LIGO and the birth of gravitational-wave astronomy with Gabriele Vajente - Ep 13 - Rays and Waves

1.3 billion years ago, two black holes collided in a distant galaxy, sending ripples through the fabric of spacetime. On September 14, 2015, those ripples finally reached Earth and humanity detected gravitational waves for the very first time.

In this episode of Rays and Waves, Daniel and Steven sit down with Dr. Gabriele Vajente, Deputy Head of Systems Science and Engineering at LIGO, who was a postdoc on the project during that historic detection. For more than fifteen years, Gabriele has been at the center of the groundbreaking technologies and discoveries that have opened an entirely new window on the universe.

We explore how LIGO’s exquisitely sensitive instruments can measure distortions thousands of times smaller than a proton, the optical engineering innovations that make it possible, and what gravitational-wave astronomy reveals about some of the most violent events in the cosmos. At the heart of it all are the people like Gabriele who’ve dedicated decades to pushing physics and engineering to their limits.
