By sending light through bose-eistein condensate ( hope I spelled it right, and im going to use BEC instead from now own) the light slows down. Do the particles have a traffic jam at the BEC or do they move closer to gether. normal light BEC slow light close together | | | | | | | ||||||||||||| like this or like this | | | | | | | ||||| | | | | | | normal light BEC slow light with traffic jam I base this off of cars on the interstate. If one was to slow down there would be a trafic jam and the cars would all be close together. Also, if the car stays slow for to long, the trafficjam backs up farther. If given long enough, it will back up to where the interstate begins.(This is based on a one lane interstate. Instead of cars, use photons. Will this happen or is there some fact im missing?? ??
