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.

The speed of light may be the key to our getting off this planet. NASA physicist Harold G. White and his team are trying to determine whether faster-than-light travel–a "Star Trek"-type warp drive–might someday be possible (NOTE: Subscribers can still listen to this show). In the July 23rd edition of the New York Times, Danny Hakim quotes White as saying, "Space has been expanding since the Big Bang 13.7 billion years ago, and we know that when you look at some of the cosmology models, there were early periods of the universe where there was explosive inflation, where two points would’ve gone receding away from each other at very rapid speeds.

Ever heard a star scream? Astrophysicists have detected the oscillating signal that heralds the last gasps of a star being sucked up by a previously dormant supermassive black hole.

The "screams," scientifically known as "quasiperiodic oscillations," occurred steadily every 200 seconds, but occasionally disappeared. Such signals have often been detected at smaller black holes and they’re believed to emanate from material about to be sucked in.

A black hole is a region in space where the pull of gravity is so strong that nothing, not even light, can escape. Black holes billions of times bigger sive than our sun may be at the heart of most galaxies, and astronomers have now discovered one in the center of a galaxy 50 million light years away that contains the mass of 6 billion suns–and measured its radius.
