Physicists have reproduced a pattern resembling the cosmic
microwave background radiation in a laboratory simulation of the Big Bang,
using ultracold cesium atoms in a vacuum chamber at the University of Chicago.
“This is the first time an experiment like this has
simulated the evolution of structure in the early universe,” said Cheng Chin,
professor in physics. Chin and his associates reported their feat in the Aug. 1
edition of Science Express, and it will appear soon in the print edition of
Science.
