Three scientists Rainer Weiss, Barry C. Barish, and Kip S. Thorne share their Nobel Prize for Physics for their discovery of gravitational waves

The Swedish Royal Academy of Sciences said the 1.1 million USD prize will go half to Weiss and half to Barish and Thorne.

LIGO is a 620-million-USD gravitational-wave observatory station that helps scientists observe two black holes collide, which creates gravitational waves.
