Time for my monthly dose of “listen to a discussion on quantum mechanical concepts, understand 3/4 of it, forget half of it, try to explain some portion of it to someone, realize I’m an idiot, then listen to more later”
Vicious cycle
My thoughts exactly brother !!!. . . .To be honest, I truly miss the time in my life when all I was concerned about was building ramps to jump our bikes over.
I thought I was the only one
i'm in this picture and i don't like it
Three steps forward two steps back 😂
If you understand 3/4 you're definitely not an idiot
I don't always watch 90 minute videos on science, but when I do, it's a midnight on a school night.
Kalsarikänni mornings for me ;)
A very finnish problem...
I'm an ecologist and not a fan of physics, I have 2 midterms next week and a bunch of assignments, yet I'm watching this video till 3 a.m.
I don't always watch an hour long video about science on my own terms, but when I do, it feels like 5 minutes.
Lol i see what you did there
Well said.
I am 54 and am so enthralled with quantum physics I can’t get enough. I wish I had felt this way in my 20 s. I’m so impressed with the intelligence of these people
I’m 40 and finally falling in love with it too. My daughter is 15 and is not ready to expand past her reality.. “this stuff is weird.” Everything is weird. I tell her, “it IS weird, that’s what’s so compelling!!!” 😂
Same Michelle, exactly…I just turned 54 a few days ago…and I also can’t get enough of this subject.

I’m a 50 year old bricklayer and I’m having a beer 🍺 and haven’t watched anything so good in my life
Brilliant I’m loving it
You shouldn’t be consuming alcohol especially while sitting around watching videos. I bet you were eating junk food also @ the time you posted this. You should be engaging in activities which are more productive, like exercising or drinking something healthier & less irresponsible.
@@macysondheim you're being sarcastic right? Bricklaying is active work, youd probably want to relax with a beer too. My back aches just thinking of doing that at 50
I really dig Brian Greene’s style. He is very good at reeling in the discussion and keeping things focused, then translating complex ideas into intuitive analogies. Some people say he interrupts too much but I disagree, without him the discussion would spiral into confusion for the average viewer. I feel like he gives the guests plenty of room to speak before offering his translations. He would be an incredible teacher.
I think he's annoying, interrupts and talks too much- Even I could do a better job
Exactly what I was thinking. He is one of those people who is really good at directing a conversation, always thinking 5 steps ahead to ensure it's smooth.
Brian Greene provides the inestimable service of making this subject approachable to people who have or would give up trying to grasp it. (me for example) I can’t think of anyone else who does this so well.
Steve, I hope Dave M got to read your comment.
@@scottmorley4981 you hope I read steve's comment? what are you on about?
Brian Greene does it again. He pretends to be the one in the panel of experts who does get it in his humble way so we can all feel better about being part of the subject and then he transposes everything the panel members say into something we can all understand. He can distill all of it for us. He has the unique ability to be the frame that holds the window we are trying to look through. I am no scientist nor am I an expert but Mr. Greene allows me in particular to enjoy being curious about all of this. Thanks again Brian Greene, I have enjoyed all of your publications - written and verbal. TW
I started reading your comment! And I thought you were going to comment! Against him! As I went on reading it was a good comment so? I don’t know why I am commenting!!😁😁😁😁!!!!
I enjoy his lectures so much
And yet I wished he had allowed the others to speak at greater length. I thought his remarks got in the way quite a bit towards the end.
@@yotantontoymeatarantastant6204 I was hoping anyone reading my comment would get through the first part.
@@thezieg He is, after all, the guy responsible for getting the presentation done in the allowed time window.
Even though I struggle to understand easily 70% of the stuff said in this video. I love watching it. It feels so cathartic to see what the best minds in humanity have achieved. We as a species have gone from living in caves to studying the very atoms that make those caves.
Not very far at all in the big picture. If we had more folks who understood maybe 90% of the material instead of 70% perhaps we might be a little further along..
I am constantly amazed at and thankful for the quality of the discussions presented by the World Science Festival! Thanks Brian and everyone at WSF.
I don’t always watch 90 minute videos on science, but when I do, it’s a lecture by Brian Greene.
B. Greene Squad
Mark Van Raamsdonk is a brilliant physicist. His idea of unifying classical physics and quantum physics via Susskind's and 't Hooft's holography, Einsteinian classical gravity and Einsteinian quantum entanglement to explain the structure of spacetime is the biggest leap forward in this area since the establishment of QED in the 1950s. No wonder Greene expressed his feeling of awe and applauded this work. Van Raamsdonk is a Nobel caliber physicist.
This was the most exciting part of the discussion
Nostra Damus I agree, I enjoyed his interpretation very much, "...an entangled universe. "
Exactly Brian forget to mention that Louis de Broglie predicted all of this in 1923. He PREDICTED quantum diffraction waves as quantum nonlocality and he explained WHY it was happening. Not Max Born. So Now they come back to add in relativity. But de Broglie already had relativity in the model. haha. Hilarious. Astrophysicist Paul S. Wesson acknowledged that de Broglie had figured it out - and so Wesson realized the correct model. He didn't get the credit though - oh well. Also B.G. Sidharth should have got the Nobel prize - and he figured all this out. Even Fred Alan Wolf in his SpaceTime and Beyond book - predicted the same model.
I agree, that is amazing! And I've been so into Susskind, and that Raphael something guy. Then this guy is next level. That was a mind blow. Ever heard of a book called The Universe of the Mind? It traces the history of the mathematics and physics in a very 'purely the ideas' way. My point being, it definitely needs to be updated with this concept.
It’s a beautiful theory, like a light at the end of this quantum tunnel
In this time of fake news and mental crazyness on television and the news, it is so healing for me to have found this channel! Thank you for bringing this very highly appreciated knowledge!

only one person insists on using the phrase fake news. you can guess who that is.
41:20-45:50 (Gerard 't Hooft) and 1:15:15-1:15:20 (Mark Van Raamsdonk) : Cannot agree more ..., really appreciate their humbleness compared to most others .... Despite all the hype and at times the fake exaggeration going around / being propagated around by various media too, we got to accept the fact that we are still very much at the infancy, or at most at the level of adolescence, in terms of comprehensively understanding these highly complex systems/phenomena. Modern Science and Quantum Mechanics as part of it may be the best option we've got at this stage, true, still it remains very much immature to cover these aspects in sufficient detail which are beyond our physical/empirical reach too more often than not. Be it Classical Science/Physics or Quantum Theory/Mechanics, all these are just models we have developed with our pretty limited human perception to understand these natural systems/phenomena which may have existed for trillions of trillions of years (or even longer ...). To put things into perspective, we may not have lived at least even 50, 000 years as of now as a (developed) human civilization, our so-called Modern Science may not have any of its roots beyond 5000-10000 years, the majority of our Classical Science/Physics have been developed over the limited time span of last 500 years, our study of Quantum Mechanics has a history of less than 100 years; nothing but an infinitesimal(s) comparatively !.... It may be true that these are the best options we have got at the moment, accepted, but that doesn't mean that these are accurate enough and we are in a position to fully explain all these complex systems/phenomena by using them. Yes, we may keep improving on our understanding/knowledge and get closer to the reality/truth by refining these quite primitive/immature models we've got at the moment, still we might never be able to get to the 100% objective reality/truth ever to interpret all these naturally-occurred highly complex systems/phenomena perfectly .... The (objective) reality/truth is certainly more complex than most of us can even imagine let alone understand, sometimes it may be stranger/weirder than even the strangest/weirdest thing which we may be able to imagine/grasp/understand with the limited system of perception we've been given by nature .... Yes, we humans stand head and shoulders above all other species here (on earth) in terms of intelligence (as per our understanding and definition of it ...) and all our achievements too, still we're only one part of nature and not vice versa, so the human evolution has not given us everything despite how remarkable it seems comparatively .... So we got to be pretty careful/skeptical in interpreting the observations based on our limited, at times oversimplified too, perception/argumentation/knowledge .... Yes, we may improve over time quite certainly and get closer to perceiving/understanding the (objective) reality/truth, yet we still got to keep in mind the fact that we may get only closer but not quite reach there ever .....
This is absolutely brilliant! I've never seen the double slit experiment "live". I also love that the Nobel Prize guest is the only one who brought notes 😄
Holy shit....randonly looking for quantum mechanics videos, found this one, and MY TEACHER IS IN THE VIDEO (Birgitta Whaley)!!! I'm stoked!
Nice
I got a little uncomfortable thinking Brian didn’t call on Birgitta enough, did you think the same?
Lucky you!!
These are some of the only types of videos where i really enjoy sitting and listening while reading all the long comments about others perceptions, the internet really is a gift. Ive just read the opinions of about 20 people that are all complete strangers from different walks of life and at the end i have different perspectives then when i started, even if it wasn't the same as their idea because now i can compare so many perspectives which reveals new ones always! It fascinates me to imagine what knowledge we will have uncovered in hundreds of years if we are here now, for a long time nobody thought of mobile phones but the perspective of wanting to communicate with another creature that you cannt see, smell or feel, resulted in people eventually experimenting on how to do that.
do you ever wonder
@@espaciohexadimencionalsern3668 IF! you were referring to the song then...lmao!😄
I love your perspective ❤️😍😻 even your purrspective!
Too!
like letters? In other languages perhaps? But yeah what a tool the internet is for sharing opinions, one in twenty notwithstanding.
I love listening to this whenever I need to finish something for school, hoping my subconscious mind is studying it for me so I’ll have exciting dreams at night.
What an amazing session! Brian Greene is science’s gift to the general public!
Brian Greene is my favorite. Neil Degrasi is to egotistical he gets irritating after awhile. Neil's wife must be a Saint.
@@mr.eastcoastgrow6132 … 😂 someone who put my underlying nagging thoughts into words.
Kind of, but why does he cut Birgitta Whaley off, put words in her mouth, brush her comments aside, "change gears" and shift the flow of the conversation to other guests in the middle of her comments? Why would he ask a question and then not hear her out, and then shift to, for example, Mark Van Raamsdonk, who has apparently lower verbal acumen with his circumlocutive style?
👏

QUESTION:
When it comes to quantum entanglement, do the two particles measured have to be from the same source or are they measuring two random particles? If they come from the same source do they have to leave the same source at precisely the same time? How do the particles end up in different locations? How is this practicable experiment carried out in the the real world?
NO it was not Max Born! Louis de Broglie PREDICTED the waves in 1923 - he was the one who set that electrons would exhibit diffraction waves because of his Law of Phase Harmony model of quantum relativity. Schroedinger dropped the relativity and suddenly people are seriously confused and lie about the origins of quantum physics - saying it was Max Born who explained what the waves are. Holy smokes! The lies continue!!
Gerard 't Hooft is correct since the new photon experiments are corroborating the de Broglie-Bohm model. We can get "more information" -
The ancients knew this was true due to noncommutative phase of music, as Alain Connes discovered. So 1 is not a number because 2/3 and 3/2 are noncommutative as infinite two-dimensional time-frequency information that constructs the illusion of 3D space as a "zero point." So Gerard t'Hooft is correct - calling it a moebius strip. It was known as the Tai Chi or the Tetraktys or the three gunas of India.
Brian Greene is da man -- the adult equivalent of Bill Nye the Science Guy. I am terminally math-impaired, yet deeply interested in both relativity's time/space counterintuitions, and quantum mechanics' weirdnesses; Greene seems to intuit workarounds for mathlexics like me, so that while I can't "math" it, I can indeed "picture" it.
And his moderation of this assemblage of heavyweights was, in addition to being pitch perfect, also a demonstration of his grasp of the cutting-edge boundaries of physics in general. "They also serve who stand and wait -- and moderate."
Nice dig at Nye, he really isn't an adult version of anything - even himself ;]
@@djosearth3618 I _agree._ Nye and Greene don't belong in the same sentence.
Scary and exhilarating at the same time. And realize that these insights are still the tip of the iceberg. The universe is so awesome.
The general wisdom, and science wisdom at 41:29 is amazing. This is a top notch interview. Thank you.
The host is doing what he was meant to do in life. Host the S*** out of a science show. Very natural. The people working for show/host are serious nerds. They took it to the next level.
Too much host not enough experts.
@@off2theright the experts would talk for days if you don't stop them, and this show is for a general audience, the hosts does a good job keeping it informative and entertaining for the audience, while leading the experts to express their thoughts and some of their frontier research.
This is probably all very simple for those with an education but for the rest of us the host did a great job of making it easy to follow.
I was a bit frustrated at times with how the moderator was interrupting and reining his guests in, but I realized it was necessary so that a simple-minded layman like me could hope to follow along.
No idea why I'm watching this because I know nothing about science but the way they were explaining stuff made me feel like I understand some of what they're saying. I feel like I've learnt a lot but nothing at the same time
This is the most important video I have seen on internet.
This is a marker
The guy with the mustache basically said quantum mechanics reads faith nd has no mistakes. Deeply meaning desires run people
You obviously can't have seen the one with the dancing parrot
@@Bryan-vx7qs How did you came with that conclusion? I couldn't get this same information at all.
AFAIK, our "destiny" is always changing based on our actions and way of thinking just like everything else.
Just randomly put this on for my intelligent discourse fix, and I suddenly realised that I went to school with David Wallace in Bedford. He was a real geek, on the spectrum, and the brightest kid in the year - but we used to have good chats in the library sometimes. He doesn't appear to have changed much, apart from that ghastly ponytail 🤣🤣. God bless you Dave, glad you found your calling and delighted with your success. Physics was never any doubt, Mr Dixon thought you were the return of the Messiah 🤣
Big ups to the whole crew for putting together really complicated physics in a way we can all enjoy in one amazing production. Respect.
No---they've managed to dumb it down to the level of every other broad, basic Intro on Quantum Mechanics on the internet. Such as shame. They had the resources to hit the intermediate sweet spot but chose banality. What a pity.
Thanks to all who contributed to making this amazing science segment!
No doubt this is the best programme.Its access should be broadened.A really great initiative for better understanding of mankind.
The only thing I can say about this video is " The best ever scientific video in my life, and the best ever scientific discussion, an excellent example of driving a person with different idea in coherent way.
Finally the best ever moderator I have watched and listened to it.
I've been waiting for a new panel discussions of this sort from this channel for a year! Thank you for bringing these extraordinary people together and giving us a glimpse into the beauty of this science. Special thanks to Brian Greene and his amazing ability of engaging the average audience like me in such remarkable but utterly complex scientific concepts and let us understand and enjoy it. So refreshing!
"...understand..."? You are a far better man than I. But it sure is stimulating.
@@RobertMcConnell--CT ...as stated by someone else here - I think I understand about half of it until I wake up the next day. It doesn't matter though because Greene makes me feel like I might understand it some day.
It’s so fascinating how by understanding the micro, we can try to better understand the macro. Nature’s design is something I’m not sure we’ll ever understand.
Beautifully executed talk. The sequence of videos and the questions were to the point....Best video on Quantum so far...
Excellent! I'm slowly working through all of these lectures and none have disappointed.
Caught me off guard when they spoke of Hawking in present tense, then I realized this was a month before he died. RIP.
Why are invisible ninjas cutting quantum onions?😢😭
What? Brian Greene passed away?
😞
@@johnimusic12 Stephen Hawking did
Hawking is always in the present tense.
Wow. The things that Gerard 't Hooft says after chapter two is the best. Everything makes sence for me now... The formulas, the physics, the mathematics... Genius
Always a fan of Dr. Green's programs. Thank you sir!
WOW that was the best hour and a half I've spent at the screen for a while thanks and keep on posting !!!!
Literally any topic:
Brian Greene: let's do the double slit experiment!
I spewed my coffee out when I read your comment! You're hilarious!
yeah
Thanks for both the animation /popularization , making quantum theory more digestible!
Some of the explanations are so well put together that I rewind and play them 5,6,7 times to memorize and in turn explain stuff to others.
Reality always entangles me.... "Man must attach himself to an infinite reality, so that his glory, his joy, and his progress may be infinite. Only the spirit is real; everything else is as shadow. All bodies are disintegrated in the end; only reality subsists. All physical perfections com to an end; but the divine virtues are infinite." ~ Baha'i Faith Writings
I agree with the quote on " man must attach himself to an infinite reality, so that his glory, his joy, and his progress may be infinite."
Amen
I love this! It took me years to come to where I am today(it does for every living thing though I suppose😂).
As much as I enjoy the passive knowledge coming into my mind, I would like to express a sentiment to whomever may read this: Let that curious fire to understand burn! Extend your mind into imagination and active projections, be it maths, visualization, art, literature, or any form of information we may come to create in the near future! The world needs someone like you to dance with the awe that is your “mind.”

Just came across this- thank you! what a great panel discussion and quantum levitation show and tell. Awesome!
Absolutely amazing talk. Heat being described as increased probability of different states really shattered some mental blocks of mine. Thank you.
When it comes to quantum entanglement, the experiments I ask the question how much time passes for light, we see the light zipping around the experiment, but from the point of view of the light is leaves and arrives at the same time. The way it’s packaged at the beginning of its journey is how it will be unpacked at the end, and the entanglement is formed at its origin.
The more I learn the more I realize how little I know!

@Roger Loquitur The problems with quantum mechanics And string theory and general relativity
As we all know quantum mechanics is the most accurate out of all quantum mechanics deals with the minute microscopic The building box of everything in the entire universe had a quantum level new discoveries come from quantum mechanics the problem is once you scale up into planets universe is galaxies the area of general relativity Quantum mechanics does not work for everyone tends to forget is like a nuclear bomb it starts off one at a matter of time until you get a chain reaction which has immense power quantum mechanics can be scaled up because in the early universe there was nothing but noble gases hydrogen which then click together collisions and static electricity like lightning to create planets over millions of years through extreme heat and pressure in a constant bombardment of raw materials under multi Red hot material causing more chemical reactions more acids like in a car battery static charges chemical reactions causing runaway effects which we cannot replicate quantum mechanics is the machine that creates item General relativity is the consequence cause and affect like in a guitar the person playing the guitar is quantum mechanics striking the code is string theory how it vibrates and the sound it causes which a third party he is his general relativity
Let’s break it down we know that Adams exist we know that electrons exist we know that particles exist quotes and so on let’s say you were a Quartz which lives inside of an atom you know everything there is to know about courts you know nothing about the item let me know do you know anything about the electron Lebanon do you know about other atoms that make other molecules you are a part of the hydrogen group you know nothing about any other bass material let me know when you would know about the whole body of what you are made of let’s say you were part of the kettle you don’t know anything about a kettle and used to boil water to make a coffee let me know in the human that is making the coffee letter known about the planet you live on that known about that you are suspended in space inside of the vacuum part of of a galaxy and that there is the sun moons other planets and other galaxies in a far far away land those are the dimensions
In conclusion I think that there is the subatomic dimension governed by atoms molecules electrons quartz particles and so on
The next dimension is solid dimension meaning a solid object be it a T kettle to heat water and make coffee beans rocks dirt water oxygen anything solid but not living
The next dimension is for the conscious living item being that they are almost to realms of this I would say the living tree and the living human being self-aware
The next dimension is the missing dimension
The next dimension would be time its self
Where they say length width and depth are all the same thing they are not dimensions the length of a stick is still a stick you have not changed your profile your fuel have you neither have you changed your field of perception the same can be said with width depth is the same thing you have not altered your perception you’re still on the same plane meaning you could run 100 km in one way you’re still on earth you might be in a different location but you still on the same planet whips exactly the same thing that exactly the same thing you have not changed your field of you you’re still on the same planet
All I gotta say is this the double slit experiment works exactly the same way radar was discovered and modified and electron is thrown through a chamber goes past a cavity creating microwaves which then get deflected out in a wave pattern creating radar as we know it it is called a magnetron radar that we still news to this day‘s most scientists would not know this because it is a very secretive and you gotta be in it to know what I say the double slit experiment is creating the same effects as a magnetron radar very easy to test but there’s a lot of resistance yeah only difference between the double slit experiment in a magnetron is that the electron continues on its path opposite the cavity which is creating the magnetic wave which we news as radar the electron gets recycled back through and is a feedback loop double seed experiment doesn’t the magnetic disturbance is going in the same direction as the electron your only difference between the two so if there was a magnetic disturbance Creating a radar affect in the same direction of the electron itself it would be carried on the wave and pushed around which opens up the world to a lot more possibilities if we can push and electron we can do a lot of different things hence why there is a lot of resistance I can say this because I am in the field of discussion
Think about it if any electron in the double slit experiment demonstrates that we can push electrons pause for a second think about that
If you want to get the insight that I know just look up radar and how it was made and how it works and you will now know simple as that
Why it has not been discussed all avenues pursued because there is a lot of division and people have devoted their whole entire lives to a certain cause picture you have devoted your whole entire life proving a fact which then one day was ripped out from underneath you would you not defend it or would you except your face as well as people Benefiting from your delusion buying them self some time
One of the best lectures I have watched so far. Things were easy to understand up to connecting the quantum theory to the black hole. At that point I thought that maybe we could put entangled photons outside and inside the black hole to tell us what is happening inside the black hole. But me then got lost in the idea of wormhole and how entanglement became a thread to connect everything. Will rewatch and thank you very much for the lecture
think of the big bang. something can not come from nothing. so when you see the universe as we humans tend to showcase it like a tube. then the big bang is in one end. but behind it. is the universe in reverse. without the multiverse theory involved. a 2 side universe. like black & white holes. although we havent really seen a white hole yet. but in theory they do exist. its truly an advantage if youre into music to understand. because as a dJ i always have 2 thoughts one for each deck. think of a blackhole like this too. like a battery. you got a plus and a minus. but the battery in the middle is the wormhole that connects the 2. or reject it. always 2 options. or 2 solutions. did you never get this told in life? you can choose to do everything in 2 ways. well i hope i made it more understandable . its basically why humans live wrong . because we tend to make all the easy and wrong choices. but life is not meant to be easy. this is why we wont survive in space without a suit. in such a hostile environment, you cant expect it to be easy to understand either. look beyond humans. that could help too. think like an alien even it sounds bizarre. but it does make it more easy to understand these things. just my bid on making it more easy for more people to grasp. didnt mean to offend or anything. but humans are infact pretty dumb. we are below being kids in space. we are like a sand grain trying to understand everything in the entire universe. search multiverse zoom and watch the video that begins with a firefly. then you know what i mean i think. good hunting :)
I would imagine that way a black hole creates an infinite curve in space time, it would be like trying to shoot a particle out of an infinite Fibonacci spiral in both time and space...so the particles become separated by an INFINITE amount of space and time
Wow, this is great! Love your books Dr. Green!
When there's finally a philosopher on an episode but it's a philosopher of physics

For those uninitiated, please look into the Double Slit Experiment referenced at the beginning. TH-cam some videos. They gloss over it so quickly that it's hard to appreciate what they're saying without previously learning about it. It's also the basis for about everything they're talking about. It's mind blowing!

Could this discussion be any more clear? Kudos to all, very well done.
This was amazing information...keep us posted as you learn more...Thank you to all...!
So insightful. One of the best episodes I have seen yet. Very nice group of individuals.
utterly remarkable! thank you. The bonus of youtube is I could rewind to comprehend some of the tricky entanglement thoughts
Whoa, I thought this was 40 minutes, then I realized it was much longer after I finish, such a good discussion
I've had to rewind and re-watch most of this video ... I'm in love .
This was my gateway drug into falling in love with quantum physics 😍
Only now have I found that I actually did the double splits experiment at high school while studying physic
van Raamsdonk's recent research (quantum entanglement as the basis of space time) is by far some of the most interesting stuff in a while in physics.
Why the proton entanglement can not be explained by the electromagnetic field? Like the positive and negative that always go along with each other and cannot technically exist independently to create energy? Sorry if my question is irrelevant.
Yang mill missing Mass Could be "DARK ENERGY " Existing in a Space field as a vacuum like PARTICLE FIELD with Kahler like Metric Distributed in HILBERT SPACE and olny measurable when HILBERT ECLUDEIAN SPACE VECTOR INTERACTION is is Traced or Scaled into the RIEMANN METRIC then You get the Einstein-Ricci Metric TENSOR with the RICCI NEGATIVE curvature VANISHING into the Hausdroff measure BY THIS ROTATION gauges the
PARTICLE FIELDS VECTOR basis from this TRANSFORMATION FUNCTION And get the WAVE FUNCTION and when these FIELD VECTOR is Reflected into the LOCAL Gravitational force TENSOR using the RICC NEGATIVE CURVATURE FLOW you get Massless particles Gluons and photons particles Boson and its Intermediates elementary particles ELECTRON PROTONS
and NEUTRON thru Radioactive DECAY along with The 4 forces of Nature Of Time and 3 ADDITION DIMENSION OF SPACE and QUANTUM SPIN Being INTERGER and1/2 HALF INTERGER
TheMedia-Hacker I concur
@@FriendlyPerson-zb4gv As I understand it, one reason is that electromagnetic fields propagate at the speed of light, while entanglement is instantaneous over any distance. Also the propagation of electromagnetic fields involve photons (a boson field carrier "particle") and there is no such exchange of energy in entanglement.
@@evalsoftserver thx man thats a great explenation
Great. Thank you all...
It has been a long time. This is greatness.
This is a fantastic discussion. The single best on the topic I've seen.
The W.S.F. needs to happen more than once a year! 👍
what for- to say the same?
This was a spectacular lesson, I have absolutely no complaints, just sitting here watching this I some how feel like this is the most remarkable lesson I’ve came across. Very interesting, spoken well and in a way where us weaker minds can take a brief understanding.
Best part is I have listened to this three times and I’ve learned something new every time. Watching the graphics now and it definitely helps you comprehend better vs using this as a bed time story/car ride. I enjoy that they elaborate on Schrödinger’s Cat- the box model and TH-cam videos on this just don’t elaborate enough and this video just hits it with a nail!
So Very proud of this video and I have nothing to do with it!
Thank you, for sharing quantum mechanics to the public. I think, one day I might be able to wrap my head around it, but I think, 🤔 it's unlikely. However, I can take it in small doses, because, I'm really interested.
This was one of the better presentations I've seen bringing together the all the big concepts of QM and GR theory.
Most straightforward explanation I have seen yet!
Brian Greene does it again. He pretends to be the one in the panel of experts who does get it in his humble way so we can all feel better about being part of the subject and then he transposes everything the panel members say into something we can all understand. He can distill all of it for us. He has the unique ability to be the frame that holds the window we are trying to look through. I am no scientist nor am I an expert but Mr. Greene allows me in particular to enjoy being curious about all of this. Thanks again Brian Greene, I have enjoyed all of your publications - written and verbal. TW
David Wallace is really David Cross in disguise.
What a great video, explaining each and every step of double slit experiment. thanks to that moderator it is going inside of brain by step by step.
Excellent presentation combining graphics and comments by Excellent communicators on stage.
Thank you Brian! Also amazing panel! Can't wait to show this one to my Dad and have a lively discourse. :)
By definition, how could there be anything more interesting?
Well there could be something more interesting and there couldn not be, and there could be or could not be a more interesting thing. The real question is, are they going to play more futurama?
There’s an infinite amount of more interesting things
@@ryanyoung4184 like futurama
Walking throught the forest, watching the water fall as it hits its bottom, climbing the trail and reaching the top to look over autumn colored trees for as far as you can see, looking out a winter morning and just staring at the beauty of the snow, and lastly not believing people being fed info through ear mics acting like they have this great knowledge no one else has leading people away from the natural experience of the mind, trying to get you to forsake all you know to be true for the lie they have built all around you.
All I can say is "wow". I learned a lot about things that were just novelties in the past. The way I got to this video was following the thread about faith, God, and how science is teaching us more about the universe. Would love to hear your thoughts and speculations about that possible connection. Thanks Brian and team for being such a good translator of the hard science into an understandable story.
I see you are able to perceive what most cannot or rather refuse to observe (and experience). Much love
A Tale of Quantum Physics
When I retired a few years ago after forty some years as a physicist/scientist/engineer/college professor I decided it was time for me to develop a solid understanding of quantum physics, a.k.a. quantum mechanics. I mean how could I call myself a physicist if I didn’t know all there was to know about such an important subject. So over the past five years I spent a lot of time reading everything I could find online about QM.
I read about what the most brilliant scientists had to say, from Einstein’s comment “God doesn’t play dice” to Schroedinger’s schizophrenic cat. I read about the electron double slit experiment which gives wildly different results depending on whether the outcome is being measured or not. Some scientists even claim that just being seen by a human observer causes the outcome to switch. Then I read about Richard Feynman’s chromo electrodynamics many-path formulation where every electron has an equal probability of going in any direction . . . until a measurement chooses the observed path.
The credibility was stretched even further when I read that Murray Gel-man proposed that every particle was made up of even smaller components called quarks (which always occur in threes and are somehow part of ‘The Eight-Fold Way’); that David Dennison claimed that electrons, protons, neutrons, quarks, and just about every other atomic particle not only had spin (up or down), and Gel-Mann’s quarks came in three designer colors; red, blue and green. And I haven’t even brought up quantum entanglement; what Einstein called “spooky action at a distance.”
I finally realized that there was no way I would ever understand it all and fretted about this until I came across the words by Richard Feynman: “I think I can safely say that nobody understands quantum mechanics. If you think you understand quantum mechanics, then you don’t.” None of the “experts” really understood it either. I could go back to claiming I was a physicist!
But how could such situation happen? Well, each of the experts developed their own pet theory, but none of the hypothetical frameworks could hold together - be consistent with what we knew for sure. So the creative scientists invented whatever it took to make their theory work. Sometimes it was new (but unobserved) particles like quarks, or immeasurable properties they called spin, color, or an infinite number of multiple paths.
So my final conclusion was that quantum physics/mechanics is like the story of the king’s new clothes. Every scientist saw what they wanted to see, while the truth of it all was that the king was really naked.
You made one glaring mistake in this post. All cats are schizophrenic.
This is a very good video. It helps me understand quantum reality, which I did not really understand before.
If you understand quantum reality, then you don't understand it haha
haha Feyman said that out of his ass Guanqiao Wang

Yes! World Science festival is back again :-)
Fell asleep whilst watching TH-cam this came up wasn’t able to absorb the mind blowing content but Brian was there in a pub I was there too just listening to his distinct voice and manor
Finally i understand the explanation of when and were the time stops.
Wonderful to see eminent physicists humbly admitting what they don't know..and they speak in down-to-earth language to make novices like me understand. Brian Greene, an eminent physicist himself, acting like a novice, just because he is the anchor. Amazing people.
Welcome Back, World Science Festival.
Remember the introduction, if you can understand what we say, then you are a genius. That sounds like a con-artist.
@@jamesmooney5029 That was not the introduction. (if you mean the introduction to this whole thing, not a sentence someone said as a beginning of their argument, in which case ignore my comment.)
On the subject of parallel universes, for a better understanding, I like to think of time as a superposition itself. Besides videos and photographs (which serve as time measurements), we can never be truly sure about the past or the future. Only the exact moment in time, as we experience it, delivers us the current state of it.
In this way, parallel universes might not be so odd after all, as we experience only this moment from both 'quantum fields.' The rest is all plausible.
The particle is "here and there" whilst also being "here or there" because of the simulation
It's just the way the code is written so the program runs seamlessly; regardless of whether you're observing the particle or not.
what i find really interesting is that the interference pattern from the "particles" is perfectly described by the classical wave packet.
At 27.35 Brian Greene talks about the moment when you actually do the experiment and you find the electron being here or here or here.
The Question
no1 is: How do you find the electron being here or here?[don't you actually find traces of places it's been?]
no2: what method its used to see where the electron has been.. is it a mathematical equation or a physical observation before and after?
I have a question about Time Travel ...
If at some point in the future, If traveling back or ahead in time becomes possible, how does ones physical location fit into the mechanics of one's surroundings
I spent some good few minutes looking for a good long video too fall asleep too. Not even in a mean way I just want something to listen to while eating or doing something simple
Me too. I enjoy listening to these thought-provoking videos before nodding off. Trying to solve math problems in my head also has the same effect.
I usually go to math or science videos for that too. You can fall asleep to them but if you are up and alert they are interesting to watch until you do get sleepy
The theory of this program is that a very complicated subject can be explained to a lay audience via a committee. The only thing I learned by watching it is that this theory does not work. But, actually, to learn that is useful. So thank you.
This is exactly what I needed on a Sunday afternoon. So grateful to be able to understand what was discussed and appreciate the dedication of physicists through the years. The particalization of the wave is meant to prohibit the wave of connectivity with each other and our enviroment, which is how we evolved, as a social specjes This connection with everyone is harmonious and the introduction of the "ego" and the concept of "I", rather than, "we", prohibits this connection we've evolved with and limits us and allows us to be managed. When you work and earn money, that is the particalization of the wave. The digitization of the experience. The multidimensional expressed in a foreign, two dimensional "binary" code representation of consciousness and connectedness is suppressed by division, competition, concepts of "race", "us vs them",(such behavior perhaps served an evolutionary purpose and avoided introducing foreign pathogens to various tribes?), but they even describe it in the Book of Genesis. The serpent is "self awareness", and the concept of, "All this "we", what about "me?", is introduced and suddenly then they need clothes, Cain kills Able, everyone got wicked and started polluting the genetic purity of Homosapiens and Noah built his ark and God flushes the wicked away with the flood, and the rest is experienced as an invisible servitude burdened by foreign concepts and ideas perpetrated upon humanity as a means of control and the constant push to impose the digitization of our analog consciousness.
.....
You quack like a duck
You said a whole bunch of nothing.
A couple of years ago I tried a homemade double slit experiment. I used a cheap laser pointer and kitchen aluminum foil. I used a razor blade and a magnifying glass to cut the two slits as close to each other as I could.
At times I definitely saw more than two extremely faint stripes on the wall.
Mr. ‘t Hooft is fantastic.
Professor.
Heillo goodnight now 27/07/2019
He’s a hoot
As Hoof (and Whaley)indicated , entangled particles are only produced when two particles have initially been brought into intimate contact with one another . To ignore that, and simply accept the "spookiness" of QM entanglement mathematics as applied to those particles -- after they have then been separated --- looks a little blinkered .

Maybe it’s just my naïvety, but the idea that electrons are only in one place once we observe them says to me that our consciousness creates reality. In my mind, it reinforces the idea that the universe is filled with endless possibilities until we experience it for ourselves, at which point all of the other possibilities dissipate and all we’re left with is what is actually happening-what we call “reality.”
Their approach is misleading you
You're looking at it through a much more philosophical lens that the likes of George Berkeley might agree with you on. He put for the argument of Subjective Idealism which essentially takes a much more spiritual/mind oriented approach to describing reality. He actually makes his case in a famous argument between two ideologies called "Hylas VS Philonous" where he rationalizes empiricism to it's logical conclusion that there is no such thing as physical matter. There are only properties of the mind. I really enjoy this perspective of reality and think it's worth reading into if you're interested at all!
I couldn't agree with you more 👍🏾
This is EXACTLY what it is! You hit it SPOT ON!
> In my mind, it reinforces the idea that the universe is filled with endless possibilities until we experience it for ourselves, at which point all of the other possibilities dissipate.
Which is the same as them not existing at all - if there is a possibility that is never experienced, then that possibility may as well not exist.
To me, the whole theory falls apart by not defining what constitutes an 'observer'. Without that, the rest of it is meaningless.
Somehow, I find myself entangled in something, I don’t understand. Yet, at the same time, my brain feels entickled.
Remain frolic
