The gravitational wave is the time dependent perturbation in the spacetime. The discovery of Gravitational wave by LIGO not only proved the GTR but also opened a new era of astrophysics. It has some advantage over the electromagnetic and sound wave, which is helpful to detect merging of the black hole at very large distances. LIGO-India project will be helpful in prescribing proper location of the source of the gravitational wave. As LIGO with longer arms are very difficult to make, so it is...Read Full Text | Download PDF
