Up until 3 years ago I was familiar with Brian Green. Because of utube and Dr Tyson I became aware of two more. I am now familiar with six leading scientists that I can put into my lexicon of science . I am a 72 year old disabled Vet who is thoroughly enjoying the internet and the questions science is raising. Keep it coming guys...

I don't mind admitting I have a huge man-crush on Brian Greene. He is such an incredible educator. He makes complex and seemingly boring subjects feel magical, joyful and funny.

It’s amazing that a mere 4 years later we have proof of gravitational waves and a picture of a black hole 😍 what’s next???

@pigeonlarvamagoo8572 11 years ago

I love brian greene, he is the one who is inspiring me to go int o physics. I cant get enough of everything he does

@dapdizzy 6 years ago

One of the best science speakers and an amazing personality, Brian Greene. So much respect to him. He’s one of those people who attract and make you view him as a role model even though I’m not in this “role model” concept overall. Like the Higgs boson that brings pieces together and makes mass matter.

Brian Greene is the best moderator of science discussions by an inflationary order of magnitude!😍

@77matius 7 years ago

Dr. Brian Greene is one of the best! Thanks for all your hard work, Dr. Greene.

Einstein was figuring all this out in his mind while people were still traveling on horses, discovering & understanding time dialation & length contraction by doing thought experiments, at a time when spaceflight was but a dream. Genius doesn't seem to do him justice, & it makes Newton & all those others even more astonishing when you consider how long ago they were figuring out all the different laws of the universe, when man's knowledge & scientific understanding was so limited, extraordinary mind's that one can but appreciate, marvel & envy. Bravo.

Wish I d meet him once in my life, Dr.Brian Greene

@LarryFasnacht 7 years ago

I could listen to Steven Weinberg all day. What an amazing intellect. I would love to take a class from him and can’t believe he is still teaching. I would love to know what he meant when he said that he doesn’t look at the pictures, they are misleading (or words that I interpret that way).

@hansrudolf7212 7 years ago

I wish this group will sit together once more and talk about the same stuff , knowing that we now actually have the first pictures and scientific evidance of black holes and the ripple of time and space 😊

@martin6ariza 7 years ago

2 months after this video was published gravitational waves were detected. I love science.

@yohanalaiser2667 8 years ago (edited)

I have never watched almost 2hrs clip on youtube sacrificing my night sleep...and I am taking Bachelor of Doctor of Medicine like what am I doing here...but I can say Physics has found its Spokesmen...The ones I can listen to....bravo Brian et al

Much appreciation from Tanzania

@musicilike69 2 years ago

I love these sort of talks. One of the coolest things about the internet is we can tune in and listen to the Einstein's and Newtons of our time.

@MrAkashvj96 8 years ago

Prof Weinberg is such an eloquent speaker. Prof. Samir isn't far behind.

@JoshEwaDavinePhotus 5 months ago

This is my favorite one.

@3dgar7eandro 4 years ago (edited)

55:55 I come from the close future and we have finally detected the gravitational waves:):) Just as Einstein predicted
This is just what the worlds needs a group of people all over the planet talking about science in a calm manner.

@NanDrummer 8 years ago

Man what a panel of guests.

@jeffmckinnon5842 6 years ago

thank you science guys. These YouTube videos really get people thinking and you never know where the next great ideas will come from. Hopefully programs like this will help to seek out the next genius to fill in some more of the picture. I'd love to be a fly on the wall to see what the next hundred years will bring
