This was a little strange to read."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."
Can it really be done? Make light go backwards?
Interesting to think about.

That it very interesting, but now my head hurts.
Mr Wadd, I won't pretend I can think about it for long, either.
*wry grin*
Yes have to admit that was confusing but cool.
