An international team of astronomers have released the first direct image of a black hole, a long-distance snapshot of high-energy particles as they irreversibly plummet toward the black hole’s event horizon, the point where nothing—not even light—can escape. “We have taken the first picture of a black hole,” announces Eventread more

Two supermassive black holes are circlling each other–or they were, a million years ago, in a galaxy far away. In all probability, that galaxy is now being torn apart by the titanic equivalent of 100 million supernovas. So, did any civilizations experience the end of their worlds in that galaxy? If so, they would have been able to calculate the moment of their destruction down to the last second, an to have known about it for a very long time.

At the center of every galaxy – according to Einstein’s theory of general relativity – sits a light-sucking black hole that weighs the equivalent of millions or even billions of suns. Though normally quiescent, they can eat stars and gas for breakfast and belch quasars brighter than their own galaxy. read more

The unseen is always mysterious, but a British company has now developed the "un-seeable", a black material that is so dense it is totally incomprehensible to the human eye.

The new record-breaking "alien" fabric is 10,000 times thinner than a human hair, and absorbs all visual light bar an infinitesimal 0.035 per cent. Looking at it is apparently akin to staring into a black hole, a total void, as our eyes are unable to discern any shape or form and therefore register it as nothing at all.
