GEO600

GEO600 is a gravitational wave detector located near Hannover, Germany. It is part of a global network of interferometric gravitational wave observatories that aim to detect gravitational waves, which are ripples in spacetime caused by massive astrophysical events like merging black holes or neutron stars. GEO600 consists of a 600-meter long L-shaped interferometer that uses lasers to measure minute changes in distance between mirrors positioned at each end of its arms.
