Light Stopper
A short video about an experiment by Lene Hau regarding the stopping of light. Date- Sept 2001. Source- http://www.news.harvard.edu/gazette/2007/02.08/99-hau.html More info- http://physicsworld.com/cws/article/print/20 'The ability to stop light in its tracks by passing it through a cloud of ultracold atoms could lead to new techniques for optical storage.'

L'uomo ha riuscito a fermare la luce!
@curiouswolves what? she was considered as a strong candidate, never won nobel prize
@Emamnuelguzman86 i thought she was a man.
@Emamnuelguzman86 Really?
did Einstein really believe stopping light was impossible or is that BS?can some one quote him
Interesting video showing the interaction between electromagnetic energy and it's reaction with matter. The equivelant of freezing an ocean wave instantly and thawing it out instantly.
this is a neat discovery. cause if you can slow light down and measure that and this will help us understand how to go faster then light
Lightsaber tech? bahaha
imagine if we could slow and or stop Gamma Rays.
She did win the Nobel prize.
What! she should get the novel price, or is that only for men?
Just saw this... so basically your taking the heat of an atom, freezing salt atoms, and stopping the light with the cooled atoms. Like trying to put out the fire of a fire with ice! But this fire ain't going out, it's just slowing down! Dang, it sure took alot of machines to do that!
fizzy: im not sure, but my answer would be no. i think this only works for very specific wavelengths, and only in one direction. but im not sure. if i would be correct, your "bottle" would only store the light of one specific wavelength that it gets from one specific direction. so your "bottle" would "look" into one specific direction, and tell you how much light of one specific color it gets. but thats enough to pump a load of digital data into it and get it back 1 second later...
so .. let me get this straight.. if I put "the cloud" in a "bottle" and put it in my room and keep it at it's (liquid) temperature for a second... and take it somewhere else (fast enough) I can see for a second the image of my room in that bottle ? (in theory)...
I just saw this on History Channel this evening. I had to look her up and this is her moment (thus far) in history (yet it happened in '01). This is totally a 'Star Trek' revelation but the real benefits will more quickly be known to Computing, storage and security thereof. Kurtilein: I'm not sure what your level of digestion is on this matter, but assuming it's not too advance check out "History" "The Universe" "Light Speed" for a bit more on it.
wow that explain alot of other mysterys for me, now let me go invent
too bad that she didnt explain how it works. but this doesnt violate general relativity. i already heared about some related experiments and got some explanations, basically methods like this make use of the wave-properties of light and slow down the group velocity of those waves, while the phase velocity stays the same. you can think of it as waves riding on the laser beam, the velocity of the beam stays the same but the waves on top of it can be caused to slow down.
