Prof. Emeritus Rainer Weiss, a “renowned experimental physicist” who was “integral in confirming the existence of tiny ripples in spacetime called ‘gravitational waves,’” has died, reports Robert Lea for Space.com. “Remarkably, in confirming the existence of gravitational waves, Weiss both proved Einstein right and wrong at the same time,” writes Lea. “Einstein had been convinced that these ripples in spacetime were so faint that no apparatus on Earth could ever be sensitive enough to detect them, showing just how revolutionary LIGO was.”
