Virgo interferometer
Gravitational-wave detector in Italy
The Virgo interferometer is a large-scale scientific instrument near Pisa, Italy, for detecting gravitational waves. The detector is a Michelson interferometer, which can detect the minuscule length variations in its two 3 km (1.9 mi) arms induced by the passage of gravitational…Source: Wikipedia (CC BY-SA)
