LIGO is the world’s largest gravitational wave observatory which exploits physical properties of space and light to detect and understand origins of gravitational waves.
· LIGO Significance
Ø LIGO offered unexpected insight into the cosmos
Ø detect events like black hole collisions
Ø untangle mysteries about the dense, dead objects known as neutron stars.
Ø solve a long-standing debate about the origins of precious metals, such as gold and silver, as well a other heavy metals.
· Contribution of Indian Scientists
Ø India can boast of three decades of research at Inter University Centre for Astronomy and Astrophysics (IUCAA), Pune and Raman Research Institute (RRI), Bengaluru, at the frontiers of theoretical modelling, and developing algorithms for signal extraction, in the quest for discovering gravitational waves
Ø The development of a signal processing method called Matched Filtering – a key analysis technique needed for this detection, (pioneered at IUCAA) the estimation of black hole binary parameters, in improving the estimation accuracy of black hole spins, efficient methods for handling instrumental artefacts, and electromagnetic follow-up with X-ray instrument onboard AstroSat

Second part of the answer should have been on contribution of Indian Scientists not on benefits. Keep Writing.
