UPSC NDA-1 – 2019
The correct option is A) Laser Interferometer Gravitational wave Observatory. LIGO is a major scientific collaboration dedicated to detecting gravitational waves.
– LIGO stands for Laser Interferometer Gravitational-Wave Observatory.
– It is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave science as an astronomical tool.
– LIGO consists of two large observatories in the United States (Livingston, Louisiana, and Hanford, Washington) that work in tandem.
LIGO achieved the first direct detection of gravitational waves on September 14, 2015, from the merger of two black holes. This detection, announced in February 2016, confirmed a major prediction of Einstein’s general theory of relativity and opened a new window on the universe, leading to the Nobel Prize in Physics in 2017.
