Question

The Nobel prize for physics in 2017 was awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne, their contribution for winning the award related :

• A. For decisive contributions to the LIGO detector and the observation of gravitational waves.
• B. For the prediction of gravitational waves with the help of general theory of relativity
• C. For detecting a huge Black hole in the centre of Milky Way, galaxy.
• D. For theoretical discoveries of topological phase transitions and topological phases of matter.

Answer 1

Answer:

A. For decisive contributions to the LIGO detector and the observation of gravitational waves.

• The 2017 Nobel Prize for Physics has been awarded to Rainer Weiss, Barry Barish and Kip Thorne for decisive contributions to the LIGO detector and the observation of gravitational waves.
• In February 2016 Weiss, Barish, Thorne and colleagues working on the Laser Interferometer Gravitational-wave Observatory (LIGO) in the US announced that they had made the first direct detection of gravitational waves.
• The observation was made in September 2015 and the gravitational waves had been created by the merger of two distant black holes.
