The full inside story of the detection of gravitational waves at LIGO, one of the most ambitious feats in scientific history.

Travel around the world 100 billion times. A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don't know if this infinitesimal event will come next month, next year or perhaps in thirty years.
