SPACE.com -- Astronomers Detect First Split-Second of the Universe: "Scientists announced today new evidence supporting the theory that the infant universe expanded from subatomic to astronomical size in a fraction of a second after its birth.
The finding is based on new results from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) satellite, launched in 2001 to measure the temperature of radiant heat left over from the Big Bang, which is the theoretical beginning to the universe."
