This woman slows down light to the speed of a bicycle (15 miles per hour) using an Bose-Einstein Bridge or whatever it is called. My speaker is busted so I cannot hear the narration to the video so if anyone could explain to me how the hell that works I would be appreciative. I know the substance is cooled down to basically absolute zero. And I know there should be no movement at that temperature. I don't know why the light would continue to exist but go slowly if there is such a gradient of energy.
Anyway, here is the video: http://www.nature.com/nature/videoarchive/trickofthelight/index.html
It is pretty freaking amazing. The temperature was taken down to 1 degree above absolute zero. I guess that explains why light still moved. The video mentioned that they were able to stop light in one position and then start it again in another location. Interesting.
Cool link, thanks for sharing 
Actually she said that the Bose-Einstein condensates were at a couple of billionths of a degree above absolute zero. Brrrr.
But from the way she was explaining it it wasn't because the light itself was cooled so much, but it was a result of the way the atoms in the condensate acted in 'lockstep' that caused the light to slow down, and to create a matter copy of itself to be transmitted to the second concentrate. But then, I'm not a physicist by any means, so I may not be understanding it correctly. A part of the definiton of cool, methinks... 
Have to get me one of those BECS built soon too.
Great stuff and shows that optical memory devices (that store holograms of the scene) won't be too far down the road. 
Yeah, this is totally cool. It really is a bit like time travel since the beam actually transfers from one position to another without traveling the distance. I have absolutely no idea how this works, but the video speaks of quantum mechanics and a weight of the wavelengths.
You should really get your speakers fixed so you can explain this video to us, it would make an amazing camera flash. (can you say permanently blinded?)
Absolute zero is darn cold, i think it's about -273C ... brrr
Absolute zero is really cold (I thought freezing was cold... brr!) but imagine how much hotter it can get than cold. For example absolute zero is as low as a temperature can go. Going up the scale, though, there seem to be no limits as to how hot something can get.
Would it be possible to speed up light by heating molecules? (not faster than in a vacuum, but faster than in normal room temperature)
