I'm flabbergasted!

I believe it was actually oog the neanderthatl who postulated, no light, no cave panting, leading to Einsteins theory that information was limited by light.
And of course in the future some people will choose another way of controlling information using something called "The Dark Side" of the force, negating this theory.
Well, sure, everybody knows that. But what if you send it through the Stargate two or three times first? ;-)
Einstein said a lot of things, but 'information' isn't in the index to his tract 'The Meaning of Relativity'. He also said that if chose to leave his second wife no force on earth could stop him.
"an optical fiber that had been laced with the element erbium"
So, if the fiber needed to be repaired or upgraded, that would be kinda like erban renewal?
Be careful of what you ask for on this forum. There are twisted people who (a) know how to use Photoshop, (b) have images of Helen Thomas on their computers, and (c) have waaay too much time on their hands.
Bump.
Well, that'll stun your beeber, which is very series!
Really nice article, PH. Every time I see a new physics breakthrough I'm painfully reminded of how specialized fields in science have become, because, to be quite honest, I really don't truly understand much of the physics they're talking about at all.
Wow, fascinating.
"As the pulse enters the material, a second pulse appears on the far end of the fiber and flows backward."
Sounds more like a reflection to me than a case of light "flowing backward." The only thing that seems odd about it when viewed in that way is the timing, i.e. that the second pulse appears immediately at the far end of the fiber, apparently just after the initial pulse enters the fiber.
So your first thought is that it can't be a reflection because the initial pulse has not yet gotten to the end of the fiber. However, they say that a portion of the light impulse is apparently flowing faster than its normal speed. I wonder if they just mean the normal speed thru the material, which might very well be less than the speed of light in a vaccuum. If so, then I'm not too suprised by the result. In fact, if that's the case, then it seems like they are making a mountain out of a mole hill.
There's a difference betwixt group velocity and phase veolcity.
I'm not a physicist, but this smells like BS to me.

How do they know it wasn't going backward in the first place?
Haven't these guys ever heard of a mirror? Next they'll be telling us that men and women are different.
It's all smoke and mirrors.
How does the leading edge of the wave of the pule of light contain the information on the whole wave? Is that not impossible by definition?
