fafalone Posted September 16, 2002 Share Posted September 16, 2002 According to the latest research published in Applied Physical Letters, MTSU scientists used a setup that cost about $500 to set up a system that brteaks the speed of light (group velocity, not individual particles).

blike Posted September 16, 2002 Share Posted September 16, 2002 What is the difference between group velocity and individual velocity? Link to comment Share on other sites More sharing options...
fafalone Posted September 16, 2002 Author Share Posted September 16, 2002 The signal gets there in a speed greater greater than c (and at a time before it left), but not of the individual particles that make up the message are ever going faster than c. Weird stuff. For more info, search google for 'superluminal propagation' Link to comment Share on other sites More sharing options...
