India will soon be working on a detector that will detect tiny waves in the fabric of space-time. Recently, the government has sanctioned Rs 2,600 crore for starting a new gravitational wave observatory in Maharashtra. The observatory will work in conjunction with four similar facilities around the world. The observatory is expected to be completed by 2030.
"It will enhance our astronomical capabilities and enable us to provide input and feedback not only to India, but to the rest of the world," said Union Minister Jitendra Singh.
Once ready, India's research facility will join the network of observatories, the Laser Interferometer Gravitational-Wave Observatory (LIGO), which will search for any obstruction in the fabric of space-time is. These interruptions are cosmic signals from some of the most violent events in the universe. Space time consists of three things- magnetic field, radiation wavelength and gravitational pull.
When massive objects like black holes or neutron stars move, their motion creates gravitational waves. Scientists use LIGO detectors to search for evidence that gravitational waves have passed through the Earth.
For example, in 2015, LIGO scientists detected gravitational waves from black hole mergers for the first time. The discovery confirmed Albert Einstein’s prediction that space and time are not separate, but woven together in a fabric-like structure.
