I count myself so lucky that I was able to work with this man, on the Advanced LIGO project.

Would have loved to have been present at the lunch table conversation where someone said "You know, if you build a really big interferometer, you could measure it." The original idea was first thought of in the 70s, project proposal in the 80s, funded in 1994, operational in 2002, nothing/tweaking nothing/tweaking nothing/tweaking,..... 2016 DETECTION! To anyone who worked on and contributed to this project, Thank-You 🙂

I remember as an undergraduate sitting in a quantum mechanics class with Bernie Schutz, and when the prof mentioned "graviton" most of us burst out laughing, but Bernie set out looking for it.

Mr. Weiss, You spoke of middle C...what note or frequency is the point at which the two black holes merge uniting with one another? Is it an interval or one note? I'm assuming it is one note... #stringaddict

I was reading Brief Answers to Big Questions just to relax a bit but the LIGO talk in the introduction amazed me. So now I' m here trying to learn more about it. 🤤

Stay on you carpet and wait when gravitational waves come. Then just expand in one direction and contract in the other

Please update this to include a reference to Kip Thorne talk. I found it but not without a flew searches. That said, This is such good work.

Weiss 'explains how LIGO works' but omits the crucial details. LIGO is the most sensitive system ever. To find a gravitational wave (GW) LIGO required innovative pattern matching software. LIGO developed templates for the expected 4 types of merger. All these waveforms in the video are an interpretation of the templates. LIGO can declare a GW for any event as long as the the template is found in the sensitive noise from the set of detectors. The implicit assumption is only a GW can affect multiple detectors. That assumption is wrong. On November 10, 2019, I gave LIGO a prediction for GW detections for 3 separate 5-day spans in November. LIGO reported 2 GW within 7 hours of my prediction for the first span; both subsequent spans were also confirmed with detections. The predictions were based on the lunar events expected in November. When the Moon is close to Earth or is aligned with the Sun there is an earth tide which creates a global surface wave by Earth's rotation. The first GW150914 was on the day of a perigee. The 2nd event was on the day of a new moon; the 3rd was near a full moon, 4th on the day of a perihelion. Every LIGO GW detection is near an earth tide event. If anyone wants to know what LIGO really detects, I captured my research and the confirmed predictions in this pdf. The pdf has a link to a separate pdf listing all the GW claims and their associated earth tide event. More than half GW are within only 2 days of the peak of an earth tide. LIGO has no independent confirmation for any of their GW claims. They neglected to consider a terrestrial source - the Moon! LIGO never explained how every LIGO claim coincides with waves of an earth tide. www.cultureandreligion.com/Detecting-a-Gravitational-Wave.pdf

This is like the linear version of a laser gyro. Like a laser accelerator. Though this still does not explain how you would measure at a nuclear scale.

They weren't directly measuring at that scale. They were measuring the interference of the wavelengths of the two lasers.

Dr. Thorne, who is now retired from LIGO. Dr. Drever, who has dementia and lives in a nursing home near Edinburgh, is not able to enjoy the victory lap. Dr. Weiss, who is retired with emeritus status at M.I.T.

3:47 that was such a disrespectful explanation. I wish he spent the entire talk explaining that, because you get complete morons (like everyone commenting here) who think they understand LIGO but don't actually know anything about it. If your explanation is that the arms stretch and light takes further to go through it, then you don't understand anything, even at the simplest level.
