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.'"

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 /.
