A Light Delay




A Light Delay

 Researchers stored yellow light for more than a second, by means of an imprint left in some of the atoms (dark blue) in a cloud of ultracold sodium atoms (gray). The beam that emerges (bottom) has the same properties but is weaker than the original beam (
Scientists from Harvard University found out how someone can keep light. A women called Lene Hau, a physicist, knew how to keep light for 1.5 seconds. What she wants to find out is like the game when a person whispers something to another person's ear and the other person has to whisper the same thing to the last person and the last person has to say the thing that whispered the first person. So the light is like the first person whispering it to the BEC (The BEC-Bose-Einstein condensate- is the fifth type of Matter that you can only find in coldest place ever. When the strangest known materials are put in the temperate of 0 degrees all of the atoms collapse into one tiny blob, that's called the BEC).
