Electrical Pulses Break Light Speed Record

Posted by chrisd on Thursday January 24, 2002 @05:51PM from the canadians-show-us-the-way-again dept.

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.'"

FTL - information backwards in time by kippy · 2002-01-25 02:31 · Score: 0, Offtopic

I'm not a physicist or anything but doesn't faster than light communication allow for information to be sent backwards in time?

Also, will this allow me in any way to go to my parents' home town and get into a chance with the local bully, resulting with a dump truck of manure being dumped on him?
