GW150914: first non-fungible token (NFT)GW150914 is a name of the first gravitational wave from a merger of two binary black holes that has been detected. The black holes were as heavy as 29 and 36 Suns, their collision occurred in another galaxy around 1-2 billion light years away from us. The signal was picked up by laser interferometer detector LIGO on the 15th of September 2014, hence the name. Later in 2017, Nobel Prize was awarded to Rainer Weiss, Kip Thorne and Barry Barish for their contributions to achieving this discovery.
