Two non-spinning black holes at the moment of merger give birth to gravitational waves — ripples in the very fabric of spacetime, captured by instruments developed with the help of Kip Thorne.
The universe hums like an orchestra: its notes are gravitational waves — ripples in spacetime predicted by Albert Einstein. The LIGO observatories, made exquisitely sensitive thanks to Rainer Weiss, strive to catch these whispers.
