| Member | Bizarre. "The speed of light, as we've all heard, is a constant: 186,171 miles per second in a vacuum. But it is different in the real world, outside a vacuum; for instance, light not only bends but also slows ever so slightly when it passes through glass or water. Still, that's nothing compared with what happens when Hau shines a laser beam of light into a BEC: it's like hurling a baseball into a pillow. "First, we got the speed down to that of a bicycle," Hau says. "Now it's at a crawl, and we can actually stop it—keep light bottled up entirely inside the BEC, look at it, play with it and then release it when we're ready." |

![]() | Surely a contender for "Quote of the Year" ![]() Also the article mentioned the use of infra red beams to cool stuff down So that means We could soon have an infra red fridge to go with the old school microwave oven. |
