India To Establish Lab To Study Gravitational Waves, Says PM Modi

In his monthly radio programme ‘Mann ki Baat’, Prime Minister Narendra Modi announced that India will establish a laboratory to study gravitational waves.

The move comes after the detection of gravitational waves recently.

The Prime Minister said:

“Recently the Gravitational Waves have been discovered by the scientific community of the world, which is indeed a major achievement. We should be proud of the fact that Indian scientists were also part of it. Keeping this in mind, we have taken a decision to open a LIGO (Laser Interferometer Gravitational-Wave Observatory) in India.”



So far there have only been two laboratories– Hanford in Washington and Livingston in Louisiana– for the detection of gravitational waves.

India’s laboratory would be the third one. It will come up in Pune.

The detection has paved way for knowing the outer universe, what happened in the distant past.


According to Albert Einstein’s theory, gravitational waves are formed when massive but compact objects like black holes or neutron stars collide and in the process, their gravity sends ripples across the universe.

He had predicted the waves 100 years ago. Devices like interferometers were used to detect them.


The proposed manufacturing of the laboratory is regarded as an essential step by the government.
