The challenge to a theoretical physicist pushing beyond our best current theories is that there are too many ways to go. What parts of the existing paradigm do you keep, which do you discard, and why make those choices? Among today’s theorists, Lee Smolin is unusually reflective about what principles should guide us in the construction of new theories. And he is happy to suggest radical revisions to well-established ideas, in areas from the nature of time to the workings of quantum mechanics. We talk about time, the universe, the role of philosophy, a new picture of spacetime, and the future of physics.
Lee Smolin received his Ph.D. in physics from Harvard University. He is currently on the faculty of the Perimeter Institute in Waterloo, Canada, where he was a founding member. Among his awards are the Majorana Prize, the Klopsteg Memorial Award, and the Buchalter Cosmology Prize. He is the author of several books, most recently Einstein’s Unfinished Revolution: The Search for What Lies Beyond the Quantum.

Lee Smolin? This is the fastest I've ever clicked on a new Mindscape episode.

Hey! You really think you are the only one?😃
Indeed.
Lee Smolin is the hidden treasure of theoretical physics.
Lee "The Legend " Smolin ☘💞☘
I like this 80's photo of Lee chillin' in his fleece
I got you. Lol!
I love Smolin so much, such a humble character and brave enough to own how much heart they put into their work. I’m probably not going to become a fundamental physicist any time soon but I’m glad to see people like Sean and Lee in the field who have the same intrinsic dedication to learning, truth and understanding as I do.
Ditto my dude 👍
The beauty here is EXACTLY what Mr Carroll says right from the get go...both are complete different in their philosophy concerning Science...that's exactly why I wanted this conversation.
I own literally about all of their books and made of course my own conclusions mixed with many other sources that inspire...thanks again for this.
Thanks Sean at last you pick up Lee. He is truly one of the living sage of this century... I feel admired of him very much since my first encounter with him in 2015.
I love Lee Smolin, he's an extremely pleasant person to listen to.
Lee is great. He's a deep thinker. I stated about him on another channel: "Lee is honest with himself and honest with everyone else." We need more of that.
His over the top hand gestures are a bit weird though, lol!
Unfortunately I found it rather unpleasant to listen to. I know Sean cares about audio quality, to the extent that he sends his guests a good microphone to use, but I guess Lee chose not to use it.
I enjoy all of your episodes, but the ones with your fellow Physicists are always amazing.
It creates such a great and accessible fly on the wall experience of wonderful conversations. Differing experts are always welcome, but you're right: these feel so special. The density of expertise while still having different points of view in healthy, productive ways is so inspiring. Future isn't so bad sometimes.
I've read "Something Deeply Hidden" and "Time Reborn" : we're so lucky to have these two physicist discuss their views extensively, right in front of us. They are equally extraordinarily clear in their teaching of contemporary physics. This was a great (and respectful) high level conversation on the issues. Thanks for this !
Sean, thank you for inviting people like Lee on, even if you have different perspectives
Thankyou, thankyou, thankyou... what a treat, as ever🥰🤯
Lee Smolin on Mindscape... it's about time AND it's about time...😉
Love having the differing perspectives and the clarification questions. We need to get Lee a better mic/puter/internet he has lots of great things to offer :)
i heard Sean usually sends out a good mic to people he does an extended interview with.... maybe this time the offer was rejected or the mic wasn't used properly because the audio is a little bit lacking in quality ...but you get used to it and it's perfectly audible anyway
@@robertnewhart3547 That's not what your mom says.
Two of my absolute favorite physicists! So happy to hear more from Lee Smolin!! And as always Sean is an excellent host, really in a league of his own.
fr
I few days ago I was thinking "Lee Smolin on Mindscape... Now that would be a treat!!"
Wilczek on Lex yesterday now this today, glad I haven't been busy.
Dude, you should wish more often. Can you wish for fusion generators and to end world hunger ?
Love listening to Lee Smolin so much. He feels to me from this immense distance like a genuinely decent human being, a true philosopher in the deepest sense.
Thank you, mr. Carroll, for inviting such a great scientist in your podcast. I also do feel strongly that flow of time is fundamental and irreducible to something else.
Hot digs. I wasn't sure that Smolin was going to have an episode. Two thumbs up Dr. Carroll.
22:34 They talk about the contention. 😮
Thank you , for this episode. Dr. Carroll your ability to extract difficult topics and make them clear is extraordinary. Dr. Smolin arguments are sometimes difficult for me to grasp. Bringing out clarity and simplicity is not only essential but worth respecting in today's world.
Sean, Is it possible to get Nima ? Please 🙏🏻
I m always wondering that, I would love to hear Nima ‘s ideas.
Why
This is now my favorite channel. Thank you so much Sean Carrol for all the great work you do, and for making this pandemic easier to get through for many of us.
Literally stopped listening to one of Smolin's books to listen to this. Was not disappointed. I love the physics Mindscape episodes.
Finally, someone who can actually challenge Sean's Eternalism! I bet most people will think Smolin is just being obscure by citing Charles S. Peirce, but some will be able to understand it: Peirce's semiotics is not limited to Mind, as Sean would have you think, and it changes completely the understanding of Physics and Quantum Mechanics. If you have an opinion about this without having read Peirce, you don't have a good opinion. Do yourself a favor, read it. It'll take time, but most of it is free online. Cheers.
Always a luxury listening to Lee.
I don't agree with everything Smolin says, but his mind is indispensable to the philosophy of fundamental physics today.
A lovely blend of phylosophy and physics, history and futurism, of indulging anechdotes and moving things along. All in all an elegantly crafted production. Thanks.
Lee you are one of my favorite physics authors, and I want to think you for the time you're spending bringing the topics to the masses. Every time I end up recommending one of your books I also end up discussing it after, too. You must like Kurt Gödel and Julian Barbour, too.
ty again
Fantastic guest, great content. Thanks a lot Sean Carroll👍
An hour and a half gone in the blink of an eye . Loved every minute , even though its quite disappointing to think the more you enjoy something the quicker time seems to go . Great talk chaps . keeping the enlightenment moving forwards is a worthwhile endeavour
This podcast barely touched on Dr Smolin's bigger ideas so I highly recommend his latest book, "Einstein's Unfinished Revolution - The Search for What Lies Beyond the Quantum".
He presents a very ambitious approach to establish a fresh reset of understanding the Universe by starting with a set of 5 principles on which to build upon for modeling and possible new laws of physics in the finals chapters.
Just what I needed! Some new Lee Smolin conversation. My own work is very much in line with his, and I can always use some nudges to think a little more weirdly about my models (which is basically Pascal's triangle with all possible combinations of matter/contraction/stability and energy/expansion/change evolving ever more complex patterns that are each their own timeline branching and recombining in a network of all possible paths through reality.) I've been sick for a while (probably long Covid) and haven't been able to work, so I'm hoping this inspires me to push my malfunctioning brain in the right direction. I'll let you know when I'm done listening. Thanks!
Woohoooooo
Get the tea ready!
A fine new episode, thank you!
Loved this episode Sean; maybe the best interview with Lee Smolin! Obviously Lee is great; but I was also very impressed by your interaction with him.
I've been begging for this to happen via nerve wrecking comments...danke Mr Carroll.
Great to listen to Lee. Also a word to a most considerate host.
Another excellent discussion!
Thank you so much!
Pls, also include the time stamp in the description. A great talk as usual.
Please bring Professor Witten
Written another absolute loon, genius. You seen his lectures? Mental. The only physicist to the fields?
Just listened to Lee on Brian Keating pod cast,,,looking forward to this one too . Good choice Sean. 👍😎😷
Lee Smolin ...... It's great, I'm sure.
Thanks for that, professor Carroll.
Lee Smolin on Mindscape: excited !
Hearing the audio quality: desapointed.
There is a transcript of this podcast available at the link in Sean's description so you can read it.
Disappointed*
Great discussion, I waited until I had the time to listen to this in it’s entirety. Nina would be great and so would a 3 way discussion with Carlo as mentioned by Lee.
I thought I was going to like this episode a lot more than I did. The sound quality wasn't so great on Lee's end. Plus, Lee was hard to follow. I've listened to multiple interviews and symposiums with Lee so I am familiar with how he speaks but for some reason I just couldn't follow him. When I could hear him it felt like he was just talking with one enormous run on sentence. Idk he's still a giant in the field of physics and I loved his book on time. I guess I'm just sad this episode didn't live up to my expectations. Ah well. Can't wait for the next one Sean! Thank you! P.S any chance you can get Hofstadter on? Guy is like a rare Pokémon. He never does any podcasts!
Susskind, Penrose, Tegmark and now Smolin ... this place is heating up from way too much intellect.
Because it's on UA-cam it should balance out.
Did you just read _my list_ over my shoulder?
Well, Susskind is an asshat.
@@FelixBat lol, exactly. Didn't he get that qualification/certificate from a cracker jack's box?
Oh boy, what a great combo.
A treat to finally Sean and Lee Smolin discuss Many Worlds. Can we get a real discussion on this though? Stopping the debate at non-locality
... I think Sean you were too polite.
Hi everyone,
Has Sean or any other was explaining why Mindscape is devoid of video?
The reason why time is fundamental is because we (and all matter) is stuck in the present based on the fact that two objects cannot occupy the same space. All spaces in the past as well as the future are filled.
I am also so much behind the background independence, too... I've spent hours explaining it and also _arguing_ against background/cosmic canvas. People will get vicious about it, and how it damns absolute time. Saying that time isn't real often gets me a virulently angry response like I screamed "eff your God" in a church... lmfao
It's a bummer the sound quality wasn't amazing on this, it makes it a lot harder to focus.
Just getting ready to say the same thing. Shame.
It seems Lee didn't use the complimentary mic.
Yeah, I'm having difficulty following what Lee is saying at times. Sean's mic sounds just fine.
@@timc7035 Sean Carroll is fine but Smolin sounds a bit like that in real life too. He is getting old too so he may be getting a bit of a resting tremor. He is very clever guy, he understood GR at 15/16. Nuts
I too was frustrated so I went to the link in Sean's description to read the transcript of this podcast for the words which I could not hear clearly.
What do u think about Maldacena work?
Is it possible to include the existing transcript as subtitles? That would be very helpful!
I thought You would invite MR Smolin after his criticism of your many world theory. 🙂🙂🙂👍
1:04:00 Lee Smolin's over arching picture sounds similar to Stephen Wolfram's automaton ideas. The universe at bottom is made up of cascading discrete events. Thats basically the standard cell like automaton view, each interacting cell is an event and the causal sequence is time.
Bernardo Kastrup any time soon?
Any chance to bring Alan Wallace on the Podcast? Lets bring some Eastern perspective to understand Nature of Reality
What they don't bother to tell you, is that if you for instance examine "Motion" to determine what it is and what it is that is required to make motion possible, you will in almost no time at all discover the Einstein Special Relativity(SR) phenomena, and you will independently derive the SR mathematical equations all on your own, and do so in mere minutes as well. This includes deriving the Lorentz transformation equations. It is so easy to do. I managed to do it even though I am a high school dropout as the result of having a nasty head injury at the age of ten, an injury that ruined my ability to store long term memories up to the normal scale. So, due to the effects of the head injury, my teachers classified me as being the dumbest student in the class over the many years. So you have to understand that even the so called "Dumbest Student", can discover SR and derive the SR equations.
I heard Lee was in favor of decoupling space and time. I am in favor of this approach to quantize time and space. Quantize gravity would be an imbalance because space and time being decoupled would be one to one. So instead of quantizing gravity we should quantize speed. If you quantize speed this is putting space-time on a one to one ratio. Also quantizing speed implies that there is a slower speed that is non-zero they quantum speed. And if you subtract a quantum speed from the speed of light you would be calculating the fastest speed for an object with mass. I call it the virtual speed of light.
Please make a program with Douglas Hofstadter! :)
I read one of Smolin's books and found it very clear. I'm surprised to find him rather opaque in discussion. Maybe it's just in comparison to Sean, who is such a good story teller.
Yea, he’s not a great speaker.
"They see Lee Smolin; they Lovin, tryna catch me ridin dirtyyyyyy
The Arrow of Energy - "Time taken in stocking energy to build an energy system, adding to it the time taken building the system will always be longer than the entire useful lifetime of the system.
No energy system can produce sum useful energy in excess of the total energy put into constructing it.
This universal truth applies to all energy systems.
Energy, like time, flows from past to future".
(Proposed, 2017).
Can't wait to find out why the A theory is true and the universe has a cause of its existence!
Cool! But why is Lee talking through a modem connection?
I wonder if a Gödelian cylindrical model could be tweaked to fit a hypertorroidal type universe... timeless, but not from out perspective day to day.
When do you get John Stunja aka 'Quantum Eraser' as a guest? He's an odd fellow
Audio quality on Mr. Smolin's side is well... subpar. Quite difficult to understand everything he says.
Lee Smolin search for the cryptographic universe.
All your thoughts about physics are good and probably correct( based on what I know).
As to your question of the main paradigm from which all physics laws emerge i can make a suggestion:
All laws i know of are written in forms of 1functions. 2operator theory. 3numbers.. must be computable by a timespace algorithm( always observed to be true,,). So. ..4must be a infinite basis 5spectras in a medium light waves. Number theory is the way hence 5must relate to the way the roots (values, real or complex)
of the Riemann Zeta Functions compute. Ie primes and what they mean.(the integrals. Or spectral laws) .
The zeta function is a 'suspect ' because computer people know these forms and root functions are eigenvalues of some new Hilbert operators in quantum physics.
Figure it out.
Physics is incredible 'cause it's the king of all science and knowledge
And I still prefer Evolutionary theory ( Life sciences )...but in these days you better explore all the fields. But Particle Physics is the beginning...and the end.
This guy is far out, Carroll keeps him on track but his mind is just all over areas and depth is just nuts. I think Carroll sometimes thinks 'Wtf!' What chance do I have!?
Agreed. Tenure is a powerful drug
the upmost respect for all scientists as I would not be here other wise, “I have not failed 10,000 times. I have not failed once. I have succeeded in proving that those 10,000 ways will not work."
"I'm going to bite my tongue or we'll end up going down a raabbit hole", so polite world class cage fight from 2 champs indeed
Clash of the titans!!!!
Sound quality bad
Oh, I was so looking forward to this, but the sound quality is unfortunately unbearable.
To say that there are properties of conscience in the fundamental particles is like saying there are properties of chess or baseball or literature in fundamental particles.
Also, there already are scientists studying consciousness, they are the biologists and neuroscientists.
I wish Lee Smolin would buy a better microphone and/or audio interface. It's the same with every video he's on. By the time I've deciphered the words I don't have enough brain power left to think about what they mean.
"A model is something that can be defined by a small list of rules." Wolfram has conjectured that there exist 4 or 5 simple rules that yield empirically satisfactory approximations to quantum field theory and general relativity theory. Are there 3 fundamental concepts of time: Newtonian time, Einsteinian time, and Wolframian time? I say Milgrom is the Kepler of contemporary cosmology - on the basis of overwhelming empirical evidence. Google "kroupa milgrom". Think about Steven Weinberg's research. Gravitational energy is conserved if and only every graviton has spin 2. However, if gravitational energy were conserved, then Wolfram's cosmological automaton would not have a simple timing mechanism. Consider 2 hypothesis: (1) Dark matter is an effect caused by gravitons that have spin > 2. (2) Dark energy is an effect caused by gravitons that have spin < 2. How do physicists know that the 2 preceding hypotheses are wrong? Google "fredkin milgrom".
So who's here after Lex Friedman called the event one year ago? :)
Why did the universe start 13 something billion years ago, and not 10 minutes later?
Honey! I need to go to the bathroom, and then go pick up some milk... and... eeh something else for the next 90 minutes.
It's hard for me to hear bad accent with poor connection!
Hi Mr. Sean realy like your work, but presencial vídeo its much better, all the best.
You would get so many more views if you just added video. And it's not like it takes any extra effort.
Why does Lee Smolin want to search for non-locality, when Einstein since hundred years explains that photons in their velosity do not have time nor space? Photons live in one moment of time and all the distant space they traverse is just a local point for them. There you have it in the theory since more than hundred years : non-locality
Time is the best teacher, unfortunately, it kills al of its students....
That was great. Lee is an amazing man
What's is the excuse for the bad audio quality? Both gentlemen are authors who give interviews as part of their book tours, both have done Zoom/Skype interviews during the Pandemic, both are invested in what they are trying to communicate, both are experienced speakers.
If you have the time for extended interviews, you have the time to prepare and check BEFORE subjecting us to this.
Do you complain about free gifts?
@@DontKnowHowToSayNo and this gift was worthwhile to listen to but I had to find Sean's transcript in order to read what I wasn't able to hear.
Sean Carroll and Lee Smolin? Sweet. Not having to watch Lee Smolin gesticulate? Even sweeter.

The Universe did not "choose" any laws. *OFF!*
