You know that black holes eat everything, including light. But did you know it also eats time? Follow me here! http://www.facebook.com/answerswithjoe http://www.twitter.com/joescottwriter http://www.everythingjoescott.tumblr.com =================== Black holes are fascinating because they remind us of how limited our perspective is in the universe. I mean, gravity so extreme it eats light? And where does it all go? I mean, it’s devouring whole stars, all that matter has to go somewhere. Some think that the black hole’s singularity punches through to another universe in another dimension, like a big bang. Maybe that’s where our universe came from. Every black hole could be spawning its own universe, full of its own black holes, which create their own universes into this infinite mandlebrot set of universes and black holes that never end. There’s far too much to discuss about black holes to fit into one video, so I’m going to focus on the part of black holes that I find the most fascinating - the way it messes with time. See, the extreme forces surrounding black holes don’t just eat light, it also eats time. This was one of the major plot points of the movie Interstellar, they landed on a planet that was close enough to a black hole that every hour they spent on the planet equaled 7 years on Earth. One of the coolest facts I’ve heard about black holes is that if you fell into one, and could survive your body being spaghettified into a solid stream of atoms, the last thing you would see would be the entire future of the universe unfold before your eyes. Because of the extreme time dilation, a matter of seconds to you would equal billions of years to the rest of the universe. So in a very real sense, black holes exist outside of the dimension of time. Even cooler is that one of the side effects of the atom smashing going on at the Large Hadron Collider is that the energy in their collisions is producing microscopic black holes. They’re smaller than atoms and evaporate immediately, so they won’t eat up the earth or anything. But this quality of black holes, existing outside of time, has some speculating they could be the key to creating an actual time machine.
