Nearly every day we read articles about great, scientific discoveries, and quote science facts we read or hear from friends. We use advanced technology in the palm of our hands that not too long ago was born of a science experiment. When we take a break from our busy lives, we sometimes ponder what lies beyond the tangible universe, out there, among the stars. How many of us have spent time, side-by-side with the researchers and scientists who dedicate their lives to understanding distant, cosmic events? Inspired by the LIGO Scientific Collaboration, funded by the California Institute of Technology LIGO, A Passion for Understanding celebrates the dedication of those who have worked for nearly three decades on a single science experiment. In this film, we witness the installation of instruments designed to prove the last piece of Einstein's theory of general relativity, and come to understand what scientific discovery means for us all.
