ASTROPHYSICS:
Microwave Hump Reveals Flat Universe
James Glanz
PARIS--In measurements of the cosmic microwave background, a faint microwave glow on the sky that is the afterglow of the big bang, astrophysicists are seeing a sign that the cosmos contains the full complement of matter and energy that theorists have long postulated. The observations, made by two microwave telescopes at the South Pole and announced here in mid-December at the Texas Symposium on Relativistic Astrophysics and Cosmology, confirm a key prediction of the best-accepted theory of how the big bang got started, called inflation.
