Celestial body of the week: the black hole by Daniel

Black holes are places where gravity has become so strong that it overpowers all other forces in the Universe. Once inside, nothing can escape a black hole's gravity — not even light.For a very large black hole the tidal forces are not really noticeable until you get within about 600,000 kilometers of the center. No one will ever know what goes on inside a black hole, since no light or any other radiation can escape. I choose the black hole because its one of the strongest things in the universe
The nearest black hole is many light years away, so we don't have to worry about threats to the Earth. This is as close as you'll ever get to one. So come explore!
