|The LIGO Science Education Center has over 40 interactive, hands-on exhibits that relate to the science of LIGO. They host field trips for students, teacher training programs, and tours for the general public. Explore science concepts such as light, gravity, waves, and interference; learn about LIGO's search for gravitational waves; and interact with our scientists and engineers. LIGO Livingston is a working observatory, staffed by scientists, engineers and other professionals working intently to search out and detect gravitational waves from cosmic sources. The tour consists of a 20 minute video called Einstein's Messengers, a tour of the control room where the operating and monitoring of the interferometer takes place. You can interact with one of the scientists on duty and can ask questions about the research.
