"Lene Hau has already shaken scientists' beliefs about the nature of things. Albert Einstein and just about every other physicist insisted that light travels 186,000 miles a second in free space, and that it can't be speeded-up or slowed down. But in 1998, Hau, for the first time in history, slowed light to 38 miles an hour, about the speed of rush-hour traffic.

Two years later, she brought light to a complete halt in a cloud of ultracold atoms. Next, she restarted the stalled light without changing any of its characteristics, and sent it on its way. These highly successful experiments brought her a tenured professorship at Harvard University and a $500,000 MacArthur Foundation award to spend as she pleased.

Now Mallinckrodt Professor of Physics and of Applied Physics, Hau has done it again. She and her team made a light pulse disappear from one cold cloud then retrieved it from another cloud nearby. In the process, light was converted into matter then back into light. For the first time in history, this gives science a way to control light with matter and vice versa."

Nice post Amana and thats one smart lady

Just out of interest.......
There is something in our local universe that slows light down to 2mm a sec. The inner core of the sun slows light to that level, light takes 100's of years to get to the surface of the sun before it then speeds upto the usual 186,000 miles per sec.

All of this will be for naught if they can't build me a Lightsaber...

yeah i had an idea of how to make a REAL lightsaber (it would not be able to retract though)

would you like to hear it?

well, it would need a lot of power, take alot of time to work the exact science out.. and a few more years of research, but it should be good after that

take a class 4 or 5 laser, be able to fit it into a handle size + battery. get a diamond shaft about 3 to 4 feet long and put it on the end.

the important part of the diamond is that at the end is a silvered material that can keep the laser bouncing back and forth through the whole edge.

another important part that makes this be able to cut through anything is the embedded nano-filiments (in the diamond substrate) that absorb the laser light and heat up. the effect would be an egde that is very hard to begin with (being diamond) and heated enough to vaporize any thing within a certain diameter.

the only thing i am having trouble with is finding a shield for the user so the extreme heat does not kill him too.

i was thinking this could be used on a vehicle of some sort to get rid of debris and for mining and milling of rock (carving?)

just something i think could happen in my life time
