Black holes are known to have such a strong gravitational pull that objects can't escape from it. Einstein's theory predicted that an object with a very compact mass could affect space-time and create a black hole. ]]> 2016-11-14 18:03:06 UTC https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137479173 fitzgky2 https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137480948 2016-11-14 18:06:41 UTC https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137480948 fitzgky2 https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137481936 2016-11-14 18:08:44 UTC https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137481936 fitzgky2 https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137482960 A common question when discussing the existence of black holes is whether or not we'll ever be able to see one in person...]]> 2016-11-14 18:10:30 UTC https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137482960 fitzgky2 https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137483911 2016-11-14 18:12:18 UTC https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137483911 fitzgky2 https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137485342 According to Charles Liu, an astrophysicist at the  American Museum of Natural History's Hayden Planetarium, "If you were to take a step into a black hole, your body would most closely resemble 'toothpaste being extruded out of the tube,'"]]> 2016-11-14 18:15:14 UTC https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137485342 fitzgky2 https://padlet.com/fitzgky2/mvghjhwmwl01/wish/137846857 Unfortunately, you have virtually no chance of survival once in contact with a black hole.

So the faster you move through space, the slower you move through time," he said. "Furthermore, as you fall, there are things that have been falling in front of you that have experienced an even greater 'time dilation' than you have. So if you're able to look forward toward the black hole, you see every object that has fallen into it in the past. And then if you look backwards, you'll be able to see everything that will ever fall into the black hole behind you.
