India to house the World’s third Gravitational Wave Detector


According to a report in Hindustan Times, India will house world’s third Laser Interferometer Gravitational Observatory (LIGO-India) to detect gravitational waves, similar to the two detectors in the US. Maharashtra and Madhya Pradesh are among the states shortlisted for the experiment.

The Prime Minister Narendra Modi, tweeted about the same earlier this morning; saying “Hope to move forward to make even bigger contribution with an advanced gravitational wave detector in the country.”


At an estimated cost of Rs. 1,260 crores, the project has been studied by the department of atomic energy and the department of science and Technology. The Planning Commission is reported to have cleared the project.

This observatory will help spot more gravitational waves; enabling better study of the general theory of relativity and blackholes.

Once this happens; LIGO-India will put the country on the global network of gravitational wave detectors.

If the Indian observatory — LIGO-India — materialises, the country will join the global network of gravitational wave detectors. India’s geographic location with respect to the existing observatories is very important as the larger the distance between the observatories, the greater will be the precision in detecting gravitational waves.

“Without LIGO-India, we can’t locate where the event happened. Therefore, three identical telescopes are needed, said professor Tarun Souradeep, of the Inter University Centre for Astronomy and Astrophysics in Pune.

The Indian Institute of Plasma Research in Gandhi Nagar is among the lead institutes to build components for the Indian detector for central data acquisition and control for the futuristic machine.
