(Inside Science) -- The 2017 Nobel Prize in Physics was awarded to three American physicists "for decisive contributions to the LIGO detector and the observation of gravitational waves."
The prize goes jointly to Barry C. Barish and Kip S. Thorne of Caltech in Pasadena, and Rainer Weiss of MIT, in Cambridge. The three recipients were responsible for theories and experimental techniques that led to the detection of gravitational waves in 2015.

What are gravitational waves?
Gravitational waves are ripples through space-time sent out by gravitational interactions between objects. On September 14, 2015, scientists detected gravitational waves for the first time. The signal originating from a pair of merging black holes was detected by the LIGO Scientific Collaboration, which has detectors in the state of Louisiana and Washington. The signal was eventually confirmed and the official announcement was made on February 11, 2016.
