Sean Carroll on the Biggest Ideas in the Universe | Closer To Truth Chats 

Sean Carroll is the one who will explain to you in the simplest way possible while still discussing the most profound ideas in physics. This is a rare rare rare talent and he is an absolute champion!!!

When the Covid epidemic started, Sean did a series of lecture that I listened to not really understanding much. I really appreciate his continued effort to educate me , the ordinary curious human. Also I have watched many of Robert’s interviews. It is evident that he understands a great deal. Thanks to both of you from a little old lady in Indiana.

Robert, that was an exceptional job understanding the material before coming up with the questions, and letting Sean do most of the talking. Your best interview ever.

Carroll’s a marvelous teacher, mainly because he thoroughly understands his subjects. His book “Something Deeply Hidden” opened my eyes to Everett’s Many Worlds interpretation and convinced me that it is our best interpretation of quantum mechanics so far.

I love Sean Carroll and this is one of the better talks I've ever seen him have with anyone. You did a great job at covering so many topics in a single interview Robert.

I love Sean Carroll, I could listen to him explain stuff all day.

Sean Carroll is a charismatic explainer of whom there are not so many. Thank you very much.

Haha, I love that. "No one in the visible universe could buy your book." This actually makes me want to buy it more. I did sit through his biggest ideas lecture series through the pandemic. I have a strong math background but less exposure to physics, and I appreciated that he didn't avoid mathematical reasoning when explaining topics. I've followed Sean for a long time, initially because he was impressive in science discussions online, but I've grown to really appreciate his considerations on other topics like democracy and ethics as well. Easily my most respected public intellectual. Thanks for having him on.

Just love Robert's style, voice and intellect.

Sean is such a communicator!

an incredibly rich discussion and I really enjoyed the format of racing through the biggest ideas of the book of the biggest ideas in the universe. got a lot from this and I thought Robert brought out the best in Sean, an already lucid explainer of complex ideas. thanks for sharing.

This was an amazing conversation that showed the value of having a knowledgeable interviewer who takes pride in the questions as well as in letting the interviewee “do their thing”.

Dear Prof. Carroll seems very happy with his new position and I am happy for him.

Sean is such a wonderful teacher. Thanks for this!!

How fortunate to have ready access to the golden part of the Internet explosion - continuing education, and from the likes of Robert Lawrence Kuhn and Sean Carroll. Robert sets up some of the best topics in Sean's latest book and then Sean is able to articulate response with such clarity and ease. An outstanding contribution to public awareness and appreciation of science, the best way to cultivate the awe that comes from a better understanding of the universe.

Sean Carroll is one of, if not *the* best physicist of our time!

🙏 i am Thai,just started to watch your channel.i am still poor in English.However i 'm very lucky to be able to learn up date the most wonderful modern knowledge Quantum physics from this channel and can practice my English in advance too. Thanks so much ,keep on this so excellent human beings benefits work.🌅🌧️🌿🌎🌌👍🥰🥰🥰🥰🥰

Sean Carroll leaves me feeling brilliant!

I’ve always liked the way that Carroll takes time to learn how to correctly pronounce the names of European scientists, the ones from history.😊

This was so well done. Thank you both!

Sean Carroll such a great person and a hell of scientists. Thank you so much to both you such a compelling interview.

I'm definitely a fan of Sean Carroll! I'll be buying his book. I'm guessing he's going to be making the rounds since it's coming out. Hope he gets an appearance on one of the late night talk shows!

one my favorite things about Sean is whenever someone asks if something really IS such and such way, he always rephrases and says "it's a useful way of thinking about it." cautiously avoiding the arrogance of saying there's anything we know about the universe that is absolutely objectively certain for any possible species at any possible time to be fundamental with no underlying phenomena. all additional data confirmed by experiment is only getting closer and closer to truth (had to go for the pun) without ever absolutely arriving there. spoken like a true scientist!

Two of my favorite speakers, Robert and Sean, and one of my most favorite subjects. I enjoyed the talk. I just ordered the book. Looking forward to reading it.

Absolutely astounded here!!! Mr Lawrence, you never fail. I imagine I am not alone in actually taking you for granted old chap. You not only ask the most fundamental questions ever fathomed by mankind...but meticulously position your interviewee with a platform to respond to the Layman like myself....and boy, Mr Carrol so triumphantly delivers!!!! some of the most complex imaginings..... all in a bite size and wholly digestible package even a builder like yours truly can get at. I thank you both....and am buying the book 1st ting tomorrow.

love these guys! and yes, sean makes the equations fascinating and fun

I find this episode illuminating. I bought the Kindle version and I am reading it.

thank goodness he's on our side.

Sean is one of the best CTT contributors and this is a great conversation. Can't wait to read his book!

I am an Engineer and am an expert at solving equations. I get it understanding equations is a whole different ball game. Great intro I hope I can follow you two. This is already sounding really deep. Great talk thanks for posting.

Excellent interview about Sean's new book. Sounds like it's just what I need to move on to the next level. Robert, you asked some great questions. Thanks.

I'm glad to hear that physics and philosophy are being combined in some manner rather than butting heads against each other. I've always felt that both go hand in hand. One greatly compliments the other.

This is such a great video! Looking forward to reading all three books now after watching this interview.

Big up Sean, the Goat of public intellectuals 🐐

Thank you for the time you spend doing these!!!!

I'm a big fan of this guy. I recently got to meet Richard Dawkins, which was a big moment for me, and Sean Carroll is one on my list of famous skeptics I'd like to meet while I'm alive. I hope the opportunity comes to make it happen one day. If he's ever in Canada, I'll be there.

Love to see two of my intellectual heroes having a conversation.

Good for you Sean on your new position !! I wish you all the best !

I loved watching Robert obviously thrilled at the understanding this book gave him, and getting the opportunity to speak with the author. It was particularly good to see him ask about something he didn't quite understand, but once explained, it clicks "Ah, I see it!" 😊

Loving the book so far!

I've enjoyed this chat. Thank you very much.

One of your best interviews.

Thank you both!

Great interview brother!!!

Glad you came east coast come down to Virginia sometime!

good on sean to bring people more understanding this is very noble effort

Yes! I was expecting for this for a long time! Love them both.

Gratuliere Professor Dr. Carroll!

Good on Sean Carroll for including equations in his book. I think the real reason why most scientists don't include equations in their popular books is because they're actually too lazy or unable to explain the math in a manner that is comprehensible to an educated but non-expertised lay public. The result is that for the educated individual who wants more than a very superficial understanding of the math, it remains inaccessible unless they get their hands on or delve into a textbook. However, a truly talented teacher can find ways to teach the math on a more intuitive level for a wider audience

Brian Greene included equations in some of his books, which I really appreciated.

I feel so enlightened by this information. Thanks. 😀Book purchased arriving tomorrow! $20...greatest deal in the Universe.

Thanks Sean for demystifying big ideas. And thanks Robert for asking the questions we need to understand. Keenly awaiting the book on Emergence which seems to be a keyhole into "next levels" in physics, or really, into reality. Such as why do emergent properties exhibit a kind of certainty if underlying reality is uncertain and probabilistic. That's a big idea needing a big philosophical answer. Thanks

Superb - will let you know if the book matches up to it. Best in-depth channel on you tube. Cheers Dr Kuhn.

Wonderfully written book. …..and chapters within the book can be revisited.

Can't wait to read the book!

I strongly believe that either the Many Worlds Interpretation, or The Simulation Hypothesis, is the correct explanation of our lives. We either live in one of an infinite number of possible realities, or we are living in a digital simulated universe under a greater Universal Consciousness that exists outside of our perceivable "universe". For this reason, Sean Carroll (for the MWI explanation), and Tom Campbell/Jim Elvidge/Rizwan Virk (for the Simulation Hypothesis explanation), are the ONLY scientists whose talks I take seriously and never get tired of listening to.

Very interesting plus a great learning opportunity, I will be purchasing this book, thank you Sean Carroll you have a high sense of clarity that I can HEAR what you are endeavoring to explain to us that are curious to the issues of the Universe.

Hopefully there'll be future volumes that'll cover the rest of the topics that are covered in the online series.

34:28 I finally grasp the Hamiltonian at a basic level. Thank you!

Loving the equations.

What.. 3 vol… oh hell yeah!!!! Im so excited for this!!!

Thank you for the fantastic opening talk. I sometimes get scared of anti-creationist talks but I'm delighted to know that it's never a 100% conclusive topic and there is always the motion to just let others believe what they feel, see, or sense.

Robert! Great discussion. Sean is hands down and perhaps the best in the world at articulating the complexities of atomic physics and its limits compared to fields we see and experience all day every day. This topic seems to be the very "Theory of Everything" science community has been seeking. The precise use of terms to describe these ultra complex topics is a huge turning point it seems we as human society need to tackle in the academic medical, biological, social, physical, micro/nano scale and up to astronomical (JWST) science worlds.

Good talk and I liked the interesting answer to the singularity question as a moment in the future

Great job

Finally one author that is not afraid of equations :)

Gonna buy this book!

Bravo!

I second Margaret's comment. Thank you!

Wow , Max Tegmark . . . Really enjoy the way this man thinks . . . Yet another brilliant segment . Odd bless you Robert :)

Love shaun!!!!

57:22 The Eötvös experiment is my favorite null result in all of physics!

This is gonna be good

Finally equations got into a fun book 🥳

Whomever needs to hear this : you deserve someone who looks at you the way Sean looks at RLK.

I see both of those book shelves and have a great hunger to spend hours perusing them! 😍

Both brilliant minds

I wasn't aware that Robert is also a graduate of JHU, like myself. Welcome to the area, Dr. Carroll. I hope you are a fan of lacrosse...lol...Go Bluejays, indeed!!

Two of my favorite hosts combine?!? My lucky day! Id love to see Jeffery Mishlove join you both.

❤ Very good 👍🏼

Man, I love this channel "Closer to Truth." Sean, I can't help but think that the absolute only true Constant is Change. Could Change be Intropy playing in the realms of its life? Of course you might laugh at my ignorance, but aren't we all still quite in the infancy stage of knowledge?

Music to my ears... 🎼🎶🎸

Excited to read this book!

Congratulations sean! I've always appreciated seans affinity towards all world views and recognition of what assumptions science makes all while also explaining the value in what where when and why. I've always thought he was to rational and logic to be at UCLA im surprised he made it out without it changing him or selling out to propagandist.

Ballroom dancers could probably dance to Sean Carroll's speaking. He has such a distinct cadence.

I liked it. It's hard to understand for the Most of us but somehow true...

Is space (three dimensions) moving through time, i.e future? Space is past, being pulled by causation as present into time of future?

Takes the cake...

Arrow of time always remind me of Boltzman

Can someone say which was first? Energy or matter, or are they dual

Sean Carroll = Biggest charlatan in today's scientism.

I wish to see Sean Carrol and Nima Arkani Hamed in World Science Festival or in Closer to truth together.

Roger Penrose’s Road to Reality … for those middle chapters you’ll need to check out some external resources to understand

what is the matrix of metric tensor, 3x3 or 4x4 or 3x4 or other?

Magic! position and velocity accompanied by ΔT. Traffic tickets could be so much more thorough, with all those details included!

570th viewer :) LOVE YOU GUYS from Closer To Truth!!

Robert, while on the important ideas addressed in your show I don’t necessarily agree with all of your views, and more specifically those of some of your guests, in forcing me to think carefully about my own beliefs your show has been a great boon to my philosophical growth, and I suspect to many others. Among prominent thinkers I find my philosophical views align most with those expressed by Sean Carroll. While this interview, and his recent book were more about physics than philosophy I thank you very much for having him on.

37:03 "Theories Can Be Exactly Identical in their predictions but be psychologically different in how you would move beyond them" - Carroll paraphrasing Richard Feynman.

I see în a ecuation from QFT that charge is în Dirac ec an integral over local cinetical moments of quantum field. +/-charge may be some AT left or right rotation when îs masure.
