The
Laser Interferometer Gravitational-wave Observatory (LIGO) works by
detecting tiny differences in the length of two laser beams. Just how
tiny are these differences? About 10,000 times smaller than the diameter
of an individual proton. At the World Science Festival's annual On the
Shoulders of Giants address, LIGO pioneer Barry Barish put the
detectors' extreme sensitivity into mind-blowing perspective.
