LIGO: Laser Interferometer Gravitational-Wave Observatory

On 14 September 2015, gravitational waves from the cosmos were observed for the very first time. These vibrations in spacetime, which were predicted by Albert Einstein a hundred years ago, came from a collision between two distant black holes. The gravitational waves had travelled through the universe for 1.3 billion years before they were discovered by the LIGO detectors in the USA.
