"LIGO" - Director's Cut

I'm so happy that there are some documentaries produced with the volume of the background music set to actually be in the background and not drowning the speech👌

Hells bells I needed this documentary. In a troubled world, this reminded me of the purity and nobility of scientific enquiry.

I live only 30 minutes drive from the Hanford LIGO. They do monthly public tours. And if you have a group of 15 or more, you can schedule a private tour. I did that with my grandkids. Fantastic! Worth a visit to Richland, Washington on the Columbia River. The Pacific Northwest National Laboratory is another great center of science research here. And then there is the B Reactor, the first operational reactor on earth, created for the Manhattan Project, part of the Manhattan Project National Historical Park, and the Park Service gives tours. Very worthwhile. John Wheeler who taught Kip Thorne, did much of the theoretical work behind LIGO also worked on the B Reactor.

It's 5:15 in the morning and I couldn't sleep. I started watching this video and I was enraptured. I've always been fascinated by science and have, since I retired, concentrated on learning about fields that interest me. Physics has been my big challenge (mainly the math) but this video opened up an entirely new way of thinking. I was impressed not only by the concepts but the clear presentation of the approaches taken to prove those concepts was fascinating. So, I am saving this video to watch again because I know that there is much I missed or didn't understand and I want to understand. Thank you.

Bravo! ....what a beautiful film. The signing of the book with all the signatures of earlier Nobel winners took my breath away. Great documentary.

It’s amazing to see the universe through the lens of gravity! It’s also ironic the LIGO uses light to detect the waves of one the few non light mediums in order to shed new “light” on science.

the utter beauty and also the sheer madness of human beings and what we are able to do

I am pleased that humanity liked the results. It gives inspiration for further research and development. And there are bigger surprises.

Thanks for an excellent documentary of the awesome LIGO instrument.

Thanks for the wonderful video, and a huge thanks for not ruining it with crappy background music. I don't know why some people are compelled to add annoying background music throughout their videos.

Thanks for this release - such an excellent tale of scientific endeavour, now with more of my favourite characters - in HD! ❤

An outstanding documentary! ❤

Great documentary, hope it ends up at something like PBS NOVA so more people see it!

I can't believe that this awesome movie is free! I love all you smart nerds! I'm a hobbyist physicist.

It heartens me to see these big scientific search projects being funded. Amazing.

Great stuff. I'm only 8 minutes in and I'm already thinking the same thing I was thinking about this kind of detection before - you really need to have a detector station up past earth's local influences... We need something like the JWST up there for LIGO...

This is fascinating! It's almost too believable that we humans can now detect massive cosmic events that are NOT by means of electromagnetic phenomena, which, since the dawn of human existence until 2015, were the only possible means of sensing electromagnetic waves rather than gravitational waves.. It boggles the mind and it lifts the spirit! What unimaginable wonders await us, if we survive our petty squabbles here on this little sphere we inhabit..

Exceptional documentary.

One of the great achievements in experimental physics. I am sharing this with all my physics students.

Bravo to all those involved!
