Mysteries of Modern Physics by Sean Carroll

- One of the great intellectual achievements of the twentieth century was the theory of quantum mechanics, according to which observational results can only be predicted probabilistically rather than with certainty. Yet, after decades in which the theory has been successfully used on an everyday basis, most physicists would agree that we still don’t truly understand what it means. I will talk about the source of this puzzlement, and explain why an increasing number of physicists are led to an apparently astonishing conclusion: that the world we experience is constantly branching into different versions, representing the different possible outcome of quantum measurements. This could have important consequences for quantum gravity and the emergence of spacetime.
Sean Carroll is a theoretical physicist at the California Institute of Technology, and an External Professor at the Santa Fe Institute. He is the host of the weekly Mindscape podcast. He is the author of several books, most recently Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime.
Not an "um" or an "ah". But a continuous unbroken flow of rational, logical information. What a pleasure to listen to. A lecturer of the highest order. Bravo!
Their is nothing rational about Sean Carroll. He is the poster boy for ignorance in science.
Stop it, he's not logical. 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
😂. O sancta simplicitas! Get thee to Hoffman😂
Sean says that he never gets tired of being amazed at the human imagination and at Nature's stubborn insistence on following its rules of physics. But I will never get tired of listening to Sean describe how this universe works. His enthusiasm, his clarity, and his stubborn insistence on giving a fair hearing to all sides of controversies in physics is joyful to behold. Sean refuses to remain stuck in the mud of mysteries, but instead lays out the directions we can go and patiently awaits the march of science to determine the best direction.
He reminds me of the "color commentator" at NFL football games. He doesn't just give "nuts and bolts" statistics of how many yards were gained. He tells stories of the players on and off the field and how that relates to their performance in the game. We humans may understand math, but we also understand through a good story. Sean is the master color commentator, telling stories that help us appreciate the "action on the field".

Thank you for taking the time to articulate this so well! Your view absolutely speaks for me and I think for many others too.
He is wrong , just as wrong as the claims of religion.
That`s how wrong he is.
Hubble`s discovery kills dark matter and dark energy.
This is very well written
I’m 28 years old. I’m not a student of any kind. I attended a few semesters of community college. My job has NOTHING to do with quantum mechanics, academia, or particularly difficult concepts. I’m just someone that loves to learn. Knowledge is a gift. The more you learn about existence the more beautiful it reveals itself to be. Every academic field, every culture, even different beliefs systems, allow more of the universe’s richness to come through. Instead of chasing one truth, learn to see the many truths that people use to interpret the world. You have one too.
Thank you Sean Carroll for spreading knowledge in a concise and entertaining way. You’re a cool human.
"...Instead of chasing one truth, learn to see the many truths that people use to interpret the world.""
This just
Thank god for the internet so that people like you and me -- another person with no knowledge of physics but who loves to learn - can access such amazing content as this, so easily!
This man is a gift. Truly in the tradition of Feynman. A world-class elucidator of high science.
Hear here. I see "Sean Carrol" and I click. And I watch. PS check out Joe Rogan's episode with Sean. You will not regret it.
@@paulmichaelfreedman8334 I have watched the Joe Rogan episodes with Sean Carrol many times, and learn something new everytime. Excellent.
Check out Sean's podcast- Mindscape, incredibly varied guests.
I think you need to read more about Feynman.

True, I had to watch it twice and perhaps a third time in the future, it is amazing.
Sean is a phenomenal speaker . Thank you Mr Carroll . 3:51 for those that don't need an intro
Thanks

He has that gift of speaking with a smile in his voice.
I thought the same as the first part of your comment, scroll and it's #1
I think it's "Dr."
I think Sean Carroll is such an articulate and brilliant man. If I had half this man's brain, he'd certainly want it back.
Good one👍
You had me in the first half ngl 😂

Indeed - and I've watched and listened to the best. And this man is the best!
Sean's brain is unsound. 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
I could listen to Dr. Carroll for hours. Like Brian Greene, Lawrence Krauss, and a few others I watch on a regular basis, his ability to elucidate complex phenomena is amazing.
Thinking about a comment, then looked at yours and it said exactly what I was thinking 🤔 .....Ditto
Listen long enough and you will find out how shallow these lectures are... Compilation, repetition, ego...
@Joe Chang I don’t know what you’re smoking but you might want to sit down. I love when people question the validity of science while using technologies that depend on the science they are questioning. Might want to keep your day job dude! 😳
@Joe Chang Let me guess. According to you this is all caused by a supernatural being for which you have concrete evidence of its existence. Oh, okay.
I largely prefer him over Brian Greene tbh. It's like he's is constantly trying to be "hip" and "funny" and to me it just feels incredibly awkward
I've loved listening to this man's lectures and books for the last 15 years

Always appreciate your lectures, thank you!
I came for the physics, I keep coming back to overcome my insomnia
I thought it was just me .
I tuned in to fall asleep, but I'm finding this is interesting.
Now it's harder to fall asleep.

@@douglasnordwall3482 Cool, I just did. He's a bundle of excitement! A great way to get people interested in these topics. Thanks for the tip.
My favorite for that are these fusion power lectures by Steven Cowley but I can't keep re-listening.
The quiz at the end of the lecture joke never gets old. Sean is a great orator. I am just geting into the world of Physics and am really enjoying his talks.
I absolutely love Prof. Sean Carroll's lectures!! He makes it so interesting even for laymen like myself!! He has such vast knowledge and never gets boring!! Love it
He reminds me a little bit of my physics teacher for the year I had to take in college for my biology degree. I never thought I'd find physics that interesting but I did.
I like all his lectures after he hopped left at Cambridge from my perspective.
Why are people conned by this guy? 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
Thank you for such a great presentation. Dr. Carroll can speak for 24 hours non-stop and I won't fall asleep! Particularly liked his version of explaining the QM anomalies - not by "quantizing" our conventional classical models, but ground up from a native quantum mechanical universe.
This really is as good as it gets. He knows the material and knows how to explain it.
Thanks for making these concepts so accessible to the general public. Again, another very effective presentation by Sean Carroll.

Why don't you try thinking and see Sean for the liar he is? 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
Big Thank You for the excellent presentation !
45:30 world is made of fields, not particles; matter is vibrations in quantum fields, and fields are pervasive throughout space. Particle vs field view of nature 47:00 features of entanglement; space is emergent 47:30 geometry of space and entanglement 52:00 past and present different because of entropy ; entropy increases over time 54:40 time
The explanation for complexity as a middle way between no entropy and a lot of entropy simply blowed my mind. Amazing amazing talk
One of the great communicators of our generation. I’m so glad that these have been recorded so I can share with my children.
I especially liked his interpretation of connecting Einstein's space curvature with quantum geometry versus energy and entanglement. That is the best interpretation I have witnessed of connecting Einstein's 'Classical Interpretation" of gravity with Quantum Field Theory. I have been looking for someone to describe a possibility and this one seems plausible.
Yeah. That was pretty mindblowing to me.
But will it be enough to make a theory of everything? In other talks he shows that gravity in the core theory equation is quantum and it is good enough to be accurate one large scale, just like relativity, but not in extreme cases like black holes etc.
@@martenjustrell446 czcams.com/video/KsIsXvvlr3c/video.html can you give opinion for this topic
czcams.com/video/SOWt2fBI1VI/video.html
As an engineer who has always been passionate about math and physics, I was intrigued by modern physics, despite neither relativity nor quantum mechanics were part of any course syllabus at my university. I studied these subjects on the side and found them really inspiring, I would go as far as to say that they gave me a novel perspective on life itself. That prompted me to create some online courses on Udemy on Quantum Mechanics, Quantum Field Theory, special and General Relativity. It’s not my job of course, but I love talking about these topics while using some mathematics for “intuition”.
Quantum Entangled Twisted Tubules:
When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else.
In other words, you are a kid who failed high school. :-)
@@lepidoptera9337 I was pretty good actually !
@@math.physics That's what all the failed kids say on the internet. In any case, that's between you and your school. :-)
@@lepidoptera9337 I don't think a "failed kid" can teach QFT, GR or other subjects :).
Really interesting talk. Hope we get more such uploads from you.
Sean is really a great educator. He is able to illustrate very complex subject matter in a very intuitive and passionate manner. I was really never good a physics in high school esp. when it came to the math and the corresponding formulas. Yet, I feel I have gained some basic understanding of the theories presented here and in other lectures by Carroll and folks like Brian Cox, Richard Feynman and others. I am very much into the arts and I find that the arts and the sciences can inform and inspire each other. Connecting it to the real world. It reminds me of the great and beautiful gothic cathedrals that inspire but were only made possible by understanding physics.
He's not even following science. 1LofT states that energy can't be created or destroyed, it can't happen naturally. One aspect of the 2LofT shows that the universe is winding down, usable energy is becoming less usable. Creation had to be done supernaturally at some point.
I’ve got forced to be all ears by his excellence of knowledge and skill of storytelling.
Excellent presentation! For a novice person like me, this was an eye opener!! Bravo!!!
This man has given me so much insight into how this world is and came to be (after the big bang) and why it is the way it is - and I have never taken a physics class nor have I taken a higher education math class - he is such a joy to listen to and my moments of understanding astound me!
It is an amazing speech worth watching no matter if you love physics or you are not really interested in it. In my opinion everyone would enjoy this lecture and start to think about some incredibly mysterious things around us.
I love listening to Sean Carrol. ❤

The content is as old as Sean himself. Easy money for him. But Darwin College is feeling great ... only because of his name/fame. Fine presentation though.
Yes... I enjoy listening to him too.. right?
@@ericgraham8150 I agree. But it's the same old story over and over again. It seems there is nothing new in physics to tell about. Going deeper means going more mathematical (and further from reality). There's no audience for that ... even at Darwin College! ;-) And that means there's no presentation and money for Sean.
Once saw him in a hotel, introduced myself and got to compliment him about his youtube lectures. Probably was a few weeks before this lecture.
One of the best I came across...... Outstanding.
Always enjoy Professor Carroll lectures.
Wow, great lecture! I've devoted nearly half my life to studying physics, but I never really thought of it in this way. Sean both explains, at least in part, many of the biggest mysteries of physics and points to new ones. Great job!

Gravity should be updated as such: 13.3321 m/s^2 and the general theory of relativity should be this as a LAW : ((G*2073)R)) --- --- --- That is why we struggle with physics because we believe in Einstein's postulations of physics as such: ( E=m*v*3000) is the Law of Special Relativity.

I am a complete dunce when it comes to physics but this man brilliantly elucidates and makes genuinely exciting every aspect of the subject in a way that even I can not only understand but also enjoy. Never an umm or an ahh in his monologue his voice holds the attention in the most astonishing way. Ten out of ten! Just riveting!
this is an Incredible Documentary and i could listen to Sean Carroll for hours, he explains physics in such a way that even if you don't know anything about it '' you will understand what he is saying, *
He sets up Schroedinger’s cat experiment beautifully and builds up the explanation to......multiple worlds hypothesis, when you think about it it’s not any more satisfying, now we have neatly infinite copies of the entire universe to accommodate all the possible quantum events. That’s a lot of stuff, I’m not sure this is correct, I’d like to trust him but I’m not sure he advanced the argument very much.
No cats were harmed in the making of this presentation.

I felt the same way!
thanks, Sean, for the splendid lecture on the basic problems of modern physics. surely, understanding of life is fundamentally inportant and can give us a key for the better understanding of quantum mechanics and of our physical reality as a whole (as well as of ourselves in this reality, i guess))
He's incredible. Spoke engagingly for an hour with barely a glance at notes. The lady introducing him, however, could scarcely utter a syllable unless her head was lowered and fixed onto her notes.
Carroll breaking it down in understandable consumable chunks. Fantastic.
"It's always good to do experiments to see what happens, so let's do this one..." And then someone turns the lights off.

Isn't there some comic or comedian that he looks and sounds like?? Now I can't remember the name, but I'm sure that's who he reminds me of.
Yep, thought the same. John Mulaney.
It's now much more clear to me how consiousness is the biggest key factor on every topic that he covered here.
His composition and presentation put it right in front of your face on each point, making consiousness the most obvious missing element to every problem, without coloring it in for you like so many other do.
Terrific presentation!
very great lecture Mr. Carroll!
Finally, a smidgeon of comprehension comes my way. Excellent lecture.
I think the answer to the quantum mystery is just the idea of quantification itself
The universe does not have exact numbers to correspond to it what is rather always in a state of flux
An example would be saying that I'm 6 ft tall. It's just an approximation. Someone's exact height is always changing but we give an approximate estimate
This is the same with all quantification. It's only accurate within the margin of error
Height weight, any mathematical description of a system is just an approximation
In reality the electron is distributed in a cloud and always will be
But when we give mathematical descriptions of a system we're basically giving an approximation that has some utility
Therefore all the terms like superposition wave function duality, they're all just terms to give some Precision to something that'll always be Beyond quantification
It's like the shape of the Earth you can say it's a sphere or an oblong spheroid and that is more accurate than saying it's flat
But the utility is always based on a relative system.
in reality the shape of the earth is always changing slightly
Anyway can someone hit me back and see how we can get these ideas being discussed by physicists like Sean Carroll
I think what I'm saying here is a more basic idea then the many-worlds
In reality many worlds is just a an attempt to give Precision to the universe the same way we give Precision to the shape of the Earth. But in reality such linguistic terms will never capture the Nuance nature of reality. I think it's more fundamental to just say that quantification will always be accurate within the margin of error and that the actuality of reality can never be precisely described in any way that is true for all Observers.
So again the fundamental mystery or Indescribable nature is due to an attempt to quantify what is beyond quantification in an ultimate sense!

@@ingathrise Math works well to understand QM as well the cosmos but it does not look that they are in the right truck or right frame, if every thing is made of light then matter must to be acomodated as the rainbow shows, even light follows atomic waight why not matter?, Einstein, Hubble as well Neuton might be right at the yellow level that we are but as soon we look out to another level they are out of the game because they must to recalibrate to that level. - In quantum mecanics light aplies cause the photon is still light even if it is in the form of a cloud still is light and cant be at all places cause the north are gaseous and south are rocky ones same as our solar system that the inside circle are made by the 4 rocky planets and the gaseous are made by the 4 gaseous ones, the sun is the neutral part as well is the bottom of the system cause we all go in levels even stars. - I do have my channel based in colors as the rainbow based in a Mayan Callender as well a DNA picture.

sorry, the multiverse only has all the possible superpositions, not every superposition!
Sean is a great exemple of an open minded scientist, it is very nice to see.
Krauss or Neil Degrasse Tyson on the other hand, are the perfect examples of a close minded scientists, almost religious in a sense. If he's asked a question he doesn't know the answer, he will tell you : Look, I can measure the phenomena, if that is not enough for you, you can stay here playing with your '' Whys '', while me and my colleagues continue to go forward. He will then look at you with the most ... arrogant face in the world.
Which to me is unnaceptable, in the scientific world. So I totally believe Sean when he says that the scientist that was asking questions was ''gently'' tossed away. Sry for my bad english.
I totally agree with you. A lot of famous science personalities will quickly say, “that’s not my field, go somewhere else for that.” Yet, science in general has colonized other domains of knowledge. Science is the new cosmology and philosophy. The scope of science is accurate but limited, you can’t encapsulate the world with just science; nonetheless, they keep trying.
Very well explained, thank you.
Fantastic lecture!

Thank you Darwin College for this excellent upload, with Dr. Sean Carroll.
@Bertrand de Born WOW! Somebody deeply hurted you to make you so angry....but you and some others are the MEN who found out the TRUTH about modern physics....LOL.
I totally agree with Joe Gelman below. Sean Carrol is brilliant and inspiring teacher exactly in the tradition of the Great Richard Feynman in whose chair Prof Carroll actually sits both metaphorically and literally as he often points out at the beginnings of his talks. I have some his books in audible format simply because I like the sound of his voice. His proof that Death really is the end (see the youTube video) inspires one to live this one to the full as its the only one you'll get. Of course, if we are simply running as simulations in our own future descendents' super-computers then let's hope no-one switches the power off which would amount to the same thing.
Great lecture and summary.
THAT was a fantastic lecture. I only WISH when i did my degree they talked about entropy as information - when i realised that, it kinda clicked! And that when he jokes about "i swiped my arm because the glass was going to fall", thinking about entanglement first, intuitively is backwards, since our whole life experience is centred around us, it was insightful. Great lecture!
gepisar, forgive me for pointing out but "centred around" something/anything is a meaningless construction.
@@ccahill2322 great! We take what meaning we can.
* nice Mitch Hedberg reference. My man!
It is not just that this guy is a great scientist. He is also lots of fun to watch.
What a refreshing lecture!!!
"Nearby is just, a colourful way of talking about, the amount of entanglement between abstract quantum degrees of freedom." Sean Carroll
*of empty space!
You know, the original "Freedom's just another word for nothing left to lose" still makes a better lyric.
This may be profound. It is easier to move through time than space. So "nearby" is preferred. The fastest you can go through space is 45 degrees on reference diagram(speed of light). But 90 degrees of range is available in the Time direction (2x45). SC knows Relativity, so i wonder what implications he may be making?
I love listening to his lectures. Such a brilliant man. Judging by his choise of suit and tie he clearly aims at maintaining a low entropy state in style for much longer than Einstein.
One could argue though, by viewing tieknots as a self avoiding random walk on a triangular lattice (see www.tcm.phy.cam.ac.uk/~tmf20/TIES/PAPERS/paper_nature.pdf), that a state of even lower entropy could have been achieved by tying the tie into a "Oriental" style tieknot (a tie knot wich requires only four moves: left, right, center, tie), instead of what looks to be a (very stylish) "Half-Windsor" (requiring seven moves: left, right, center, left, right, center, tie).
On the other hand, a Half-Windsor looks tidier, so that may make the Sean Carroll system as a whole at least appear less entropic :P
@@impactguide I like that your joke links to a nature paper
I still feel it is absolutely amazing that all physics is is a means to put a consistent language around and understand/predict the depth and breadth of our universe at both the macro and micro level
But what gets me is that whether we understand these or not...they are...and when we cease to be, they will live on
I have read that Newton also was troubled by his theory's "action at a distance". He kept his discomfort to himself, because he, like others of his day, did not believe in action at a distance in physics. In this regard, he did not differ from Einstein whose Relativity did away with action at a distance. I find that Newton was, in this regard, much further ahead of his time than all other physicists until Einstein, to whom he might have said, "You know, I had been thinking along the same lines! I got as far as calculus, but I had not applied it to the geometry of Riemannian 4-dimensional spaces as you did, because Riemann had not yet been born in my day; but I knew something was wrong"
"...a whole nother talk..."
My socks are also in superposition (each of them is both left and right at the same time) until I put them on)))
Actually that's brilliant
😌
Maldacena conjectured that the whole universe is QC function evolving from a single wave function. Phase transition of non-life matter to life and consciousness is also a QC function. We just don't know the self-error correcting algorithm of QC function that eliminates randomness/chance (fine tuning of the parameter space) to achieve probability one state.
It's good seeing Sean finally coming into his own skin and accepting the fact that he is responsible for enticing the next generation. Thanks Sean! 💪😎🇺🇲
Atoms are like Toy Story's characters, when nobody's looking they have their own life, when somebody looks they stop.
ANDY'S COMING!
Or like that ghost in the Super Mario games
That's a good explanation of the universe and beyond!
You just perfectly described my ding dong.
Ha!
