Parsons congratulates Rainer Weiss, Massachusetts Institute of Technology (MIT), and Kip Thorne and Barry Barish, the California Institute of Technology (Caltech), of the Laser Interferometer Gravitational-Wave Observatories (LIGO) team for winning the 2017 Nobel Prize in Physics! We’re honored to have provided design and construction management for LIGO facilities including 4-km-long laser tubes to detect gravitational waves, and used a building information modeling process to help Caltech and MIT scientists visualize and engineer the facilities.
