Electrical Pulses Break Light Speed Record

J'raxis writes "PhysicsWeb writes that 'Pulses that travel faster than light have been sent over a significant distance for the first time. Alain Haché and Louis Poirier of the University of Moncton in Canada transmitted the pulses through a 120-metre cable made from a coaxial 'photonic crystal.' Haché and Poirier emphasize that their experiment does not break any laws of physics. Although the group velocity exceeds the speed of light - an effect permitted by relativity -- each component of the pulse travels slower than light.'"

    Yes, relativity is like a willow tree, bending in the wind, not breaking, and it gets all those tiny little leaves all over your yard.

    In other words, WTF are you talking about???

    Although the group velocity exceeds the speed of light ... each component of the pulse travels slower than light.

    My team words just the opposite: Each individual working at breakneck speeds, but the group never gets there fast enough.

    Now if they only could stop posting to /.

    The phenomenon is called the "Crack Mod" effect. When a Slashdot moderator is subjected to the influence of a sufficiently high amount of crack, the laws of nature and even fundamental logic begin to break down and effects such as this can be witnessed.
