Black Hole Birth Detected this Morning

An anonymous reader writes "SPACE.com is reporting on the first optical afterglow ever detected from a short-duration (milliseconds) Gamma-Ray Burst. The GRB signals the birth of a black hole resulting from a merger between two neutron stars. Theory had predicted the whole thing, which was all spotted this morning by NASA's Swift satellite and ground-based observatories, thanks to an automated email system that notifies astronomers worldwide."

    The Gamma ray burst was determined to emitted from a very large cigarette lighter igniting a very, very large cigarette. SETI recorded the first successfully detected extraterrestrial broadcast of a message, which they believe was "Was it good for you, too?" Bachelor and bachelorette scientists around the world are extremely puzzeled and have few clues as to what it all means.

    This is how science works, people come up with testable ideas which are proven right or wrong. No-one is arguing that super-dense, intrinsically dark objects don't exist, we have plenty of evidence that they do. Infinitely dense singularities, well, maybe not - if they exist as we predict they're inside an event horizon and therefore unobservable so actually directly verifying their existance is always going to be impossible... all we can do is come up with odd ideas like dark energy stars which might bounce matter out and see if we can observe that happening.
