Submission + - Liquid Crystals Can Slow Down the Speed of Light a Billionfold (vice.com)

Daniel_Stuckey writes: Even in Elon Musk's Hyperloop, you'd only be going a fraction of the speed of light. But if we played with physics a bit, as researchers at China's Xiamen University and France's Universite de Nice-Sophia Antipolis have done, essentially any movement could be faster than the speed of light. Using a new technique, they've managed to slow the speed of light to less than one billionth of its speed in a vacuum. Slowing the speed of light, of course, is not going to get us to other galaxies any faster. It's not going to help with space travel at all. But slowing the speed of light does have some practical applications here on Earth. The idea of "slow light" is not a new one: Researchers at Harvard slowed light to a speed of about 17 meters per second in 1999.
