This was posted a week ago and discussed ad nauseum. This is nothing new. Physicist says the group velocity remains sub light while the phase velocity is faster than light. My opinion is that they are setting up a large number of waves in a bounded wave guide such that the interference pattern of the waves make it seem like a single pulse is traveling at above light speeds, but what they are really looking at is a summation of sub light waves where the superposition of said waves only give an appearance of above light speed.

Yeah, um...what you said.

Sorry. I didn't search deeply enough. Please go HERE for that posting.

Or as Asimov once put it, things that move faster than light aren't really "things".

The real news is that they did it so inexpensively.

[Barry Goldwater]

They are merely changing the standing wave pattern on a series of transmission lines of different impedances. If you take into account the time it takes to set up the standing wave pattern, it is actually slower than the free space speed of light. Once the standing wave pattern is established, the resultant waveform can exceed c.

I agree. No way are they doing anything faster than c.
