Alright. I think, perhaps, I might have a handle on this. Maybe. I read this article a few months ago, but if someone could explain it a little better I'd appreciate both your effort and candor.
The article itself- http://www.rochester.edu/news/show.php?id=2544
My question is, how accurate is this? Is it possible FTL as it purports, a circumvention of relative limitations, or merely another victim of sensationalist reporting?
Insofar as it's [the pulse] not being able to carry information, what exactly does 'information' mean in this context? The information describing this pulse as 'light' for instance, or that of a signal transmission, or...
A negative-speed pulse of light acts much the same way. As the pulse enters the material, a second pulse appears on the far end of the fiber and flows backward. The reversed pulse not only propagates backward, but it releases a forward pulse out the far end of the fiber. In this way, the pulse that enters the front of the fiber appears out the end almost instantly, apparently traveling faster than the regular speed of light. To use the TV analogy again—it's as if you walked by the shop window, saw your image stepping toward you from the opposite edge of the TV screen, and that TV image of you created a clone at that far edge, walking in the same direction as you, several paces ahead. -from the article
