The Nobel prize in physics is typically awarded to scientists who make sense of nature; those whose discoveries render the universe more comprehensible. But the 2022 Nobel has been awarded to three physicists who revealed that the universe is even stranger than we thought thanks to Quantum Entanglement

Going against both Einstein and Feynmann, I guess they were *super determined*
@@unbearablepun8608 apt username
I both hate you, and love you.
Are you my dad?
Bell himself, who proposed the Super Determinism explanation of quantum mechanics, would love this comment.
Including your comment.
😂😂😂😂😂😂😂😂
It blows my mind that in one hour you have 25,000 views about an obscure problem in quantum physics. I am glad to be in the company of my nerd brothers and sisters. There are more of you than I suspected.
Sup, fam?
i honestly love these topics im not even very seasoned in mathematics, but phantom matter and this credit towards quantum entanglements research really has me high in spirits. Its humbling to remember how small/significant we are from time to time. Seeing how far the particle acceleration field, and quantum field has come towards pushing the envelope of the UNKNOWN has me so happy that as a human race our drive towards feeding a curiosity has not escaped or locked down or held back the frontiers of science.
It's now 55,000
@@phily-hu5pr So....many....nerds....
they solved this on ant man and the wasp new movie quantanium!
What a time to be alive. I'm 8 mins into this and clueless but just happy at the strides science has made. Incredible.
In other words, esoteric claptrap is all you need to believe in a specious theory as enormous as quantum mechanics. 🙄
String theory also sounds fascinating but it's meaningless.. if you don't understand it how can you know its not bs?
*Soon, somebody will prove that astrology is true and planets affect us.*
@@YOTUBE8848 well the planets must effect us they can't not effect us tbh

Quantum mechanics feels like those math questions you got right as a kid, but when you showed your work, you were going about it wrong.
YES THIS AFGSVZBZ
Even though you know you were correct
Opposite. The methodology here is rock solid. Hence the experimenters won the Nobel. Yet the results make no sense to the classically conditioned mind.
Yeah then they take all the claim through your work. Might as well stand in front of a mirror and say I'm right and you're wrong. Obstinate bastards.
It looked wrong THEN. Mathematicians used to be averse to imaginary numbers, they gaslit themselves into using solutions until they got the results they wanted, at the cost of going further and further away from the actual results.
I just want to say this is the only channel thats getting better with age, thanks for not underestimating your viewers.
Absolutely! PBS SpaceTime is like 10 seasons show, you can't start watching from season 10 and expect a great understanding; you have to start from the beginning. And as a veteran viewer, I do also think to start over from the beginning for some time to brush up my knowledge; I also want to take notes next time, I just don't have the time and focus yet.
Exactly my thoughts too. I'm so glad they maintain this level of quality without dumbing things down to the point of cliché or inaccuracy, like so many other science educators do.
Indeed, I'd rather know if something doesn't make sense that's it just because I'm an idiot, not because the show I'm watching is.
Meh... not so sure. The "Edge of the Universe" episodes were the peak, let's be honest. And that series on string theory (is right/is wrong) was much better than the past year's episodes as well. But then again, when you're this good, it's easy to blow your wad early.
"The only channel that's getting better with age" A) wrong, it's not better now than it was than the last guy, you likely just mean "more entertaining", which arguably it is, but this being a teaching channel is dead and has been for years now BUT ALSO B) even if I DID agree with you, you are being needlessly myopic given many of the channels that HAVE gotten better.
As a non-physicist, I feel I won something whenever I can follow your videos all the way to the end.
Definitely. I have been bashing my head off Astrophysics and Quantum Physics for over two years, and I'm only just starting to get even a basic understanding of what we *think* we know so far. I love this channel for ideas and theory, and I also love Anton Petrov's channel for latest news about various discoveries and mysteries of Astrophysics.
Here's a take you might like, by the well-known Sean Carroll.
From his perspective, literally anything that can happen, the slight deviation in movement, spin, path, or whatever, of a single quark, all the way to the largest, incomprehensible cosmological events all does happen at once, sort of like the Multiverse interpretations. Yet what we see at macro scale Reality, is only where these things overlap the most, with the rest disappearing into oh no I can't remember and I've gone cross-eyed.
Yes thats Matt's talent for getting this through in the layman's terms

@@woodynotes No I really don't know a whole lot and I'm utterly confused by about 90% of what I've tried to learn so far, sorry
Feynmann would never say it was wrong to try, he was saying it was impracticable for that lab at that time; not the same thing. He was not closed minded and well understood the value research of this type.
If you can prove Einstein wrong in any way, you will win the Nobel Prize in Physics.
So if you can prove those who have proven Einstein wrong , wrong themselves then you must win the Nobel Prize in Physics …. I love quantum physics !!! Max Planck is one of the hero of it !! ….
@@Kassiusday To be honest, they have not proven Einstein wrong. They have probably proven Einstein wrong, which is not the same. Quantum theory is always probabilistic. How probable are they? As probable as it is not probable. Their theory is technically in a superposition.
@@r.davidsenhello Thank you for your comment , because I did have the same reflexion : in quantum we are referring to statistics and probability and we fix the result ( collapsing the reality ) as soon as we are observing ( we involve our consciousness !! So are we living beings , existing beings or are nt we ?? And as you leave your cup of tea ☕️ on the table when you go to the toilet 🚻 that cup of tea can be anywhere in that room you just left … or might be also not present as solid cup of tea anymore but a wave fonction of it // here we go superposition of probabilities … nothing turns to be real in Quantum Physics . but a probability / however having said that .you can deny that distance seems not existing so as the time , at that level ….Einstein still scratching his head …
Objectively, the haircut was wrong... my prize please
@Kassius KLAY there is no consciousness involved, you're just repeating sensational Google bs people read. A particle exist as a superposition of states and has no deleyed will or hidden variables. The point being once information about an object is taken such as speed,spin position , etc ,the variable can no longer change, yet up until that moment the object has not collapsed. This can be caused by objects without conciousness once so ever.
It's like a turtle hiding into its shell after being affected by external stimuli, an observation in scientific terms means "collection of information" as opposed to "eyeing it"
The misunderstanding about it generaly comes from eraser experiment. People don't understand the mechanic and read made up headline which is no different to celebrity gossip site
I think I'll dress as a Quantum Entangled Particle for Halloween this year and tell everyone I'm causing spooky actions at a distance.
I’m stealing this idea and making quantum mechanics jokes all Halloween.
Not a perfect idea
Reported to the joke police.
You missed out on doing this during the lockdowns.
Have a one-time pad in your pocket. It can travel faster than light.
Man, you're good. I have a master's in physics, but haven't been working as a physicist for a long, long time. You single-handedly revived my interest, updated me on more recent understanding, and helped me understand certain concepts that I should have understood at the time but didn't.
If you like to find an easy explanation of this and other mysterious phenomena, I will recommend you my book - "Theory of Everything in Physics and The Universe"

Einstein actually came up with quantum entanglement; he deserved a nobel prize for that.
They gave it to Obama instead. The true winner.
He called it a paradox.
@@debasishraychawdhuri But it turned out to be true.
4:11 I appreciate you using phrases like "dogma" and heretic when referring to how the debate around quantum entanglement developed. It reminds us that even if science holds at its highest ideal that truth is what matters, it's a system acted out by humans, whom can easily lock down thinking that falls outside the accepted narrative
*who
Einstein and Feynman never asserted their beliefs as fact, as their careers moved in different directions in line with what served their place and time. Physicists are not always based.
@@zanegoofgodfrey3540 I never said all physicists were biased, man. But the collective CAN become almost aggressive in knocking down hypotheses that go against what's currently the working theory. Just like how the catholic church silenced anything around heliocentrism.
I remember a domcumentary of just how long it took Einstein and his supporters to convince the scientific body to budge on relativity - which is a good thing generally- but I think many were dismissing it off-hand
...only a genius or a fool would risk their whole future career on the gamble of some revolutionary new point of view.

truth brother
The episodes where you describe experiments and how conclusions were drawn from them are my favorite. Please do more.
no please don't, we already knew about these experiments. A video on a subject with the adequate experiments related to it is better.
I always wonder how those old-timey physicists figured out very specific things without modern equipment. How much of it is direct vs indirect evidence or logical vs physical etc.
How Matt can infuse humor into these extremely technical episodes as he did in the last Q&A answer is truly brilliant.
hes a troll
My education is in business but my love is physics. I admit I do not have the brain to understand the in-depth aspects of all the branches of physics. This channel is awesome in helping me understand on my level. Thank you particularly as I have a really easy time understanding you and staying attentive.
Same here.
I am from commerce background but quantum physics is my new found love .
Have been following PBS- Space time, Sabine Hossenfelder for a while but I can understand only a bit like 10% of what they explain.
Are there any other channels which are good for beginners like me?
Taking my undergraduate physics classes can be just a constant state of confusion with a few moments of satisfaction attained by comprehending a concept that are quickly squashed by a new even more complicated concept to understand. These videos give me a fun, easy to understand dose of physics that is still new and exciting for me.
I'm right there with you, Luke!
It is not your fault that some aspects are difficult to comprehend because current physics is full of conflicting phenomena and explanations. If you want to understand what's is going on I will recommend you to find my book - Theory of Everything in Physics and the Universe" I wish you a pleasant time.
@@valentinmalinov8424
Your book?
Where it is available?
Did you get the impression that TPTB were BSing you?
Thank you for pointing out that Bell's Inequality and the experiments honored by the Nobel Prize only rule out local hidden variables theories. I'm not saying I'm necessarily advocating for pilot waves or any other non-local theory, but it's been annoying seeing videos discussing this topic completely ignore that they may be disproving locality rather than hidden variables.
Until I saw Sabine's video on the topic, I spent a few sleepless nights worrying about fundamental randomness & non-realism, having only seen glowing headlines. I already knew that these experiments had been done, but I didn't realize they were only now getting the Nobel recognition. So when everything I see just says that the Nobel prize was given out for proving reality isn't real, I get very worried. Luckily Matt and Sabine are here to talk us down.
I'm sure it's in this video somewhere, too, but pilot waves are far from the only escape hatch here. Many Worlds never collapses a wavefunction, so all results still exist and the results don't have to square until they're brought together, at or below the speed of light. It's really very elegant when you look at it as just math and forget about everyone telling you there are branching realities. "Superdeterminism" is the more popular option, though, I believe, and it really isn't different from just taking determinism seriously. With either of those interpretations, you get to keep locality by thinking about realism a little differently.
@@davidhand9721 Just like string theory, super-determinism is a theory that may never be proven right or wrong.
But at some point you need interpretation in order to make sense of the results of experiments. To sort out wrong hypothesis only more and more sophisticated experiments are necessary.
I think 0 is the hidden variable.. it's right in plain sight, but hidden because it doesn't objectively exist.. 0 also cannot defy locality be abuse it isn't matter.. in my thinking 0 is also infinity tho.
@@nickrindal2787 0 is a constant, not a variable.
My friend saw this video and he (a fellow Researcher but in the field of Virology) asked me (a physics PhD) why at 5:58 it is alluded that the entangled photon or electron pairs must have an opposite spin. I had to explain the law of conservation of angular momentum to him.
This video was excellently made and simplified. Due to the uncharacteristically high interests in this topic from non-physics people, it is however good to mention even this simple aspects we usually take for granted.
Great stuff, Matt .... as always. The comment-responses alone were worth the journey!
I realise that most universities have limited budgets and so a head of faculty will deny research funds to scientists who are bucking the favored theory of the day but I love how many discoveries have come from people who refuse to give up on their own theories.It's what science is all about.
Funny the Bible has been talking about these things long ago… the triune God of Christianity…. consisting of three in one (used especially with reference to the Trinity).. God the father, the Holy Spirit and our Lord and Savior Jesus Christ are three separate entities and one God at the same exact time. Quantum Entanglement is the same concept of how Christ was able to walk the earth as 100% a man and still be one God.
This is legitimately the first time someone actually described fundamental quantum mechanics in a way i could at least get somewhat of a grasp of the concept.
You´ve definitely earned a subscription! And you´ve earned it the hard way since i´m not all that clever. 😅👍

Thank god for this video. So many videos said hidden variables had been disproven completely by this when they obviously hadn't. They also really lent into the "universe is not locally real" without explaining what that actually meant, or why the research was limited. Subscribed.

Just wanted to say thank you for working this hard for people like us who are not necessarily scientists or someone important but just bunch of nerds(i say this very respectfully) who wants to learn more about the universe and its mysterious ways without getting to technical about the maths behind it..
I have got bachelor in physics and i have been watching this chanel since i was in grade 11.. to be honest you guys are a big reason for me choosing to go for a physics degreee..and i am thankful for it.. i liked every second of my studies just because of the curiosity that you guys put into me..thanks very much..
The coolest part is that we now know with certainty that Clauser's, Aspect's and Zeilinger's entangled pair partners _didn't_ win the Nobel Prize regardless of where they are in the universe!
Congratulations to this years nobel prize winners. brilliant work. thanks for adding to the universe's entropy! to more disorder! cheers!
The coefficients (1/2s) in the wavefunction before the basis states should be square rooted (otherwise it's not normalised)! The wavefunction itself doesn't provide probabilities associated with each state, not until you multiply it by its conjugate transpose ...
I loved how you stepped through the progress made in good timing, and being engaging.
Love watching the vids! Please don't stop 😅

Dr. Quantum Entanglement has been working very hard in their field for years without the recognition they deserve. I personally congratulate Dr. Entanglement for their deserved Nobel win

I love PBS Spacetime! This episode puts together so many of the elements that give me pleasure. Thank you Matt and team for another informative episode enlightening us lay persons on the sometimes weird world of physics, including the right measure of whimsy to make it digestible.
I tried to remain serious but i giggled at "quantum balls"😅
Was wondering if you could explore the relationship of this to the quantum eraser. The double slit experiment fails to be predictable due to a worm hole between the entangled particles whereby time is irrelevant?
For entanglement to happen, as observed, the particles have to be placed near each other. They cannot be entangled if one of the particles exits far apart, like 100,000,000 miles, for example. Therefore, an ACTION has to take place to get them entangled. If all it takes is an ACTION, like motion, then there must exist in nature entangled particles. Has anyone discovered an naturally occurring entangled particle?
I was moved by the tribute to the young man who was a sponsor of the channel. RIP Alex. 🙏
Coming up with a theory that postulates a model of quantitative relationships and interpretations which fits existing observations and explain existing problems is one part of the scientific process.
The other, more underrated part, is coming up with clever ways to produce viable observations that stress the peculiar corner case hypothesis of said model.
I love the lighting in this video. Super easy and inviting on my screen, and makes Matt look like a handsome rugged science Chad
These videos are always super dense and I've been watching them for years. But it wasn't until I became a nuclear engineer, over the past few months, that I came to really value and appreciate the science covered in these videos. They cease to amaze me!
The phrase is “they never cease to amaze me” not “they cease to amaze me.” Unless of course you meant that you are no longer amazed by these videos
@@sgrey9181it’s a consistent pattern among recent generations that the they mangle common idioms. 🤷🏼
Small mistake:
At 3:04 , the wave function showed is not normalizable (sum of probabilities is not 1) .
Because 1/2 squared + 1/2 squared = 1/2. Which is wrong because it should be 1.
So you need to add square roots in your wave function on both 1/2 halfs.
Thank you 💙
You aren't taking account of the hidden variables. Since they're hidden, they don't appear in the equation.
Just to be pedantic, but 1/2 squared + 1/2 squared = 1/2
:)
0.5 squared + 0.5 squared = 0.5

this channel is almost exactly what i want!!! the explanations are still a little too hard to understand for a regular person so i end up having to replay certain parts or just cant continue paying attention through the whole thing. I really want to be able to watch this type of channel i love learning tho. Please simplify the explanations!!!
Quantum entanglement is usually referring to the entanglement of energy in double bonds to the point of electrons and the bond breaks or the election spins off the halogen or transition metal nearby. The superposition and spin flip issue is the functional quality of the NMR or MRI imaging system. They appear to be mixing their metaphors.
I've always wondered if quantum physics issues arise because we're 3d creatures trying to understand multidimensional objects.
What if entangled particles share a higher dimensional coordinate. Like how polynomial equations can have two answers, entangled particles intersect our 3d reality at multiple locations. So information isn't traveling "faster than the speed of light" but instead it's basically just one system connecting the two points in 3d space.
This could also explain the weird shape of atomic orbitals and stuff in chemistry too. Those might be "perfect shapes" in higher dimensions.
That extra dimensional coordinate would be a hidden variable, and given the results of these experiments, that coordinate would need to be independent of everything else happening in spacetime, if it even exists. For more about this, look up "Superdeterminism"
@@falnica I agree, except the way I see it is the particles are the result of the system, not the system it's self. Like the x intercepts in a polynomial. What we see is only a part of the system. Our reality is the x axis in that analogy.
So the particles might not have the extra variable, the system that exists in higher dimensions have the variables. The particles just intersect our 3d reality at those points.
And us being 3d entities are trying to reverse engineer the system from our limited perspective.
I dunno to be honest, that's just sorta how I've always imagined it working in my head, and "dark matter" is just these systems that dont intersect our 3d reality; however, it influences the rest of the systems that do intersect our reality
@@KastorFlux I never forgot about time?
I’m confused about your argument. I’m talking literal spatial dimensions
@@KastorFlux no time is a temporal dimension.
@@KastorFlux I mean instead of arguing a fact, I think you should Google first.
I’m not going to get derailed from my original argument as this is irrelevant. Even if your argument was factual, I still believe there are more than 4 dimensions.
Also, you keep adding “lol” to the message condescendingly, but you should reevaluate your confidence. Invest in some humility, it’ll save you from looking foolish in the future.
I love watching these! Especially the parts where my brain gets entangled, and then untangles a bit as the details are shown. I call it the "Neuro-quantum antistupification effect".
Whether you understand it a little or a lot I just appreciate the opportunity to see more information on the nature of reality. There is so much we don’t know and so many ways to tease it out of the universe. The next couple decades are going to be wild.
Well said
WOW!!!
AWESOME RESEARCH!!!
Biggest criticism of Zeilinger is that he always makes it more mysterious than it needs to be.
That's sort of true of most populist science when it comes to quantum mechanics, they tend to play up the mysterious and magical - rather than using terms like "we don't, as yet, know how this particular thing works".
I dk man. QM is pretty wild.
If you don't make QM sound like dark sorcery... are you a real scientist?
@@JudeMalachi : Alternatively, it's the Locality assumption that's wrong, not the Reality assumption. Note: in the EPR paper, Locality was named Separability.
@@JudeMalachi I'm in the field and likely just biased cause I read a few of his papers where he could easily have been more pedagogic (but likely then those papers would have had lower impact if not intentionally made mysterious).

Gd morning. Thanx for sharing this video with us all. ✌✌
I really love how you go in-depth into the comments at the end of the videos. Really stellar teaching there!
"Put one of your balls in a box and send it to the moon" ouch😅
Clauser's experiment focuses on two separate photons. The entanglement should have been studied on different characteristics of a single photon.
The enigma of being marooned in a simulated environment, reminds me of the story "Lord of The Flies".
You have normalization error, at 3:34 it should be 1/sqrt(2) and not 1/2 as is shown in the video
while I don't fully understand every topic you share with us on thew channel I appreciate that you don't shy away from talking about the more difficult to understand subjects
I’ve been researching quite a bit about Alain aspect and quantum entanglement since I have an assignment to do and my brain is now completely fried every time I think I got it they would introduce a new idea I’m honestly thinking of failing it by now😅
Well done Matt on your fluent descriptions. I have one question regarding Quantum entanglement and the principle of instantaneous action at a distance. Assuming the two entangled particles measured by Alice and Bob, are each taken in their spaceships going in opposite directions at speeds that create some measurable time dilation; when the instantaneous action happens, do Bob and Alice see the effect happen at the same time, or is the ‘instant’ measured as being at the relative times of each? If the latter is true, on one objective perspective, the action takes place at a future time relative to the other and creates an interesting dilemma. If the former is true (ie at a time agreed by the observer to be the same (not sure how), then Alice and Bob measure the ‘instantaneous action’ as taking place at different times.
I think it's important to keep in mind that just because we have a strong idea we know something, it's still important to test it in different ways.
Love that you guys do tributes for people in the community!
RIP and respect to Aleksander Henry Sajewski.
I'm so glad I found this channel you are fantastic to listen too
My personal gut feeling is that it's not so much "hidden variables" as a system we don't understand. That is, I think both relativity and QM are very good approximations, but there's a system that ties it all together and explains the "spookiness"
Consciousness being the substrate of reality projecting spacetime
@@ShallowedOutGolf That's pretty much what Planck said
@@ShallowedOutGolfso every conscious entity agrees on this perception?? 😂
@@coolblue5929 Basically what’s going on is there’s a substrate of reality of logic/syntax.
The self referential nature of this logic/syntax at an infinite scale is cognition/consciousness and teleological. It referencing itself at an infinite scale produced cognition and self awareness.
Because it’s infinite it has the nature to explore itself infinitely.
Space time and the human experience is an interface or useful fiction for this consciousness to simplify.
Ex. When you drink a glass of water it looks to you like you picked up a cup and drank it. In fundamental reality it was trillions x trillions of computations that you in the human experience couldn’t instantly perform.
@@ShallowedOutGolfgreat, thanks for word salad/explaining.
As soon as I saw the video title, my future has became pre-defined. I liked when one of the physicist said that you are a Carl Sagan of our times.
What a time to be “alive”
What a time to be dead and alive at the same time
To be or not to be, that is the question of our free will.
I came, I saw, I held on to my papers!
I think, therefore I am unsure.
"Say the Lagrangian in front of a mirror 3 times..." I love these kinds of jokes... laughed so abruptly that my coffee went up my nose. LOL Thank you!
Excellent analysis to such a highly controversial subject, kudos!👍
Fantastic video as always, Space Time team! Superb explanations here, and the boxing at 3:50 was very clever!
I'd straight up tell Rich he's less than a scientist if he opposed my testing him right/wrong. That's exactly what being a scientist is. Always testing things right and wrong hoping for the most accurate outcome.
It even seems a little out of character, compared to what he wrote in his books.
He'd get pretty salty when people challenged his view of things. He was usually right, though, which is both annoying and hilarious.
Dogma is not becoming of any scientist.
@@hoebare Feynman was famously anti-philosophy and very much in the "Shut Up and Calculate !" school when it came to quantum foundations - basically, he thought it was a waste of time and that physicists should concern themselves with _using_ quantum physics rather than worrying about what it all means.
Very glad this video didn't let him off the hook on that score (because I fundamentally disagree with his position).
So the programmer of the universe uses global variables? Very hard to debug that kind of code.
Not global variables. They use Lazy Evaluation.
@@mikkel715 or maybe memoization. Or recursion unrolling… I wonder how big a stack space is reserved for reality.
@@NoahSpurrier Stack space is limited or say optimized to share wave function reality until observation.
Hope not they use loop unrolling &**+3
@@mikkel715 I’m wondering if there is a way to craft a buffer overflow code privileged code insertion hack without a segfault causing the universe to dump core.
@@NoahSpurrier Some sneaky tweak in the delayed choice quantum eraser with circular reference.
I'm no scientist by any means, I'm just an IT guy with a passion for physics and I just want to say thank you to you and everyone in the CZcams science community for bringing the joy of science to a layman like me, once again thank you ❤️
I was personally saddened at 5:45 when the analog synth sounding arpeggiator finally stopped looping and the sad piano was switched on. I’d be happy to make you some more arpeggios if you’ve run out PBS.
I really appreciate that you're bringing the remarkable work of these scientists to the public! But I do feel obliged to point out that Alain's last name is not pronounced like the English word "Aspect" but more like "Aspay", long e on the end and silent ct. :)
Great episode. I'd love more episodes that start with a theoretical concept like "delay the measurement" and show how that is done in an experiment.
This is awesome work. Once again PBS spacetime knocks it out of the park with explaining things.
I am just so amazed by the knowledge of the physicist. To understand these principles, write the formulas, explain something that you don't see, etc. Even if you simplify the explanation, the ordinary viewer like me will never understand this.
Sean Carroll's latest book is exactly about the fact that the average person _can_ understand this. Not in excruciating detail but it is no impossible feat for "normal people" to understand how the equations work and what the symbols mean and how to use them to understand things we don't see.
Perhaps you'd be interested in his "the biggest ideas in the universe".
A tiny remark, the wavefunction constants are 1 over square root of 2, since the probability is the square of the constants, such you get 1/2 as the probability for each state.
I'll chime in with support for episodes like the previous one! I'm nowhere near good enough at math to comprehend it all but seeing these kinds of things explained does at least give some insight into things in broad terms. While I don't really understand them I'm glad someone does.😁
Entanglement surely can be used to send Mesages infinitely-fast, right?
@@loturzelrestaurant that's one application that we would want to use this research for.
Quantum theory -->> Imagine a red ball that's spinning... Except it's not a ball, and it's not spinning and it's green.
Zeilinger also performed the Bell test with quasars, described in the PBS Nova documentary Einstein’s Quantum Riddle.
No, he didn't. :-)
@@schmetterling4477 he did and he won the physics Nobel for Q Teleportation and applications
@@car103d Zeilinger did not create pairs of entangled quasars. ;-)
@@schmetterling4477 ‘with’ (the help of) quasars, of course he didn’t entangle quasars, fussy! ;)
@@car103d He didn't do anything "with the help of quasars, either". Please read the article. Even the abstract contains trivial errors that a high school student should be able to find. :-)
Rating you guys 10 out of 10 and as per my review, Awesome! Always have been and always will be and I HIGHLY recommend. haha. You guys always make this stuff illuminated and tangible.
I remember reading about the Bell inequality and the epr experiment when I was a kid and I'm really glad people went through and did the experiment. One thing that has puzzled me though is why took that experiment to convince people of non-localities/ indeterminism. The thing that really convinced me and frankly it was shocking and very disturbing was the first experiments with single Photon and single electron two slit diffraction. To this day I'm unclear why a careful examination of that seminal experiment isn't as clear an illustration of non-locality/ in determinism. If anyone wants to explain how you can get single Photon and single electron to Slit diffraction patterns in a local/deterministic universe, I would be interested.
I don't understand how measuring polarization tell us something about locality and falsificate hidden variables theory
@@Wiewiurek that's a good question and the answer is covered in other videos. I'm not a big fan of veritasium but he did a good video on this. The long and short of it is that if you assume hidden variables you get a different result by about 12%, then you do if you assume indeterminacy until measurement. If you remember your basic trigonometry you can go through the math and you'll see there's a difference.
A very well presented video with clear explanations and accurate information.
I am a 'superluminalist' so I found it a relief to know that there are researchers out there who may suspect this possibility.
It is an extremely important point that the entanglement before the collapse of the wavefunction is actually a more simple and elementary state than if they carried the information about their final states with them the whole time. I think there is a misunderstanding that this is a more complicated setup than a "classical" setup with more information.
Can’t believe Feynman said no. I thought he was more open minded than that
He’s just a human lol, he can do billions of mistakes
The same Feynman had ignored quarks and QCD at his time in favor of the “partons” model whom he promoted! So he also missed that!
Feynman was tired of young physicists wasting their time trying to understand quantum mechanics. According to me we need to realise that there is more than one way to travel faster than light. If we don’t realise that, then indeed we will be wasting our time.
I believe in a "hyperdeterministic" block universe where the entire past and future are fully realized and always exist simultaneously. It is our consciousness that is traveling through the time dimension in this static, fully realized, fully existent "block" universe.
Agreed!
Extraordinary video
I believe quantum entanglement explains the soulmates concept. As we're all particles
Oh wow! I got it!! Such an excellent explanation of quantum entanglement. Thanks 😊❤
Question: Why is the randomness in the experiment so important?
Because is one of the assumptions of Bell's Theorem. If it doesn't really exist statistic independence between the detector and the particles, because of some "hiden variable", the theorem would be wrong and Quantum phenomena will be local after all
really nice video as usual :), but we don't need animated-pictogram of Bohr and Einstein doing box imo
When I first heard of Quantum Entanglement I was blown away, the more I learn about Quantum Entanglement the more I'm convinced that it's just two marbles of unknown color, in two boxes.
I'd like to hear Feynman's explanation on why he thought that quantum mechanics was always right.
That would be a very informative session.
Superdeterminism is a a bit silly. Not only would everything be planned since the start of the universe, but it would be planned in such a way that it would appear random to us
@@falnica Perfect plot for a Christopher Nolan movie.
@@falnica until we bring the reality of God and Divine Will into the science all the theories are silly.
Because quantum mechanics has always been right. Every single time.
I would love all these videos organized into a playlist ordered by increasing complicity so new ppl can get started
There are several playlists on quantum field theory, the standard model, the lagrangian etc on the PBS channel.
It would be good to put one in a high gravity field and low gravity field then measure I suppose that would take the idea of the two being in resonance in some way due to the time dilatation, ones clock would be slower
I haven't watched the video yet, but what if quantum entanglement is just our best way to explain 4d space.
This would make it so nothing can travel faster than the speed of light
