LIGO measured a distortion one thousandth the width of a proton over its 4-kilometre arms, from two black holes merging 1.3 billion light years away. Einstein himself doubted the waves could ever be detected. The 2017 Nobel Prize went to Weiss, Barish and Thorne, and gravitational waves now serve as an astronomical instrument in their own right.
Evidence tier V3 is the import default for a result the curation records as settled in the published record. No formal proof or certificate is attached to this page yet.
Posed 1916, Albert Einstein. Closed 2015 detection, announced 2016, LIGO and Virgo.
