Watch How Gravitational Waves Dance across the Universe

LIGO scientist David Reitze takes us on a 1.3 billion year journey that begins with the violent merger of two black holes in the distant universe. The event produced gravitational waves, tiny ripples in the fabric of space and time, which LIGO detected as they passed Earth on September 14, 2015.
