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

[@1PrinceWilliam]

47:03 and I wouldn’t take any of that “sh….nonsense” either!

[@Cynyc-pq2pc]

I second and third this to the power of 83

[@5ftofFury]

I was about to comment the same thing! 😁

[@nativealien1859]

Made my Friday night

[@stevefromsaskatoon830]

Indeed 😉😊

[@MrBendybruce]

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

[@diamon999]

It's too short, perhaps?

[@stellarwind1946]

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

And you would know that how? To me this all seems like blabbety blab.

[@ChillSydneyWebSurfer]

hard as in concrete and can be applied in the real world or hard as in difficult-to-understand-theoretical-gobbledygook that will never be used more than for entertainment

[@anitareasontobelieve378]

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.

[@mylittleelectron6606]

Not sure if you've ever been to a blue state before, but high school kids there aren't exactly occupied with solving differential equations. And don't be too hard on your folks...no one was taught general relativity in high school.

Ummm you don’t sound unintelligent. Quite the opposite . Keep it up

[@jamescollier3]

thanks for the tremendous inflation

[@trout3685]

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.

[@malaydhar917]

A nice comment. -bmd

[@andthefunkybunch1466]

This feels like chatgpt

[@IndranilBiswas_]

@@andthefunkybunch1466 far from it!! This comparison is an insult to these two.

[@p__b__3749]

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.

[@albertmora4290]

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

[@corinnefeldmann5259]

My two favorite physicist together, a lovely gift.

[@Seb1066_]

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

[@ernstvanoeveren4361]

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

[@mgranahan]

The gayest passive aggressive fight I’ve ever scene

[@jimmydoolitle3764]

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 KZbin.

[@hakiza-technologyltd.8198]

I’m sorry to disappoint you, those guys are misleading ordinary individuals.

[@richardmcquade9832]

@hakiza-technologyltd.8198 Did you catch the part where they admitted to being incorrect in the past; and, where they openly welcome having their ideas challenged? Your Noble Prize in physics awaits you!

[@albertmora4290]

Ditto Jimmy. By the way, my Dad's name and my middle name is also James:)

[@garydecad6233]

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.

[@timveseli]

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

[@nvanderhoff]

I have a couple of his mind scape podcasts that I listen to more than once 63, 184 and 223 that last one a talk about explaination is just a mind blower

[@Eztoez]

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.

[@Dechral]

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

[@HD.369]

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🎉🎉

[@hakiza-technologyltd.8198]

No... they are misleading ordinary individuals

[@ralphhebgen7067]

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.

[@jballenger9240]

Lucky yo!!! The rest of us will just have to wait until the RI releases a KZbin broadcast.

[@user-xg1ie2kc9p]

At my house, plural of math, is, wait for it, .... math!! lol Now onto my "five a day". lmao. "Right". "Brillant". "Garden". A different world.

[@Bigbillyrayfan]

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

[@Bradgilliswhammyman]

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.

[@Dr10Jeeps]

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

[@alexcimpoiestamasan2537]

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!

[@smmfdftbh]

I am 40 years old and wish my love and fascination for science started when I was younger. No way I can change careers now, but I'm trying to learn as much as I can from videos like this

[@petermoore900]

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!

[@nurk_barry]

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 ❤

[@Robinson8491]

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

[@ahmadkoopal3120]

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 :)

[@HarryNicNicholas]

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.

[@SicilianDefence]

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

[@thomasdequincey5811]

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

[@CosmicDreamz139]

My favorite two science communicators together.

[@tursynh5021]

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

[@coreyleander7911]

Just read the comments on this video to see it is in fact doomed. Right wingers desperately trying to politicize physics and science.

[@bariizlam638]

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...

[@quarkraven]

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.

[@adrianfeeger]

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.

[@jonathon5075]

Cheers to both of these individuals

[@haroldfloyd5518]

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.

[@trevorjames2051]

Thanks for clarifying the entropy question I presented

[@luigicantoviani323]

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

[@williamjmccartan8879]

@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

[@shwetasinghnm]

These two are the best science communicators

[@W-H-O]

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

[@simay4977]

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

[@norcalpacific]

They originally attempted to do this interview in person, but the mass of their brains together in 1 room caused gravitational distortions.

[@judesalles]

You mean space distortion, right?

[@kquat7899]

Such a privilege to hear this conversation.

[@longlostkryptonian5797]

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!

[@user-he1yb7pl1w]

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.

[@broken_radar]

I enjoyed this so much! Thank you both

[@SANG0I]

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

[@YNVNEone]

I have to stop myself from hearing Alan Alda everytime Sean talks. It's crazy!

[@PlanetXMysteries-pj9nm]

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.

[@M0U53B41T]

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

[@sedatemern]

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

[@avinashsingh3013]

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

[@recurrencetheorem4264]

Sean is a true gem. Great teacher and inspiration.

[@cheriecica]

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

[@joyecolbeck4490]

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

[@iDanDelf]

Thank you! Amazing interaction... 🙏🏼

[@alanv8342]

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

[@aldenisouza2015]

I learned English listening Brian Greene.

[@timveseli]

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

[@kathyorourke9273]

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

[@darthmewtwo1759]

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

[@flyingarts6765]

DM gravitates so explain possible structures from coalescing DM. Even a DM black hole, what would that be like, for instance.

[@robertkazenel5498]

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

[@MarcMcMillin]

What a wonderful surprise to wake up to this treat!

[@artielundberg7125]

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.

[@HGALAXIES]

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

[@mimidhof2179]

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

[@jimxu1963]

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

[@pablogastonl]

Very nice! thanks for all the talks, sessions and conversations to expand scientific knowledge, approach and discoveries Will the September sessions be streamed live in the channel?? I am eager to watch them!

[@aaronmbowden]

I could listen to these two all day

[@scrubjay93]

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

[@lovelife6224]

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

[@charlesportney2137]

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!

[@despizedicon]

These two are something. They enjoy their time in front of any camera.

[@SandipChitale]

IMO there is confusion between - Entropy increases in the direction of time (makes sense because of the nature of state space) and it's corollary time direction is because of increasing entropy (NOT). I agree with former, not the later.

[@peterdamen2161]

Exactly, as I pointed out in my comment a few minutes ago. Both mix up entropy and flow of time (which doesn't exist, as the arrow of time doesn't exist),

[@steliosp1770]

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

[@horizonvariations]

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

[@euclidofalexandria3786]

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.

[@IndranilBiswas_]

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

[@euclidofalexandria3786]

Since energy is stored in space that is fractilized at the core, its data unpacking can perhaps be thought of something like normilization, you can probably use Collatz Theorem as well, to study energy unpacking out of compressed fractilized space. Frame dragging is the outer boundary, staggered energy and gaps of space.

[@PhilipRhoadesP]

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

[@paulc96]

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 !!

[@JustJunis]

Thank you for the Uploads! Maybe soon some about Quantum Entanglement; whilst Symmetry is broken, for Matter to do it's Gravity?!

[@JustJunis]

Maybe some big bounce, rather than a big bang in it. Not necessarily CCC

[@tobaidi]

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

[@euclidofalexandria3786]

Thank you again for posting 🙂

[@merlepatterson]

Something about the vacuum energy of space causes normal matter to fly apart rapidly (look at the very fast expansion velocity of thruster gas exhausted from rocket launches at dusk or dawn and from the rocket engine bell) makes it seem as though repulsion effects of molecular gas in a vacuum is the natural (dispersed) state of molecules/atoms/ions in a vacuum? Thus the reason the larger the rocket engine bell, the better (even a 1/2 mile wide if it were possible) to increase vectored thrust efficiency in a vacuum.

[@billyshawjr4038]

When you started talking about the arrow of time going in both directions it got me thinking. If we could get ourselves to move "backwards" in time, could that just mean that we stop moving in our own time and just start moving in the forward direction of a mirrored universe? Then when we stop our "backwards" time direction, we're right back at the same time as when started in our own universe?

[@ramkumar553]

Planck’s length polar photons, constructed of four brane and three brane strings, daisy chain into matter, gluons first, that can then fuse into the complex structures of leptons and baryons.

[@Raptorel]

I'm so glad that Brian mentioned the idea of very long random fluctuations that, just by chance, at some point end up just being uniformly distributed such that they start inflating: it's been my own idea on how the universe started from low entropy for quite some time. If you have fluctuations (although I'm not sure where this is happening - do you need an already existing spacetime where these fluctuations happen or do we have fluctuations of spacetime itself, like a "bubble" of spacetime with different energy distributions popping in and out of "nothing"?) that happen continuously, then at some point, just by chance, a particular fluctuation will have its energy distributed uniformly and in it inflation will start, expanding that bubble and not allowing it to collapse back. Since the positive energy in that fluctuation can be compensated exactly by gravity with negative energy, the fluctuation will have zero total energy and therefore will be able to live forever (here I'm referring to the uncertainty principle between energy and time). This way, only low entropy fluctations create universes, since only low entropy fluctuations can inflate, they are the only ones for which gravity behaves repulsively. So it's not a mystery why we started from a low entropy state.

[@Va1demar]

entropy is the flow of energy to a state of balance in relation to the system, so light loses its energy or, roughly speaking, goes out after covering vast distances, just like an electromagnetic wave attenuates over a distance

[@patbl61]

Two of my favorite brains together ❤

[@theresachung703]

Thank you for your work.

[@PositiveEnergy733]

Dear everyone, I wish you peace inside your soul. We are all light and all connected, don’t be scare, all gonna be ok. Your futur gonna be fantastic because you are fantastic. Thank you so much for your reading.

[@bericberlioz8096]

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)

[@keppela1]

This is the second video I've seen where Sean hypothesizes that the arrow of time may have pointed in the opposite direction in the "far far far past". I wish he'd make some attempt to unpack that as it's such a radical concept to throw out there with absolutely no explanation.

[@solutionrevolution7221]

Love your approach to sharing information. Great events. Any chance you come to Calgary, Alberta?

[@jimkane7162]

What a combo! Thanks WSF

[@hamentaschen]

"If I'm curt with you, it's because time is a factor."

[@jasonjarred5198]

“If it resonates with one of us, it will likely resonate with both of us” damn, sounds like some quantum entanglement between you and Sean!
