Question

contribution of Indian scientists in the discovery of gravitational waves​

Answer 1

Explanation:

Indian scientists developed the theoretical modelling of gravitational-wave signals from black holes and data-analysis techniques used to detect weak signals hidden in noise in the subsequent waves.

The waves were first predicted by Albert Einstein a hundred years ago. In his theory of relativity, Einstein said gravitational waves spread at the speed of light, filling the universe. They are always created when a mass accelerates, like when ice-skater pirouettes or a pair of black holes rotate around each other.
