This Hackaday Remoticon Keynote as presented by Dr. Keith Thorne on Saturday, November 20th, 2021.

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is literally looking for ripples in space-time that you know as gravitational waves. The challenges of building, operating, and interpreting such a device are manifold. These interferometers are the highest precision devices ever devised, able to detect motion 1/10,000 of the diameter of a proton! To get there, the mirrors need to be cooled to 77 nano-Kelvins. Getting the most out of it is what Keith and the rest of the team specialize in. This has included things like hacking the Linux kernel to achieve a sufficient level of real-time digital control, and using “squeezed light” to improve detection sensitivity in frequencies where quantum mechanics is getting in the way.
