightly packed cluster of stars in the heart of the Orion Nebula, in the constellation of Orion. It was discovered by Galileo Galilei in 1617.This particular image highlights the ridge created at the “Bright Bar” of the Orion Nebula, as the intense UV-light and strong winds from the hot Trapezium stars eat their way into the surrounding molecular cloud.
