LIGO, or the Laser Interferometer Gravitational-Wave Observatory, is a large-scale scientific facility designed to detect gravitational waves, which are ripples in spacetime caused by accelerating massive objects like merging black holes and neutron stars. By using laser interferometry, LIGO measures tiny changes in distance as gravitational waves pass through Earth, allowing scientists to observe cosmic events that were previously invisible, thus enhancing our understanding of the universe.
congrats on reading the definition of LIGO. now let's actually learn it.
