- <center style="background-image : url('http://i274.photobucket.com/albums/jj258/KUSHER6/Bground 8/whitewithglitterstarsbg.gif') ; background-repeat : repeat; background-position : top left ;"> Describing the study as a `scientific adventure and formidable challenge', Professor Leonhardt, of the University's School of Physics & Astronomy, said, "Creating optical analogues (simulations) of the event horizon has been an exciting adventure with many ups and downs, high hopes and deep disappointments, an adventure that seems destined to continue. So far, most of it is still theory, but we succeeded in the first small step of demonstrating in the laboratory the physics of horizons for light.

- It won't be so funny when it sucks their eyes out.

- A black hole simulated by lasers.

- From the page: "It is the first time that scientists have successfully simulated an event horizon using light. There is no danger however of the scientists being sucked into deep space by an intense pull of gravity, since the tabletop device only acts on light in optical fibres and is perfectly harmless. The St Andrews demonstration of the physics behind the event horizon, in which they measured the shifting of light, has been described as a `milestone'. The researchers accomplished the feat by firing laser light down an optical fibre - with different wavelengths of light moving at different speeds, creating a distortion which causes a wave of light to be trapped - effectively a black hole event horizon which cannot be escaped."

- From the page: "There is no danger however of the scientists being sucked into deep space by an intense pull of gravity, since the tabletop device only acts on light in optical fibres and is perfectly harmless." Considering that 1) The experiment is not in deep space, and 2) black holes don't "suck", I'm not terribly impressed.

- Fascinating idea, but why is the page polluted with outdated ads for pseudoscience?

- Black holes. Not as you might think. hehe

- From the page: ""It happens all the time in optical telecommunications where information is carried by light pulses which change the speed of light - whenever people communicate via fibre optics, using the internet or making long-distance phone calls, they create numerous artificial event horizons as a side effect without noticing it. The front end of each pulse generates a black-hole horizon, an area that light cannot leave, while the trailing end acts like a white-hole horizon, an area that light cannot enter," he said."
