this is truly revolutionary. MIT never fails to impress!

Hello please keep uploading these types of videos. I saw it 4 years ago and today it popped up in recommendations today ❤

[srikarmukkamala]

The fantastic Physics takes us through a miraculous discovery in nature. The last question by Prof. Weiss made me get goosebumps!!

[SUMITGUPTA-wdkc]

👏👏👏👏👏
This is how a student want like to study hello professor..
Thanks to share your own experience. with students who are part of college

[RvrRaiderD]

Well done 👏Weiss's line at the very end hit me right in the gut.
You can see passion for the future of science in his eyes, and the mortal pain of not being around to see it.

This was a MAGNIFICENT video of amazing quality! Looking forward to more inspiring ones like this 👍

[abhineetagarwal]

Thanks YouTube, for suggesting this. Good going, Dr Weiss.

[PhysicsNomad]

This is the best science documentary I have ever seen!!

[yingdongduan]

Pay my great appreciation and respect for those who love and insist science exploring!

[MrBikashchachan]

A very very great video....this should be recommended to everybody....its a thousand times better than a movie and is definitely needed to be watched

I feel good be the first ever subscriber of this channel.

Thank you😊 So cool loved it! Wonderful to see how it was put together !

[i.m.Q.]

I'm looking for something somewhat specific here as I've seen the chart like the one at 10:02 before; im confused here. I have a background in DSP, and I'm trying to put things together before I write a formal paper and research concurrently.

Every chart I see has frequency as the range. I see the time domain (which im assuming is observed time vs proper time). I don't see anything labeled energy. Unless there are 2 plots, the top most plot being frequency and the bottom the standard time-energy plot, it doesn't quite add up. I just noticed the 2nd plot here as other places seem misinformative for whatever reason(s).

The screns on your computer scene and the shot from the research paper seem inline with what I'm looking for. Do you know of a credible source where I can find the time-energy plot itself of some given gravity wave? If I had clarification on the one with 2 observatories, that might be perfect.

Also as a side note, I swear you guys at MIT are the only people that have as expansive, detailed and credible technical information on here. It's been of huge help to me to promote understanding. Now and then I'll come across something comparable from Cal Tech, but you guys have them beat hands down. Thanks in advance!

[yasheshratnakar]

Extremely concise and self explainable.

[bhavinpithawala]

sorry for being late, but thank you so much for this finding.

*Trust me, * You can have 2nd Albert Einstein,
*BUT NOT 2nd Rainer Weiss.*

[monishravulapally]

I think people still don't realise how important his foundation was. The cosmos will be looked from a whole new perspective from now considering these breakthroughs. And its sad to see people like weiss Ageing. He resembles brilliance to the infinity.

[martinabiber]

thank you for sharing, sometimes i can feel them . and sometimes i feel how the puls of earth change. not knowing but thinking of the possibility thats the answer is great and wonderful. i hope someday you can show how it affects people, because it goes through everything.

[meet_cine]

A great video indeed. I have watched tens of videos of Ray Weiss and about gravitational waves but this one just made me skip a heart beat.

[piyushgupta]

It's the greatest discovery, great 🔥
