Gravity waves. (Insight).(Brief Article)

GRAVITY WAVES: After a star goes supernova, it doesn't just disappear. It collapses into an incredibly dense neutron star--just a dozen or so miles in diameter--that can spin wildly at speeds of up to 1000 revolutions per second. Scientists have predicted that the energy created by this phenomenon radiates outwarding in giant gravity waves. But such waves have never been detected, only hypothesized in Einstein's general theory of relativity. A world-wide network of gravity-wave detectors has recently begun to search for these elusive waves. And to help ...
