Celestial body of the week: the black hole


By:Daniel Gonzalez


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 becouse its one of the strongests things in the universe
The nearest black hole is many lightyears 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!
