LIGO

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves. Prior to LIGO, all data about the universe had come in the form of light and other forms of electromagnetic radiation, from limited direct exploration on relatively nearby Solar System objects…
