Astronomers have discovered what a black hole really is! A mass so dense that not even light can escape! This way astronomers now know how black holes form precisely under specific conditions what there capabilities are, and what we need to do if one ever decides to visit the solar system."Because no other information can escape from a black hole, knowing its mass, spin, and electrical charge gives a complete description of it," said Mark Reid, of the Harvard-Smithsonian Center for Astrophysics (CfA). "The charge of this black hole is nearly zero, so measuring its mass and spin make our description complete," he added. This means that all the dimensions and qualities of a black hole has been measured and this is all we can ever know about it.

This article connect to our previous unit about density because a black hole is so dense that nothing can get out of it that we know. This could be good for the society because we know what one of the deadliest thing in the universe is so we might have a chance of surviving. I chose this article because black holes interest me the most in the unit of space. This article came from a reliable source because science daily always cites it's resource and the people who talk about the discovery are professors. I agree with the scientists theory that we learnt all we can about black holes because we can't send any satellites to inspect black hoes because we won't receive any signal.
