 *************************************************************************
This session is explained by Mr K.V. Paurya, Expert Faculty at Drishti IAS, who presents a clear and structured analysis of gravitational waves from a UPSC perspective. Gravitational waves were first predicted by Albert Einstein in 1916 as part of the Theory of Relativity, where disturbances in space-time caused by massive cosmic events such as black hole or neutron star collisions generate ripples that travel at the speed of light. These waves were directly detected for the first time by LIGO, a major scientific breakthrough that led to the Nobel Prize in Physics in 2017. The video also explains major global observatories such as VIRGO in Italy, LISA by the European Space Agency in space, and KAGRA in Japan. In addition, it provides detailed coverage of India’s ambitious LIGO-India project, including its location in Maharashtra, funding, participating institutions, and its importance for scientific research. Understanding gravitational waves helps scientists explore key cosmic phenomena such as black holes, supernovae, and the origin of the universe, making this topic highly relevant for UPSC preparation.
