Brian Greene and Sean Carroll together at last?! Yes please, and thank you!

Wow what a treat to have these two together. Two of the brightest and most articulate communicators of hard science.

I mean, two of my all time favorite science outreach educators both together on the same podcast. What's not to like?

As a mom in a red state you will never know how much these talks mean to me. We weren't taught JACK about this..and me especially so. My town was so small one of parents were my teachers except for 2 years and they are YECs. They mean well but the misinformation they believe and Pure D Brand Lack of Attention, combined with zero concept of curiosity, and adherence to dogma, made me pretty stupid. When I listen to science communicators I learn so many concepts and can understand more. I'm sure students who can do the math love them, too. Your lack of all bragadocio, humbleness, combined with your degrees, and easy manners, help folks like me that were controlled to the Nth degree, I truly am thankful I can learn a bit. Thanks so much.

I really enjoyed watching Sean Carroll and Brian Greene's conversation. More than just the interesting physics and philosophy topics, I was fascinated by how well they conversed together. They clearly listened attentively to each other, connected on ideas without talking over one another, and had a smooth, engaging back-and-forth flow. Their respectful yet vibrant exchange of perspectives was not only intellectually stimulating but also a lesson in having a thoughtful, enlightening dialogue. Inspiring.

My two favorite physicists (so far). Loved them in Sean's Mindscape podcast. These two talking about their field of expertise will never get boring or old.

My two favorite physicist together, a lovely gift.

These two geniuses are among my two favorite living physicists. Brian Greene and Sean Carroll are saints in my definition of the word. Here's my definition. Saint: Someone who devotes their life to pursue Truth. Thank you Brian and Sean. I love you with all my heart. Albert Mora

This was so good. Two great scientists and scientific communicators grappling with some big themes. I loved it, thank you both

I'm going to need another 40 hours of conversation between these two. Thanks for sharing

Brian and Sean… the 2 best online physics tutors! Excellent guys

What a pleasure to listen to this, especially in the times of the horrible news today. This is why we can be proud to be scientists.

Absolutely brilliant. Fantastic that Dr. Greene provides the opportunity for the audience here to learn from the greatest minds of our generation. I always watch, listen and learn. Sean Carroll is one of my favorites and these two together are definitely a treat. P.S. for Dr. Greene. Lenny Susskind is one of my favorites too. I am a nuclear and electrical engineer by profession and I took the time to watch Lenny teach QM on video from Stanford. I really enjoy it when the two of you get together and I especially love his Feynman anecdotes. Please do something again with him soonest. I have watched everything you and Dr. Susskind have done on KZfaq.

Brian Green my all-time favourite scientist not because of scientific temperament but because of his enthusiasm and passion to teach the World 🌎 This show actually justifies the name "World Science Festival " because real Festival is something that is not limited by a closed circle or group rather it is being celebrated by the Whole World 🌍 This show encourages the World scientific minds. It's great 👍 Both the Cosmologists rock show🎉🎉

My two heroes. ❤ Fascinating that chemists in 2005 thought E=mc^2 was irrelevant to chemistry. I distinctly remember learning in school in the 90s that the energy I/O in a chemical reaction was directly determined by the mass difference according to E=mc^2. I guess i had a pretty good science education!

Listening to two very intelligent and articulate human beings is sheer joy!

Sean is a great guess. His recent 4+ hours podcast on physics was amazing.

Two legends of the physics community! Absolutely loved your talk ❤ please more

These two guys are my favourite science communicators - I attended Sean’s talk at the Royal Institution in London the other week and he was absolutely brilliant. What I love about his style is that he tries to make the maths behind the formulae approachable. Of course it won’t replace a university degree but a layperson with some mathematical background (perhaps A-level, college general studies level) will develop a far deeper understanding of the subject than they might get from reading journalistic articles or some of the books in the pop-science genre that are out there. I think Brian and Sean do a great job also in getting young people to study science, maybe those who are ‘on the fence’, who have an interest in the subjects but are unsure about a full-blown university degree. To those, listening to their excellent podcasts and reading their books must be like fanning the embers of a fire.

I have just decided recently at 30 years old that physics is the field i want to pursue my whole life and everything around this seems to be disappointing and trying to make me quit believing the I actually can. Thanks for the words from the ending, i will definitely continue without any care of what others think. I'll come work with you soon!

Scintillating conversation! I love this because it feels like they are genuinely speaking to each other, sharing and learning themselves, even as they teach us.

The only path out of this in my mind, that truly seems to fix the low entropy / early universe problem is something akin to Pentose’s Conformal Cyclical Cosmology, where the scale of the late high entropy universe no longer means anything, and you end up with a point where space ends up naturally falling back toward what looks like another big bang. I know there might be issues with it, but it’s one of the few ways out that could make sense. Brian and Sean, both of your collections of books have inspired me greatly! Much love ❤

professor Sean Carrol is my favorite physicist in the world. He is such an awesome science communicator..Brian green is also legend as well...hyped fork this discussion...

Two of my three most favourite science presenters in one video . Yay!!!!

My 2 favorite science explainers and media personalities in the field doing a conversation together ! Sean is such a breath of fresh air, he brings a erudition and clarity that is missing.

Two of my favorite authors and science guides! I am very indebted to you both. I’ve learned so much from you and consider it all priceless! Thank you. Thank you. Thank you!

My favorite two science communicators together.

two of my faves! I could listen to you both for literally hours

Thank you both so much, I am profoundly grateful for your generosity of spirit.

Love Sean and Brian, they both have done this so much and are very skilled at public science information and should be rewarded for their incredible contribution to public general knowledge.

Two of my favorites at once! Really excited to watch this! Thank you so much for making these videos!

This is an example of a real conversation. Inspiring, thought-provoking, and humbling.

@worldsciencefestival thank you for providing this space and sharing this conversation, thank you Brian and Sean for allowing us to listen in on this conversation. Peace

I love listening to conversations between these two. They are always thoughtful, informative and entertaining.

My two favorite KZfaq channels in one session. What a bless

I learned English listening Brian Greene.

Sean is a true gem. Great teacher and inspiration.

what is great is that these two don't always see eye to eye, but the discussion keeps us all honest, if they have to argue, then that means they are sincere.

I’ve spent a lot of time with both you gentlemen, both online and between the pages, and I for one thank you for making the cutting edge accessible to folks like me.

I enjoyed this so much! Thank you both

Please broadcast the talk between you, Sean and Carlo Rovelli of the 23d of september. We need it ❤

The best physicist duo ❤ what a treat to see these two discuss many topics I know nothing about

What a combo! Thanks WSF

These two are the best science communicators

These 2 are just awesome..hope to keep getting more.

I truly love these two men. So good to see them together!!!!!❤❤❤

I could listen to these two all day

Great stuff! - I love listening to these guys talking about these big questions!

wow what a treat my two favorite bedtime story tellers

You are my two favorite guys! Thank you so much.

Hi professor brian green and sean caroll is my favourite physicist and science communicators I have been watched their videos for nearly four years when I was in my secondary High school

Thank you gentleman, pure fun and nice to see Physics, Philosophy and Cosmology coming together. Kim

Listening to these smartest gentlemen gives hope that humanity is not doomed...

This will be awesome. 😊

It is an absolute pleasure listening to these two guys together. Both are superb communicators and experts in physics. I would love to see these guys get something on regularly.

Sean is a good science journalist. Thank you Sean for all your contributions.

This was a fantastic and engaging show all the way through! Thank you.

The collab I didn’t know I needed 🤘🏽❤️

brilliant.. inspirational to see such passion and knowledge - would be great to have more talks like this between Brian and Sean, keep them coming! Thank you so much for the efforts, such an amazing channel.

What a wonderful surprise to wake up to this treat!

Such a privilege to hear this conversation.

I watched KZfaq and took a shot every time Sean Carroll said “many worlds.” In one of those worlds, I was dead within 30 min.

Just saw this and I’m totally geeking out right now 😅

Thank you! Amazing interaction... 🙏🏼

I'm constantly amazed by your content, sparking my curiosity to dive deeper into the enigmas of the cosmos. Thank you for fostering my sense of wonder.

Wow! So excited for Saturday. You two are SO good together ❤

Thank you posting, I appreciate your effort in making these videos, and posting them. Have a great day, and find the Eternal part of the day, known as joy.

Cheers to both of these individuals

Listen to the wisdoms... I'm so enjoyed and educated. Thank you, both!

Brian. Please keep up this great work. Sharing your knowledge like this is a treasure to society. Let me know how I can support.

It's amazing when you have two of the top brains of the history discussing universe! 🎉

Thank you again for posting 🙂

Loved the discussion around philosophy. Totally agree with your views!

You and Sean are two of the greatest ppl in my book in modern history. I just love ppl like you and Sean. We need more ppl like you and Sean, but you ppl are rare :)

Thanks for clarifying the entropy question I presented

You don't get better than this. The two Audible and Patreon greats!! ❤❤🍿🍿

Thank you for your work.

Love Sean Carroll, we are lucky to have him in the science community. He has a fantastic understanding of all the models and I love how he can explain things clear and concise. I'm one to believe that we could have Many Worlds and CCC both be partially right. I don't see why there couldn't be Many Worlds as well as Cyclic Cosmology. Both really explain different things. Many worlds explains Quantum weirdness and probabilities and CCC attempts to explain the start of the universe and end.

my 2 favourite people in science! i hope the live event will be filmed and uploaded on KZfaq!

Perfect conversation for a relaxing evening of astrophotography. Thanks guys.

Thanx a lot Mr. Greene.

Watching on repeat-but this is keeping me from getting to my wordle! 😂😂😂. Agree-easier to watch together than have to watch them both and say-oh yea those two are on the same page.

Brilliant. Realistically, what can I hope to add to what's already been said below / before. I would guess that most of this audience are fans of one or both, of either Brian Greene or Sean Carroll anyway. There is also a Mindscape episode where Brian is the guest. That is pretty good as well - and I'm sure it is still available on Sean's Mindscape Channel. And they have both written some great books - especially in high-quality, popular science for the non-specialist. Many thanks to both Prof. Brian and Prof. Sean. for sharing this enlightening conversation. Please do this again soon, when Entropy is just a bit higher !!

Thank you for this.

Absolutely the best!

Be welcome. Simmetries and concepts also, as ever, we are inspired by the sum of your communicating efforts and hope in other people 🙏🗽 Aware of our belief, continue, never stop, like inertial movement in a particular medium. You both are looking great👌.

Alright let’s start

thank you WSF

Two of my favorite brains together ❤

Two easy guys to hear out. Thanks lads.

Just hangin out with two of my favorite guys. Great talk.

Glad to listen them thank you

Great discussion. You guys are a treasure.

Thanks WSF .

Always great to see Brian and Sean share their thoughts. Would be interesting to meet them over a beer and see how things go.

Very enjoyable exchange!

yeah, that was pretty awesome watching these two lob tennis balls back and forth. wish I could have seen them in person. going to take some of their online courses!

I am fascinated by this. So fascinated that I went to the WSF website to see if I can quickly fly into NYC On Saturday!! ( I am a brand new attending physician :D)

This is awesome.

I have the Oppenheimer soundtrack playing in another window as background music while Brian and Sean are talking and it's just awesome.
