The cosmic microwave temperature fluctuations from the 5-year WMAP data seen over the full sky. The average temperature is 2.725 Kelvin (degrees above absolute zero; equivalent to -270 C or -455 F), and the colors represent the tiny temperature fluctuations, as in a weather map. Red regions are warmer and blue regions are colder by about 0.0002 degrees. (Credit: NASA / WMAP Science Team)From The Science Daily:
ScienceDaily (May 4, 2009) — What happened in the first trillionth of a trillionth of a trillionth of a second after the Big Bang?
Super-sensitive microwave detectors, built at the National Institute of Standards and Technology (NIST), may soon help scientists find out.
The new sensors, described May 2 at the American Physical Society (APS) meeting in Denver, were made for a potentially ground-breaking experiment* by a collaboration involving NIST, Princeton University, the University of Colorado at Boulder, and the University of Chicago.
