c++

The speed of light was broken again by researchers at Universities in Germany and in the US. As reported on the Discovery channel website and at other places.

Technically I suppose what travelled faster than light was "information" but that still has to ultimately be an actual signal of some sort. Very odd but wonderful!

I only wonder what would happen if they lengthened the erbium laced fibre optic?

At some length does the amount of speed exceeding c slow down? Or does the transmission still occur in the same way? And then if it does not slow down, then how far could a cable be laid where the light is transmitted still above c?
