Laser Light Re-creates 'Black Holes' in the Lab

yodasz writes "The New Scientist reports that a team of researchers from the UK were able to recreate a black hole's event horizon in the lab by firing a laser pulse down an optical fibre. The team's observations confirm predictions made by cosmologists and now they are trying to prove Hawking's hypothesis of escaping particles, dubbed Hawking radiation. 'The first pulse distorts the optical properties of the fibre simply by traveling through it. This distortion forces the speedy probe wave to slow down dramatically when it catches up with the slower pulse and tries to move through it. In fact, the probe wave becomes trapped and can never overtake the pulse's leading edge, which effectively becomes a black hole event horizon, beyond which light cannot escape.'"

    As long as they didn't create a real black hole.

    That would suck.

    That sounds safe, to reproduce the effects of the point at which all matter collapses into a virtual singularity. Where were they testing this again? Somewhere on Earth? Alrighty then... Taxi!

    Wikipedia? What? You know that's not a reliable source of information. So I looked it up in the uncyclopedia:

    A Black hole is an impossible object which makes the Universe work. It has the useful property of being "undetectable". It's like when your spouse comes home with a dent in the car, and blames it on an invisible black mass; the dent is proof of the black mass, but you can't, and never will be able to see it with CCTV cameras, but you know it's there. "Dark matter" is an equally undetectable force that causes cars to defy gravity, and hit invisible black holes. Astronomers will tell you that lots of them have spouses with dents in their cars, and can explain this is very technical terms, so you won't be able to understand why it's not possible.

  9. How the universe works by spun · · Score: 5, Funny

    God made the universe 6,000 years ago. If you do not worship him and subjugate yourself to his will, he will torture you forever. He just put in things like dinosaur bones and black holes to mess with your head, to get you to disbelieve in him, so that he can torture you forever without feeling guilty about it.

    He's kinda messed up because he was alone for like, eternity, until he made up some friends in his head, but he's incapable of imagining anything that is actually his peer, so he secretly hates us all for not providing the companionship he needs. That is how the universe works.
