- mr_mechanics, on 10/12/2007, -0/+2This is nothing special. This is what NIST has been using for accurate time measurement for years, and
Wolfgang Ketterle (MIT) did this a long time ago (with bose-einstein condensates) and won the nobel prize (2001). They merely used lasers instead of the clover trap that Ketterle used. - saxmanlarry, on 10/12/2007, -0/+2I'm not quite sure why you give Ketterle the credit. Carl Wieman and his team from the University of Colorado at Boulder created a BEC in a lab months before the MIT group, and was also awarded the Nobel prize. He did use laser cooling as well as evaporative cooling.

- tynin, on 10/12/2007, -0/+2I know I saw a made for kids science movie clip & website at least a year or 2 ago explaining this exact process, but I cannot recall the name. in anycase, it is very interesting what atoms do under these conditions when they are super cooled.
- scott1, on 10/12/2007, -1/+3When I first read this I thought it said lasers used to control alram clock.
I need go to sleep. - tidejwe, on 10/12/2007, -0/+1Personally, I wonder if this could be used to trap and control anti-matter long enough to push it toward a black hole, at which point the black hole pulls it into itself and releases the anti-matter. When this anti-matter makes contact with the black hole (normal matter), it causes the whole thing to explode. Could you imagine an exploding black-hole? That'd be AMAZING! At least assuming it was a blackhole far, far away from our galaxy...

- tylerni7, on 10/12/2007, -0/+1I usually don't care when stuff is old, but c'mon... this is quite a few /years/ old.
- everfalling, on 10/12/2007, -0/+1two words: laser pong
- alevel27mage, on 10/12/2007, -0/+1My Feshman Year science teacher taught us about this...
He said that someone once asked Einstein what would happen if atoms next to eachother and similar in structure were stopped completely. Einstein said that they would come together and form a sort of "super atom". Then, I believe in 2002 or 2003, someone did the experiment. This is old news, but still cool. - illt, on 10/12/2007, -0/+0don't quantum computers use the same principle? using lasers to measure, trap and change the spin of electrons? or something.
- MrCrushington, on 10/12/2007, -1/+1This, ladies and gents, is how you make a jaded man chuckle.
