Abstract:

On 14 September 2015, Laser Interferometer Gravitational-Wave Observatory (LIGO) detected a gravitational wave signal coming from the merger of a stellar mass black hole binary, recognised as GW150914. This discovery is a milestone in the exploration of the universe, which marks the beginning of a new era. This article discusses the issues relate to what is gravitational wave, how to detect it and the facts about GW150914.
