Exploration Center at LIGO (LExC)
The Laser Interferometer Gravitational-Wave Observatory (LIGO) is renowned for its landmark discovery of gravitational waves, cosmic ripples in space-time produced by ancient collisions of neutron stars and black holes.
Their cutting-edge science proved Einstein’s Theory of General Relativity, and earned them a Nobel Prize in Physics.
At the LIGO Exploration Center (LExC, pronounced like "Lexie"), immerse yourself in interactive exhibits that bring the wonders of the universe to life. Or, join a guided tour of the facility to gain insight into LIGO's ongoing research and its profound impact on our understanding of the cosmos.
