- "Quantum Worlds & the Emergence of Spacetime"
Caltech research professor, theoretical physicist, accomplished author & podcaster Sean Carroll will talk quantum physics and the validity of the many-worlds interpretation (MWI) of quantum mechanics by discussing some of the themes in in his new book, “Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime”.
Before jumping into the MWI, Sean Carroll provides an approachable introduction to quantum physics. He discusses the history of the field, notable theories and their limitations, what questions remain unanswered and what the world may look like if the MWI is proven true.
More information about Sean, his research, publications, or other projects can be found at his website: www.preposterousuniverse.com/

One of physics best speakers these days. So clear and direct. More people need to be exposed to these types of topics and Sean Carroll provides a great place for minds of all intellect to join in and learn more about the world around us.
Slipperyfish it’s the fact he knows what to say. There’s no umm’s or pauses while he tries to remember his lines. I like that, it just flows into your memory and stays there.
@@minimead368 ive never seen him pause to think in any video. Its just a constant stream of info
@@boughtinerror He clearly knows his stuff, ok, plus he talks about this stuff all the time, ok, so a lot of that is pretty much routine, ok?

One of my favorite thinkers in the world. Few people of such vast intelligence are able to explain very abstract things so lucidly and understandably.

@@BradWatsonMiami Religion, ALL religion is self-deluding nonsense. And you need to go live where the nuts hunt the squirrels.
People like Sean Carroll made me interested in Quantun Mechanics. The way he explain everything makes you love all the stuff about physics. His books are great and everytime i re-read them i learn something new.
slow learner?
@UCUZMI2O8DllphiwEcqk6Asw I’m guessing your trying to predict how he thinks, well your prediction sucks and you sound dumb
Carroll brings to the masses an understanding of QM that allows you, the non-physicist, (but perhaps a philosopher) to better think about reality from the micro- to the macro-realm and that Emergence is the operative term. Emergence addresses the transition from the fundamentals up to and including spacetime. Carroll is a master communicator whether you accept what is rather easily understood from hearing or reading from him or not.
@Via hahaha epic!
Sean Carroll's hair is in superposition between clean cut and wild theoretical physicist
I legit laughed out loud from this. Great fucking joke!
The lock of hair flipped over his ear is a classic wave function - otherwise known as the Schrodinger hairdoo.
I think he is both letting his hair grow and dyeing it. IMO, he should cease doing both.
@@JoeLeonardo No, its a very limited example of a joke with an even greater minority of people to appreciate its vague and vacuous application of comedy.
If it's vacuous, how can it be vague?
Hugh Everett even visited Copenhagen in order to meet with Niels Bohr, the "father" of the Copenhagen interpretation of quantum mechanics. The visit was a disaster! Everett's idea that the universe is describable in objectively existing universal wave function (which does not "collapse") was simply a heresy to Bohr and the others at Copenhagen. The conceptual gulf between their positions was too wide to allow any consensus. Léon Rosenfeld, one of Bohr's devotees, even described Everett as "undescribably [...] stupid [who] could not understand the simplest things in quantum mechanics". Everett later described this experience as "hell...doomed from the beginning."
The first half was an exceptionally good summary of the eave-particle dilemma. Really enjoyed that.
Amazing! This is the best explanation of a concept! He always repeated the same sentences in different talks, but only now I finally got it! Over time he perfected the way to explain it to other people!
He took the time this time.
Sean Carroll is my favorite living physicist, ainec. I can not wait to get my copy of his latest book ‘Something Deeply Hidden’!
From my view on the sideline as an amateur philosopher of science, I believe Professor Carroll is near the goal line, and will make it into the endzone. What a great day it will be to finally spike that quantum football!
This guy's the best. Loving the videos and loving the book, whose every chapter I have to read at least twicel

Sean is a Real Revolution, an observer with unmatched potential and traits, a teacher beyond ordinary human potential who justifies his teaching traits with exact knowledge or research work original to himself after testing it thoroughly and above all he is open to feedbacks to rectify errors as well as stay humble with appreciations.
He just Rocks Physical science.
Thank you Sean ! for all your research in scientific domain.
Lots of appreciation for your originality.

Sean Carroll provides the best explanation of quantum mechanics that I have seen to date. He gives a quantum mechanical explanation of curved space-time and vacuum energy. He idea of not attempting to quantize gravity but rather to start with the Schrödinger equation and deriving quantum gravity is unique, as far as I know. I especially like the fact that he's a devotee of Hugh Everett's Many-Worlds interpretation of quantum mechanics. I'm a member of a book club that will be reading his book "Quantum Worlds and the Emergence of Spacetime."
Very much liked the final section where Sean suggests an approach which brings together entanglement, quantum field theory and gravity. I'm really looking forward to theoretical and practical developments with this idea.
To hell with emergent gravity. The encased microphone in a foam cube is the most brilliant thing I have seen in a long time.
reduce that to just the foam cube.....drop the mic!!!!
What was your previous encounter with brilliance?
14 minutes in and my admiration for this guy has increased dramatically. Why haven't I seen this before. It strikes me as the most honest and articulate description of the subject (for the average guy) I've come across. Show this to your physics class.
Amazing talk.
Again.
How is this man so consistently mind-blowingly well-articulated?
_...what am I doing with my life?_
I absolutely love Sean Carroll. He can explain very difficult concepts in laymen's terms which is very difficult.
This talk explains the anomolies in the double slit experiment in the clearest terms yet. Great talk.
The very best video I have seen on this topic. I'm merely a "shade tree" scientist these days (ex-electrical engineer) but this makes(mostly!) a lot of sense. I was fortunate in that I had many great profs but very few were communicators of this caliber.
Absolutely fascinating talk! Thanks for sharing!
Heisenberg, Schrodinger and Ohm are in a car
They get pulled over. Heisenberg is driving and the cop asks him "Do you know how fast you were going?"
"No, but I know exactly where I am" Heisenberg replies.
The cop says "You were doing 55 in a 35."
Heisenberg throws up his hands and shouts "Great! Now I'm lost!"
The cop thinks this is suspicious and orders him to pop open the trunk. He checks it out and says "Do you know you have a dead cat back here?"
"We do now, asshole!" shouts Schrodinger.
The cop moves to arrest them. Ohm resists.
Alberto Santos 👏
schrödinger part got me good hahah
the opening part of this joke is in the book. Thanks for sharing the whole thing!
Excellent presentation. I've always thought the "many worlds" interpretation was a cop out but Sean's explanation here has opened my mind to this. Just bought his book. Also, I always felt that Einstein was right when he said that QT's Copenhagen interpretation cannot be a true desription of reality. That whole particle / wave duopoly message and "just accept that's the way it is" always seemed daft to me but I've just assumed that these physicists know what they are talking about so who am I to judge?
Try reading The Mathematical Universe by Max Tegmark (MIT) on the multiverse
Many worlds is by far the most logical explanation.
'Something deeply hidden'....is excellent attempt towards closer to reality (Truth)... presentation by Dr Sean Carroll is really beautiful.... thanks 🙏
Thanks for this talk. It's great you show the speaker 99% of the time because we would totally not know what he looks like otherwise. On the oth we can always get access to his slides easily and there is nothing special about one slide from the other. I just love watching a speaker speak.
I really liked this talk. Several times I thought "Of Course!" - the idea of having only the Universal Wavefunction and deriving from that the rest of the world, including gravity, is such a beautifully simple/elegant theory. Thank you!
Wow, he is such a communicator ! Respects !

This was awesome thank you so much for this great presentation
Sean is a true genius of our day and a very good communicator. You have to listen, even if you disagree. I find it very hard to disagree with Sean.
At night I’m half awake and at day I’m half asleep. Superposition!
this is literally my life - HELP
Naa you just don't sleep well.
Superposition would be fully awake and fully asleep at the same time, a bit like we all are in this non existent illusion we call reality.
60% of the population lives like that....and is not a joke !
As soon as I see a new lecture from Sean , I immediately click.
In other worlds however, the click is slightly delayed
Yes, and some day we'll figure out what he's talking about.
When there's a new Sean lecture, my mind says YOU'VE GOT MAIL!
Then Meg Ryan comes into my room.
What do y'all think will happen if we have an AI observe waves, would they turn into parties?
Me, too!
What a brilliant mind...so open and accessible...
For a reason I haven't yet pinpointed watching this really made high level quantum computer understanding click and make sense!
Wow.
Once again, Sean finishes a lecture and all I can say is wow. What a great explainer. He makes the subject so simple that even a being made of quantum fields can understand it!
As an engineer, I'm used to thinking of classical mechanics: balls rolling down hills and trains going different speeds. But now, quantum physics says, "Forget classical mechanics. Don't picture balls, trains, particles, bullets, atoms.They went out with Newton (and way back to Aristotle). Think of FIELDS... ripples on a pond. Forget the stone that caused the ripples. Just look at the waves in the water."
So now I think of the world like trillions of ripples. You and I give off ripples in space and time. The Earth gives out lots more ripples. The reason I stick to the Earth is not because a force is pulling me down, but because the Earth gives off many ripples (waves) than I do and they distort space. That distortion is what we call gravity (which we can't see happening!).
Anyway, I'm picturing the universe differently now. I don't see particles... I see waves aka ripples. Extrapolating, where enough waves meet at a given point, they act like a solid particle. But the wave came before the particle. How am I doing, Sean?
Now think of waves as vibrations then resonances....
I like this. I remember watching Krause years ago and being impressed and I got the same feeling now.
Might get the book (from the library)....
Jonathon Jubb having fun isn’t hard, if you’ve got a library card
buy it! you will not be sorry and it will still be a good read the 10th time....
Blessed to have this opportunity 🙏
What an awesome talk? Love his style...
Working through the book. I find it understandable but maybe I’m biting off too-large chunks too infrequently. This lecture helped me refresh and reprocess. And for the love of cats, don’t read the comments on this video.
As far as I'm concerned, Everett was right. Universes are made of particles, reality consists of multiple universes and the wave equation tells you how universes are related to each other over time. When you make a measurement, you get some information about which universe you are in. In other universes, other copies of you will make different measurements and learn something about which universe they are in.
Did I misunderstand anything?
Spot on! The true mystery is "what is consciousness?" The thing that allows us to observe our observations?
@@secularmonk5176 Ahh, the hard problem
Very clear and interesting speech. The ideas he talks about seems very natural and at the same time very mind blowing.
I enjoy listening to Chef John and this guy
Sean is a great explainer. Loved the entire talk!

Well put. Easy to follow (for me) and I am a social scientist…. I am looking forward to 1) if it changes our view on the universe we see. 2) If there will be any way to prove it. I do love the emergent gravity that comes out of it. Susskind is on the same path, I saw in one of his videos.
Sean is always a legend but here he was in motherfucking GOD MODE! damn.. such a legit talk
I agree. Saw one of the best threads
On light speed, gravity etc etc. the best in a long time. I’d love to
Get Sean’s opinion; check it out...
God mode? Is that the one where you are not making any difference because you don't exist? I would argue that Sean is in way more powerful mode in this talk.

John Gomes haha that objection made think of “... too many notes.., just cut a few and it would be perfect” from the Emperor in Amadeus!
I DO.
This is million time better than sci fi movie. Nobody can write a wired intresting and spooky story line like this
I like the question about running out of branches. I would like to speculate that as times passes, and the total amount of possible states increases, detail gets discarded because total information is finite. That's the materialist view of the entire universe. I even think most of the confusion comes from the fact that looking from our personal perspective (we are conscious parts of of this quanta), we also feel that information is finite but this time the total amount of possible states keeps decreasing while detail gets filled in. In other words our mind seems to merge repeatedly towards a more and more detailed picture, contrary to the universe which keeps branching and discarding. Then from a human, collective perspective, you hit a nice middle between the two. There seems to be a stable, renewing flow of possibilities if we don't fill our consciences with useless information.
Thank you so much for getting into what is measurement.
Love what he’s preaching man. Let’s get to the bottom of this, not just calculate. Rock on
*_...but, everything, is measuring everything else,-so observation must be a collective, operation... even when you're not looking for yourself right-then... try catnip in your box so it's either going nuts or it's not, which is very subjective to your point-of-observation of cats..._*
Spot on, thank you everybody, Doug:).
Raises her hand from deep in the Heart of Texas! Love you, Sean.
I like quantum field theory. i can appreciate and understand quantum field theory as a basis for reality. what I can't wrap my head around is how shrodinger/Everett fits into the quantum field theory. I guess they are dependent on other dimensions/many worlds, etc... but I can't understand how many worlds can be a basis for reality. I think we are missing something.
everything is conected to everything
Without the many worlds element, you have perfect order at the beginning of the Big Bang and Hence you have an anti materialistic answer which doesn’t sit well with an atheist. So the only way out is to create without no direct evidence just assumptions an infinite multiverse with infinite amounts of chances at life, hence a materialistic world is still slightly possible.
One thing that always bugged me about the shröedingers cat thing is....
Isnt the CAT itself an observer? Isnt the microscopic bacteria on the glass vial, observers?
Isnt the quantum fluxing virtual particles popping in and out of existance, occasionally colliding with the transistors in the sensor that triggers the hammer, also collapsing the wave function as they interact, however minutely, with the system?
The universe itself doesnt require a human or robot to observe a state, the universe observes itself, continually, constantly. You already touch on the fact that its not wishy-woshy conciousness that collapses the wave function. So then, why dont we consider the CAT in the equation? It itself surely knows what "state" it is in, if its dead or not. Thus, the outside measurement is irrelevant, because the wave function collapses as soon as ANY "event" takes place, as soon as the cat dies, or doesnt die, the wave function collapses. It cannot exist in two states, beacuse the cat itself is observing which of the two events occur.
(As a more simple example, you'll stop hearing it meow, or you'll start smelling its rotting flesh)
Also the box isnt an isolated universe, it's connected with everything outside no matter what you do, but thats the same mistake of theoretical fallacy that the thermodynamics conservation of energy makes, imagining that the universe is an isolated CLOSED system, when all observations point to the contrary (is there ANYTHING more OPEN than the universe? lol).
I'm not saying equal and opposite reactions isnt true, im just saying we cannot say for certain that mass / energy cant be created nor destroyed in the universe, before we know if the universe IS a closed or open system. Especially when everything points to it being OPEN (even if you take the big bang theory as the universe as a "bubble" of spacetime, you still have theories of membranes interacting or wormholes forming between universes, ANY of those are breaking the "closed system" that thermodynamics assumes as fact).
Sorry lol i went on a tangent there..
interesting, but i think consciousness has different levels .
Interesting point here, but it is fundamentally wrong, and this is provable through the double slit experiment.
You're actually confusing observing with measuring and you're mistaken thinking that the wave function somehow collapses every time we happen to observe it.
As proven during the double slit experiment, the wave function only collapses at the act of exact measurement (when photons pass through detectors,) and not during the act of observation.
So no, the cat itself is not capable to collapse the wave function in this specific experiment, furthermore so because Schrödinger's cat
involves the use of a quantum device that has an exact 50/50 chance to either kill the cat or not kill the cat. The cat itself does not know what is going to happen or what is going on inside the device, and the wavefunction only collapses when the device triggers and an outcome is chosen.
A great talk and much more accessible than one would think when approaching such heady topics. Regarding the many-worlds interpretation, I do believe it to be yet another way to hide the fact that there are things we just don't know.
Effectively, we are saying that we don't know what the state of the universe will be at time T+1. But why don't we? If each state is a function of the previous state, then the universe is deterministic. If our calculations do not correctly predict the next state, then it must be because the calculations are incorrect. Or more likely, lacking the vast number of variables that we would need to observe from the previous state.
The issue is that we don't know the entire state of the universe at any moment and so therefore cannot predict the next. We introduce probability to add the fuzz factor that gets us to something can almost approximate the chaos quantum mechanics.
I LOVE Quantum Mechanics. Solving the Quantum Theory is a joint effort. Scientists then have entangled work to do!
This is the version of Sean Carroll convincing us to believe the many world interpretation. I would rather watch the version of him explaining how the Copenhagen interpretation was correct, i.e. in another world.
but you should. Copenhagen Interpretation is wrong
You're in the wrong universe. The rest of us watched stephen hawking giving this talk.
@@bobthedemon1975 In another world line Donald Trump is the world's greatest quantum physicist. Does that disprove the many worlds interpretation?
Huh. Gravity brings things together but may drive expansion. A quantum theory almost seems like it would be recursive / fractal. Like.. if you're far away then its uncertain if you're affecting anything and over time you become less and less relevant as the cumulative irrelevance builds up. But if you are close, you ARE relevant and it cumulatively builds up.
entanglement is the form matter is united
Brilliant brilliant brilliant. So well done. Thank you.
Yes, he brilliantly tells you total bullshit and you are eating all of it. For starters: there are no particles. That's why we call it "quantum mechanics" and not "particle mechanics". ;-)
I had to add an additional thought about Carroll's lucid explanations. As Carroll readily states, his story about QM (a version of Everett's "many worlds" or multiverse) is not shared by the majority of physicists. What is so refreshing is that you can consider the different POVs and draw your own conclusions about the nature of reality. No fake facts here, just insightful discussion. How refreshing.
There are fake facts here. Like Popper being one of the biggest fan of mwi. That’s BS. In his book he explicately denounces mwi.
if we where in a simulation it would make sense to save processing power that each object inside the simulation would sit idle unprocessed until an interaction happened and forced the algorithm to calculate the state of the object.
The simulation hypothesis is so obviously correct. Just doesn't make for a book or a career, except for theologians. Let's face it, 100 years of trying, you aren't going to unlock level 2 unless you worship the simulator, because that's what he wants. So be it. Fine then. It's not as difficult as trying to get my head around the twisted logic I'm seeing here.
that's different. You would never discover that. Thus/And that doesn't predict the specific way that the observed states are generated. Think of video games that don't show quantum behavior to us, only classical behavior. It's thus of no value in this debate, and acquires no credibility from quantum mechanics.
Quantum physics has hit a fracking brick wall.

#WaveParticleDuality #TheoryOfEverything
What if strings aren’t vibrating string loops, but rather particle orbit trace patterns?
The natural first (Occam’s) assumption to explain how or why a particle like a photon (or electron, etc) might behave as an uncertain location particle while also like a polarizable axial or helical wave ''packet'', given that everything in the universe from electrons to solar systems are in orbit with something else pulling them into polarizable axial or helical apparent waves depending on the orientation of their orbits as they travel thru space, and given that we know we’re in a sea of undetectable dark matter but don’t know where it’s disbursed, is that they’re in orbit with an undetectable dark matter particle pulling them into polarizable axial or helical apparent waves as they travel where the speed of their orbit determines the wavelength and the diameter is the amplitude which would explain the double slit, uncertainty, etc. No?
nobody believes they are vibrating string loops, it is just a description that allows you to grasp the concept of excitations in a field....
This video was fascinating! I really like this guy!

Electrono9 Pain. Pain is in the box.
Good talk, he explains it well.
1. Entities in a superposition are in a superposition of well-defined states. (Spin up / down, cat awake / asleep, electron located here / there.)
2. Entities in a superposition don't experience that they're in a superposition. (They experience that they're in a well-defined state. Because they *are*. Just more than one of them.)
3. The states that are superimposed never interact. (The awake cat and the asleep cat are separate worlds.)
4. Entangled entities experience each other as well-defined. (They're in one collective superposition. Measurement / observation is just entanglement.)
5. Decoherence is when an entity is entangled with the environment. (Where everything experiences everything as well-defined.)
The worlds of the Many Worlds concept are the individual states of the superposition.
The apparent collapse of the wave function upon measurement is the entity becoming well-defined to us when we become entangled with it (#4). What really happened was its superposition still exists but now includes us.
mediawolf well written 👍
Carroll uses the Everett interpretation of QP or "many worlds" to explain the Schrodingers Cat "thought experiment." Presumably this also applies to the famous "double slit experiment," where final results differ, depending on whether the waves/particles passing through the slits are "observed" or not. It would seem that the "superposition of the entire system," where an observer is included in one system and no observer in another, determines if particle points appear on the wall behind the slits or if wave interference pattern dispersions are seen.

If Sean is correct about entanglement, I guess everything in the universe is coupled regardless of spacetime. The obvious question then is why the universe exists at all.

Interesting talk. The many worlds theory makes sense and does seem to reconcile some quantum mechanical theorem. I have a friend who once said that maybe that's what happens when we dream. The electrons from the electrical impulses in our brains jump to other branches of existence. That would mean we would not be be the same person between conscious states.
All in all, enjoy life as it is. You'll never know what will happen in the future as you are never going to know which path split of life you'll take. Just embrace yourself as the quantum observer of the specific quantum state where your life is pathing on, and let go regretting deeply on past mistakes because you're just experiencing one of the multiple quantum states of your life.
What's the difference between Many Worlds and one world, where the others aren't actually "there". And since we only experience one...
... It is true: if you lock yourself into your house that you live in and live only there you wouldn't care if there are other houses... not even of acknowledging the possibility of them existing... at least just for the sake of seeking for the "real truth" and understanding that we are far smaller than we thought we are. Then you probably would ask yourself what in the world wanted those men, strange figures, who say any other things like E=mc2 or similar... your rhetorical question sounds very anti-progressive.
I like to think that if there was only one world then I wouldn't be here. Because it seems highly unlikely that I would exist at all.
The wave front is a Higgs function. There is an actual particle which is a knot of energy. Those straight line tracks are a lot thicker than the size of the knot. The size of the knot is the size of the orbital of the electron in a atom. Hence, in the 2 slit experiment, it is the Higgs field that goes through both slits, and is affected by the Higgs field of the material the slots are in. The actual electron goes through a single slot. There is no infinitely branching universe.
Sean Carroll is an absolute OG
Key is information preservation. Storage of physical information of what happend before, so there can be build upon.
Could dark matter actually be the effect of the many worlds on our experienced version?
Exactly what i was wondering. Esspecially since the universe is expanding in a ever increasing speed. Maybe gravity bleeds through the branches of reality.
I've always thought of dark matter as the memory bank of all metaphysical "stuff", assuming one believes in things like consciousness and so on. I.e., where is consciousness? Maybe it is defined somewhere in dark matter.
Arnout van Buul haven’t we tested this? When gravity waves were were detected they were exactly what our measurements said they would be not accounting for extra dimensions. If there were extra dimensions it would have been less. So supposedly this means more then likely that NO there are no extra dimensions.
I just figured out that the cat in the box is an observer and measures itself as awake of asleep.
I choose to believe he knew that and he never risked an innocent kietsie cat's life.
wouldn't the cat have to imagine an observer?
@Lavalambtron is that to say the cat doesnt exist until you see it?

If you want someone to read a difficult book you like, say “I always get something new out of it” instead of “I’ve been working on it for years and still haven’t fully grasped it”. Quantum physicists are being self aggrandizing by stressing the difficulty
but it is difficult, and pretending it isn't does not advance anything....
