What it means
Einstein predicted these ripples in 1916 and doubted anyone could ever measure one. The stretch reaching Earth from a collision a billion light years away changes a four kilometer measuring arm by a fraction of the width of a proton. Detecting that took decades of engineering, a pair of instruments far apart so that local shaking could be ruled out, and the first confirmed signal arrived in 2015, a century after the paper.
The claim comes from LIGO Scientific Collaboration.
