In 2016, the LIGO-Virgo scientific collaborations announced the detection of two gravitational wave signals by the Advanced LIGO observatories. The existence of these elusive ripples in the spacetime was predicted by Albert Einstein a hundred years ago. At times, even Einstein doubted the existence of gravitational waves in nature and never imagined that they would ever be detected. The signals observed by LIGO were inferred to be produced by the merger of two binary black hole systems in the distance universe. This opens up a new branch of observational astronomy that is unique in several senses. This lecture will tell the exciting story of this discovery, what went behind, and what lies ahead.
