What will I see?

During your visit you will have a chance to explore the interactive and static exhibits in the LIGO Exploration Center (LExC), including the historic Weber Bar (one of the earliest devices designed to detect gravitational waves) and a full-scale engineering model of one of initial LIGO's suspension tables, showcasing not only the evolution of LIGO, but gravitational-wave detection as a whole. You will also visit the one point on the site where you can see both of the interferometer's 4km-long arms reaching into the Eastern Washington shrub-steppe. A highlight for many guests is the interferometer's control room, where you will learn even more about LIGO directly from the people who maintain and operate the world's most sensitive measuring device. Questions enthusiastically welcome!

Additional things to note:

• Visitors do not require any special badging to visit LIGO.
• Entry begins 15 minutes before your scheduled tour time.
• The outdoor walking tour lasts about one hour. Guests should dress for the season and wear comfortable walking shoes. The total distance of the walking tour is about three quarters of a mile.
