The discovery of gravitational waves in LIGO (Light Interferometer Gravitational-waves Observatory) was ground-breaking. Suddenly, experimental astro-physics has not just eyes, but also ears to listen to events that shake the sky, yet occur in complete electromagnetic darkness, such as collisions of black-holes. I will overview the recent observation of a violent black-hole collision 1.3 billion light-years away, and provide an overview of this truly amazing device that relies on optical interferometry to detect miniscule ripples in space-time with relative sensitivity of 10-22 ! I will discuss the plans to enhance the LIGO sensitivity even further using quantum squeezed light.
