On 14 September 2015, the universe’s gravitational waves were observed for the very first time. The waves, which were predicted by Albert Einstein a hundred years ago, came from a collision between two black holes. It took 1.3 billion years for the waves to arrive at the LIGO detector in the USA.
A prize 1.3 billion (the gravitational waves), and over 100 years (Einstein’s theory), and 40 years (LIGO) in the making.
Rainer Weiss is the primary prize winner while Kip and Barry C. Barish jointly share the other half. Congratulations to all.
