Something Deeply Hidden | Sean Carroll | Talks at Google

"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.

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.

[@MrEiht]

@Via hahaha epic!

[@spaceman081447]

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."

[@rc5989]

Sean Carroll is my favorite living physicist, ainec. I can not wait to get my copy of his latest book ‘Something Deeply Hidden’!

[@sekoivu]

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."

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?

[@The22on]

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?

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?

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..

[@lifewithAysha]

interesting, but i think consciousness has different levels .

[@BeelZeDemon]

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.

[@TheIllerX]

Very clear and interesting speech. The ideas he talks about seems very natural and at the same time very mind blowing.

[@mediawolf1]

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.

[@gotnoshoes22]

that's different. You would never discover that. Thus/And that doesn't predict the specific way that the observed states are generated.

[@io3213]

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.

#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?

[@DrPommels]

nobody believes they are vibrating string loops, it is just a description that allows you to grasp the concept of excitations in a field....

What's the difference between Many Worlds and one world, where the others aren't actually "there". And since we only experience one...

[@ivandan1174]

... 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.

[@timo4258]

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.

[@Hephaestus512]

This video was fascinating! I really like this guy!

[@Andrew-tu5fm]

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.

[@edoblaauw4561]

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.

[@-Gorbi-]

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

[@DrPommels]

but it is difficult, and pretending it isn't does not advance anything....

[@coastwalker101]

Good talk, he explains it well.

[@thomchristensen990]

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.

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.

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.

Having studied pure mathematics I have a firm belief that Nature is beautiful. Dr. Carroll's approach of showing how gravity could emerge from many worlds quantum mechanics is where I place my bet.

[@espaciohexadimencionalsern3668]

what if light jumps when reaching 300000km/s times 10 as fast lets say10 to the 22 or more each time would we see it? i think we did and is what happens whene they see the atoms in two places at a time, the thing that it is is that: imagine a marblel in a band that comes and goes, you will see that the marble moves to one side then to another, and it will look to you that the atom is in 2 places at atime but what realy is is that the energy flows so fast that tou wiil see matter when it stops in one side and when it stops in the other. its not to imposible to BELIAVE OF HOW FAST ENERGY IS.

Could dark matter actually be the effect of the many worlds on our experienced version?

[@arnoutvanbuul6425]

Exactly what i was wondering. Esspecially since the universe is expanding in a ever increasing speed. Maybe gravity bleeds through the branches of reality.

[@lansanacamara4148]

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.

[@trex1652]

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.

[@bennettwaisbren]

There's a line of logic in our code that states "if user observes fundamental structures of reality, jumble the results"
