How wonderful to listen to an intellectual debate in which the participants truly discuss such deep ideas. Most media seems to be obsessed with getting people to argue or disagree - what this shows is the true strength of human intellect. It is beautiful to listen to these people - and to learn about such ideas. Incredible!

Another excellent discussion at the World Science Festival. It's these kinds of talks that make the internet so valuable.

I have this video several times. I never get tired of watching. Those are great scientists. Thanks for the world science festival for bringing this out.

Beethhoven being able to compose that kind of music whilst entirely deaf is like the ultimate artistic flex possible.

The fact almost all of these videos start with something to do with Einstein shows the impact of one man.

Wish I had the head for the higher sciences like these people, but at least I can watch and listen and still be amazed by them. A great watch.

I so admire Dr. Brian Greene’s humility and so enjoy the layman fashion in which he simplifies and imparts the intricate subjects he addresses and so successfully conveys. He’s my favourite Author. Do look up all of its books, which I highly recommend if you enjoy this lecture; I own and most cherish all of his books. This man is exceptionally brilliant, as is Dr. Michio Kaku, yet another favourite Author of mine.

Brian green’s expression and hand gesticulations were so convincing that if I didn’t have the volume up, I’d have thought he was describing where and how we could assess the 4th dimension

I love how the only real way to understand reality is to lose it, going beyond

I like Brian Greene A LOT more on stage like this than in a goofy documentary with silliness.

Brian, I love you for seeing that the glass is half full. Please, don't ever change in your optimism because truth will always be verifiable. Peace and infinite blessings, yishmirai.

I love the analogy of the dimensions and Beethoven’s Grosse Fuge Op 133! Just close your eyes and move with the music. You can almost feel them spinning around you. A perfect coupling.

Man I love this stuff. I never learned mathematics this high to understand the theories well, but the fabric of the universe with these extra dimensions seems to be like the physical basis of computer programming, the hardware containing the on/off switches, the basis for EVERYTHING we do with computers. Speech recognition, programming robot movement, watching youtube on my monitor, all goes back to the on/off switches, the ones and zeroes. The Almighty gave us the hardware of reality, the building blocks of all of our experience, and with our hands and minds we are able to program it and use it to learn about ourselves, where we are, what we are, and continue to grow. To me, the more we learn about the nature of reality, the more evidence there is of design and purpose. Btw I dont intend to turn this into a religious discussion, just sharing my personal opinion.

"One person's space is another person's time." I think he was late because someone took his parking spot.

I appreciate that these people have made their work intellectually accessible.

Best conversion to get a sense of how diverse reality is.

I've never been to Hyperspace, but I've heard you can get there with 50mg of N,N-DMT.

So glad Krauss (only non-string theorist) is here to spice things up.

This is just so good. Thank you for such a wonderful panel and sharing it. I'm so glad I stumbled across this tonight.

You all are on the right track, somehow I feel it's easier than the complicated processes that take place. Not that I can explain the simplicity either. When I was a teenager, 13, 14, my friends and I had a discussion about the after world. As we worked our way through beliefs, scripture and what not. I had a vision that seemed to come from GOD. And the way I explained it was that out there in the vast universe are different worlds similar to ours or even duplicates to some degree. As we pass on from this realm we are directed to another world or dimension. I'm forgetting something's from back then but thats the bulk of what we discussed. Of course the others had there own opinions and beliefs and I may have swayed a couple of them to mine. That's something I have held on to and reflect on over the years from time to time. Thank you, great video. Can never get enough of that subject. So much to discover and learn but so little time...

I love how it takes a medium smart guy to explain to kind of smart people what's very smart people are talking about. Thank you for the science Festival! It's amazing.

Watching all of these utube presentations of Quantum Mechanics, I seem to recall that one of the reasons that gravity exists and electro-magnetism is motion. But not just any motion, but rotation. It seems that whether the universe is expanding or not, within the various masses, there is rotation. It is notable that rotation in our universe is often counter clockwise, but it can also be clockwise (moons; planets). With some mention of the molten interiors of cores of planets, making these heated entities involved with both electro-magnetism and gravity. Not only does the earth revolve, our entire galaxie revolves, orbits or rotates. In the largest of senses, black holes are orbiting. In addition of the universe expanding and getting further away from one another, relative to at least one other entity, there is orbiting or revolution. So the question is that when one gets down into the various dimensions where "strings" of energy or matter exist and vibrate, what influence occurs within each string of energies/matter exerts a rotational force. So are these "floating" fields of energy or matter, or are they actually rotating in relationship to something? To anything? To one another? Thus is there anything in the smallest forces that tends to also "orbit?" AF

My problem with the "sheet" visualization for gravity has always been that the sheet isn't just under the space time and mass, its above and below and part of it, woven into and through. The gravity of all other objects is, sometimes miniscule, sometimes not, affecting all others. The "sheet" analogy doesn't really hold up if you think outside of "gravity makes things go down".

"A tree is to the universe as a string is to the atom" ~Brian That art was strange-looking although very cool because of the age. Can you imagine string theory being thought of like that one day,yeah that's crazy🤯

I just can't be grateful enough for you guys uploading these videos. They are coming with a near perfect timing into my life right now. Thank you for all your efforts.

Brian Greene....always doing an incredible task of breaking down complex material in physics so well that a kid can appreciate this knowledge

I never would have understood a word in this, if it wasn't for the mini concert segments. thank you so much.................

Flatland by Edwin A. Abbott is one of my all time favorite books. Really interesting and mind blowing.

Krauss rocks! 1:20:16 "30% dark matter & 70% almost dark energy...everything you see is irrelevant". I would love to see this panel after they tried DMT and broke through to hyperspace - that would be a stimulating conversation.

I find Brian Greene can put down any complex theory in layman's terms and that's why I find very captivating. Been following him for a while now

Bands of musicians are taken into war to make it more beautiful. These artists took my breath away. Music can open our minds as nothing else humans can compare.

This is absolutely wonderful. I love how science and art are given such equal weight in understanding our reality. Thank you for bringing us such quality content, I am so very grateful! :)

I am so glad this video has over a million views. This was very good and well explained. Lawrence Krauss makes me laugh because he is known for challenging everything (often times gets caught up in debates about does God exist or not) But he makes a valid point, we need experimental evidence. String Theory still is exactly that...a theory. In a way String theory is analogous to Plato's allegory of the cave in that the physicists are trying to explain detectable phenomena (Shadows on cave walls) like quarks, gluons, forces etc with a theory that tries to explain what is causing the phenomena. Problem is, string theory may end up working mathematically, but the theory may just be a representation of what actually exists, like the puppets casting the shadows in the allegorical cave, puppets which, are only caricatures of what truly exists outside of the cave. And we still don't know if the math truly implies 12 physical dimensions. The reality is that everything actually exists in the 3rd and 4th dimension (Time and Space). A point, a line, and a plane technically do NOT exist in the real world. If you were to draw , a point, a line, or a surface it is impossible to do without 3 dimensional space. Meaning a drawn line will always have a thickness and a depth, even if the line is only an atom deep and an atom wide, our representation of our invented mathematical models must exist in 3D. What we consider the first and second dimensions are imaginary in a sense, they do not exist in reality. So the mathematics that requires an 11 dimensional universe for string theory to work, could just end up being a hypothetical explanation that doesn't explain reality in its entirety. Perhaps the Unified Theory of everything is much simpler than what the 11th dimensional math suggests. But who knows at this point, I agree with Lawrence Krauss in that we need experimentation. Having to scale down to a factor of 1x10 ^15 power to describe or confirm vibrating strings seems pretty daunting though. Another thing we need to realize is Newton's laws of gravity and motion work perfectly at the human scale, proven time and time again. The math was solid for 100's of years until Einstein came along. His theory of relativity more accurately described the orbit of Mercury and the eclipse experiment proved his theory that the curving of spacetime bends light. It seems likely that newer mathematical models will come out that are even more accurate and precise beyond string theroy mathematics. The search for a unified theory of everything is such a profoundly interesting field of study and discovery. I would love to sit down and converse with some of these physicists, that would be epic. anyway awesome discussion, they all did a really good job of explaining this science so that it can easily be understood.

want to skip that violin part at 16:34 ? go to 21:10 :P

Excellent content once again.The mention of Scandinavian metal bands had me cheering like a good metal fanboy.

There's one thing I simply don't comprehend. You've done a really good job of explaining special relativity in a way that made sense so I'm hoping you can do the same for the concept of dimensions. How can a "dimension" be "small" or "curled up"? Isn't a dimension just a direction at right angles to all the other dimensions? How can a direction be "small" or "curled"? To me that sounds about as understandable as if you were to say left is green, right is big, forward is C#, down is beautiful. It just sounds like gobbledygook.

Great step to give knowledge and introduce science to youngsters like me and all I have learned a lot from these

I thought this was a really interesting discussion. Granted, i'm still a layperson when it comes to String Theory/ Hyperspace/ Quantum Physics, but I did think it was fascinating nonetheless. I found myself agreeing (at least partly) with Lawrence Krauss and Shamit Kachru. I didn't think Krauss needed to be so underhanded about his critique of String Theory, but I do agree that we need to exercise caution in placing too much hope into a theory that has had a great difficulty in being verified experimentally. Although like Shamit said, it could just be a matter of time.

Myself and other artist as well have viewed that science experiments have actually come to a temporary stopping point, mostly caused by their valiant attempt to prove string theory. We see it as not being solved in our life time. So many of us have moved on to working with trying to feel extra dimensions while doing our work. That is the ability to understand our world as we know it is a matrix mostly created by evolution of societies. Therefore, we try to set aside the matrix and work in the possible extra dimensions that likely exist according to science. Some folks have termed it the "awakening." Whatever it may be, a delusional experience or an ability to escape into other dimensions; we find it just as positive experience as science working to discover the unknowns. For it is and always was us artist that can better communicate reality to the general public. Our position is much the same as the scientist, that if we do not somehow get through to society very quickly, life on this planet will become impossible.

I'm glad that UKposts could bring that to me. Since I couldn't be there.

16:30: Greene is a showman par excellence.

Nothing like intelligent people! I could listen to them all day, especially my hero Neil!

"No good experimentalist listens to theorists, ever." This is honestly the best artistic advice I've heard in a while...

47:00 - Yes, time has to be involved in there as one of the dimensions, to get special relativity to work out right. Reference frames that differ in velocity with respect to one another "rotate the space and time dimensions" so that they get mixed together. So time has to be one of the "axes."

Wow, I've accidently stumbled across this channel and this is amazing. Thank you.

On a more serious note, it sounds like there is no hope whatsoever of doing experimental work at the energy levels required to reveal strings, so I make this suggestion instead: Begin by assuming that everything is some sort of fractal that self organized out of Planck sized particles. Such a fractal would have detail that might remain forever invisible due to its smallness, however it would also have emergent properties--large scale structures that the fractal tends to return to at ever growing sizes. Such emergent properties would effectively ECHO the smaller scales we can't see, and might allow confirmation of some theoretical conjectures. Great video. If you watch enough of this stuff, some of it sinks in.

Classical music and theoretical physics and presented by an incredible group of physicists and it has jokes in it, this must be heaven

I really like how Brian communicates and outlines his presentations. The tone, pace and dynamics in his speech convey the science beautifully. Green and Kaku are my favorite modern physicists. Thank you WSF.

This video gave me good vibrations ...

There some things in this life that I intimately understand...trying to comprehend a plane of existence I can not hope to physically interact with is not one of them. I still enjoy the fun of these theories and can't wait to see what we learn next

For some reason.. I'm addicted to these lectures.. I never new Science could be so entertaining🤌🏾👌🏾👍🏾 I didn't even know that I was interested in Science, until witnessing these lectures... keep it going.. Great Job 👍🏾 I love it..

Can’t believe my UKposts didn’t recommended these gems until I searched for the 4th dimension.

This has got to be one of the best videos on UKposts!

When I was a kid I would have the craziest dreams. I would say I feel like I went somewhere else in my sleep. I experienced sleep paralysis when I was a child (haven’t experienced it again as an adult.) when I experienced the sleep paralysis I thought it was because my soul (or astral body) wasn’t quite back in alignment with my physical body just right. Also when I would fall in my sleep (I’m sure everyone experiences that) I thought that was my soul or astral body leaving but because my physical body wasn’t quite asleep it would fall back into the body. I still believe our soul (or astral body) travels through dimensions in our sleep 😴 I believe our imagination is a lot stronger than most people think and we are creative beings.

this was sooo good, thank you 💛

Too think that there’s potentially another me in another world with events playing out practically similar to the one I’m in is literally crazy

reading the comments in this video make me wonder how we have been able to create technology and science. Amazing...

Great moderator. The host really sets the ceiling for the level of the conversation.

The Muon was discovered last month, and this is what we are talking about in 2015. Theoretical Physics is beautiful

Amazing ! Good job sir. A void can not exist but yet again if you zoom in into something , everything is a sphere or presented as one and there is void in between , or rather everything is a vibrating string and there is void in between , Void can not exist but here is void ... really smooth. Atomism at it's best , all hail the great axioms .

I feel enlighten by this video😶😯

Thank you fo a terrific presentation and talk. It was awe inspiring and easy to understand. And the string quartet was beautiful.

When we are looking with the Mind's eye in deep meditation, we are capable of seeing into many dimensions as they are all contained within as well as around us.

Hard wired to "think" things are beautiful

I'd love an 8ish hour conversation with about 10-20 participants.

Just returned from a dmt trip, and saw at least 7 of 'em. ;)

I watch a ton of these and this one is better than average because it speaks to the pain I always have, which is that sense that we haven’t had a breakthrough since quantum mechanics was proven (in terms of gut) and may not for decades or perhaps ever, and how does that affect enthusiasm for popularizing and studying physics.

Philosopher/teacher Alan Watts knew aobut these "strings" in the 1960's but he called them "waveacals" (sp?).

Very interesting indeed !! We are obliged to look for "things" beyond the established. How sure we are that there is an other spatial 4th dimension in our lives for real ? Perhaps there is such a dimension but, I think that we don't live in it either. If a tree (made by nature) lives in some other unknown spatial dimension beyond our senses (a 4D tree) then, if we saw it (with a chainsaw), it shouldn't fall! In the flatland, the residents couldn't do much either to influence a 3D object which touches or intersects their flat country ! To my opinion gravity is the 4th cosmos spatial dimension (not of course in the Newtonian sense)! ! Length, width and height means something out there but ... density is the real cause of the three-dimensional "empty" space curvature to a 4th dimension! Each object (and not only the objects) has its own density and thus acquires its own gravitational field. This energy field actually extends the three standard dimensions and surrounds any object. Our universe is characterized by constant motion and this is not the result of some time factor but of gravity. In reality, if you saw the tree , it will fall in the "4th dimension" of the planet and any other (free) falling object acquires the same acceleration within the same gravitational field! Good luck in science !! We really need it..

Picasso was really trying to depict the subject from different angles on the same canvas. So he was going for 3 dimensions. However, Marcel Duchamp in "Nude descending a staircase" went for the subject both from different angles and at different moments in time. This was genuine 4d, with time as the fourth dimension.

MC Escher understood the eloquent and dynamic tesolations of space which the vibrations of music in the air around us and the hidden choreography of our molecules gracefully folding and unfolding within us only hint at...

18:20 I just imagined Mickey Mouse going off with the magic spells

How pleasant to find somethng like this on youtube, that gives me a break from the selfie-twerking, and top ten lists, that seem to fill every channel of mindless garbage.

Basically you can conclude that a dimension is constituted by the ability to measure it as well as show it has some sort of relationship with the other dimensions....For example we all know space is made up of 3 dimensions that we can already see. But then there hidden dimensions that we know must exist even though we can't see it (because we can measure them and we know they are inter-related). Examples of these are "Time" (we measure time in different units like seconds, minutes..etc), "Movement" (we measure movement by speed), "States" (solid, liquid, gas), and "Temperature" (Celcius, Fahrenheit). Time and movement are inter-related because the faster and object moves through space, the less amount of time it takes. States and Temperature are inter-related because the hotter the space the more gas the state and the colder the space the more solid is the state. Pretty much in order for a hidden dimension to exist, it needs to have an effect in the space realm.

I appreciate you exist in a higher understanding

@10:30 Humans on Earth Surface represents same example, we see earth flat in human scale but it is curvered when seen from space.

the sound of silence, a deeper dimension

Awesone channel, awesome speakers, love this guy.

its 3 in the morning how did I get here....i barely passed general math classes

Thank you. So perfect. Art & Science.

Wonderfull to listen to these ways of trying to communicate in different ways of the dimensions of reality. I always wondered about experience because when you really open your ways of being aware - it seems to mexthat experience is multidimensional. We can experience any phenomena from unlimited perspectives - ans that is a basic experimental way in working with art --💜

Always wondered if the curvature gravity causes in spacetime like water in an ocean is what is causing the expansion of the universe to move faster. The more space expands and stretches the less the curvature. Like the universe reacting to gravity trying to right itself and smooth out curves. Or like a blackhole creates such a crazy stretch in space the it acts like a cause and triggers all of space in reaction to stretch. The more black holes pulling on spacetime in the universe as time goes on the greater the reaction to the universes spacetime as a whole causing space to expand and stretch everywhere. So the weight of a black hole stretches space thereby causing expansion of the universe as a reaction to the black hole causing stretching from gravity. The more gravity comes together in bigger structures stretching space more and more the faster it expands as a whole.a black hole similarly to throwing a huge rock in the water causes displacement which is what we see as the expansion of space. Instead of the black hole falling down into infinity it causes space as a whole to expand and stretch everywhere from the strain it puts on the fabric of spacetime

This IS the reason the internet was made! Beautiful!

I fell asleep while this was on, and I dreamt that I was on a bus having this conversation with Brian.

To me, hyperspace is just a button on a video game cabinet that sends your ship to a random point (or causes it to blow up).

What a time for my synchronicity to kick in 33:50 I thought what's up with his jacket at the same instant he said "jacket."

Amazing video thank you!☺️👏🏼💫

We need more Richard Feynmans. We need more brilliant born communicators with a passion for education who realise just how important it is to get out in the world and bridge the gap between the ivory towers of academic scientific research and the bulk of society who are frequently stumbling around in the dark feeding on the small crumbs of meaning we can glean when we don't speak the language of mathematics or theoretical physics. See, in the darkness, people are susceptible to any light offered them - and when it's organised religion that holds the torches in their gathering places on every street corner, promising easy answers and ultimates truths... people grasp at that. What we need are science centres near every church, mosque and synagogue. We need alternative, accessible places for people to come and listen and share and learn and find some damn light and hope in reality and the wonder of science, rather than the tall theological tales of institutions chiefly designed to stifle thought and imagination and keep the masses in check, as well as lining their own purses. You can argue that there's no really effective way to combat the evils of religious fundamentalism, and maybe you're right, but surely the problem begins with apparently inoffensive moderate religion. Once you've sanctified that you've laid the poisoned foundations for all the madness that can follow. Scientists have to take some responsibility in our collective future as a species. It's not enough to be doing wonderful research and formulating brilliant ideas in a comfortable academic atmosphere of mutual admiration - more of them need to be out in the world on the ground getting their hands dirty, making sure that people understand the progress that's being made. If not, maybe one day they'll stumble on that unified theory of everything but realise there's nothing left of humanity to appreciate it.

The more we learn the more it looks like we are in a program, only here threw an energy that we can't see or tell where these energy's are comming from.

I would have liked to see this in 1999, when I was working on particle physics. :D Thanks for sharing.

Moderator was solid - lets everyone speak but also controls the pace well etc. Panel experts were great too

Seeing that sheet music made me feel dumber than the entire opening lecture.

Original Comment - (Why is time considered to be the fourth dimension? It seems like it should be the first; thinking in terms of conventional theory, even a unidimensional construct can't exist unless it exists within a framework that allows it to exist from moment to moment. Coordinates become meaningless outside of the context of time...) Today, November 5, 2021 Welcome back. This is a (so-far) six-year long conversation that has barely begun, unless one of you has uncovered "the answer" (and no, "42" is PROBABLY not the correct one). The thing is, I have learned a crapload about this topic in the last six years, and accomplished...nothing. Such is research. Just to clarify; I need a place to start a mathematical model for (attempting to) describe or experiment with certain of the more challenging conundrums in physics. This model is, and will be no more and no less "interesting", "useful", or "groundbreaking" than any other, and in fact, will likely result in nonsense like most others (string theory). It is also not meant to "disprove Einstein", or any other established science having solid merit (although I do have some particular issues with special relativity.) So far over the past six years, I have built-up mathematical models that broke immediately due to comments from this very forum, because of, you know, "common sense" which is not one of my strengths. I built 7 that were just crap, two others that had promise, and then turned to crap, and fascinating one that's still waiting to be fleshed out, requiring some supercomputer time before being proven to be crap, and then flushed. Why? Because I AM one of more than a million chimpanzees attempting to randomly generate Shakespeare, so maybe one day I'll get a few characters right. And, I have found that "crowdsourcing" visitors here is saving a lot of otherwise wasted time. So, when building a universe, where does one start? Launching any project has prerequisites; so what are mine? Well, I need a PLACE in which to build it, and I need sufficient TIME to build it. But...will I need to first carve-out time in which to locate a place? It would seem so, placing TIME firmly in the first slot; but then again, TIME only exists when there is a MATERIAL change, which implies that MATTER takes the first slot, but then again, MATTER must exist within sufficiently formatted SPACE, which has to contain the MATTER over a certain duration of TIME, but SPACE outside of the context of TIME and MATTER is meaningless to begin with. It's easy to understand why the singularity got all worked-up and just went "BANG!" - getting the universe started is like working for the government; I would have exploded also...

I kept waiting to see if they would get into the actual subject of the electric universe. But maybe some of that would have been in the next hour if there had been one. Haha 😂 I loved it, when I tell people I believe in the multi string theory, it's hard for me, as a lay person, to explain what I mean. But this does a wonderful job of it and so I'll save it as reference to such inquiries.

There's an episode of Futurama that relates to this subject. It's called 4-D Blacktop.

when he said Plato, I thought he said play-dough

Wow! this was an excellent presentation, so much so, it made it easy to really comprehend to a non scientic minded person as myself.

I love this stuff. This is 5 yrs old now. Until I get a chance to search, does anyone know~ do they still have this- The World Science Festival/ looking for certain people? I.e. like comment below, "enthusiastic translation ambassadors", etc? Great knowledge, so worth learning :-)

Calabi - Yau geometry is incredibly fascinating.
