It marks the first time that scientists have been able to observe a cosmic event with both light waves -- the basis of traditional astronomy -- and gravitational waves, the ripples in space-time predicted a century ago by Albert Einstein’s general theory of relativity.</span></p> Mon, 16 Oct 2017 14:04:16 +0000 webfull 131941 at /channels /channels/channels/news/nobel-prize-physics-goes-gravitational-wave-scientists-271343 <p>The Nobel Prize in Physics 2017 was divided, one half awarded to Rainer Weiss, the other half jointly to Barry C.
