With James S. Bullock, Sean Carroll, Moogega Cooper, Katie Freese. I plan to study general relativity in more detail in the future if I ever have the time to do it and I suggest you do the same if you want to … As the black holes have gravity so incredible that even the light fails to escape, time for an outside observer stops at the event horizon. Explore how black holes aided the evolution of a universe suitable for life, discover how we can see into a black hole's past, and find out how we might one day image the supermassive black hole at the center of our own galaxy! You’d never see an object falling into the black hole. You then use measurements of the movement of objects around a suspected black hole to calculate the black hole’s mass. The math with regards to black holes, which is part of general relativity, only works on the outside of the event horizon of black holes. Of course, it’s also a little misleading. Black holes are not the violent monsters people think they are, and new discoveries reveal that they might have been essential to creating stars, giving light, and building the universe itself.
They questioned what the existence of black holes means for other physics theories. Black holes aren’t really holes at all, but instead they’re areas of incredibly strong gravity resulting from (we think) a singularity. The math breaks down at the event horizon and below. This still doesn’t answer the fundamental question: how do black holes work?
But bit by bit, astronomers tallied up evidence for black holes’ existence. Black holes were once thought to be only a mathematical curiosity. It will completely freeze at the event horizon and will slowly disappear. If black holes draw you in, be sure to check out our FREE ebook on black holes. They were bizarre beasts that squashed gobs of matter into infinitely dense abysses. Black holes are possibly the most mysterious objects in the universe, and their name doesn’t really help their reputation.

I cannot explain the details on how the math of general relativity works outside of black holes. Black holes will always move you closer to the centre by approximately 7,000 light-years (+/- 1,000 ly) unless they are part of the hyper black holes which can be used to travel insane distances of over 300,000 light-years towards it. Black holes consistently move you about 1,500 light years closer to the center.
Many black holes have objects around them, and by looking at the behaviour of the objects you can detect the presence of a black hole.
