Catching gravity waves from the big bang
U. CHICAGO (US)—A tiny fraction of a second following the big bang, the universe allegedly experienced remarkable growth, with space expanding faster than the speed of light. A University of Chicago team is hoping to prove the theory by detecting remnants of radiation emitted at that early moment, when gravity waves rippled through the very fabric of space-time itself. (more…)
