A century ago, Albert Einstein developed his theory of relativity, and in recently proving it, MIT physicists discovered a new way for us to listen to and understand the universe. Rai Weiss, a Nobel Prize winner in Physics, and MIT professors Nergis Mavalvala and Scott Hughes describe the process of creating a device to measure gravitational waves, providing a fascinating glimpse at a famous theory, a professor's last-minute lecture idea and some questions about where we might take this discovery in the future.
