Way above my brain capacity to deal with the subject but still able to be totally mesmerized by someone able to see and understand time clearly... Truly amazing. 🙏
While I sometimes struggle a little to understand the experts being interviewed on this channel, for the first time I have to admit that I have not the faintest idea what this chap was talking about. What I did like was the comment, after he somehow twisted his arm through 720 degrees, "You've done that before"! 😁
@@RobYoung74 Just because you don't understand E8 lattice mathematics, as a potential predictive model, doesn't make it gobbledygook. Maybe you'd be better to stick with Sabine's channel.
This was easily the funniest conversation on Closer to Truth in recorded history. I loved it so much. I am going to go off and have a good look at this. Imagine if this is tied together! Sometimes, however, I have a hard time imagining that there aren't still plenty of fundamentals that we have no idea about, and that is what makes a unifying theory still seem slightly premature.
This theory, adding spin interactions, finally brings time into a conceptional reality for me. I think this makes time an emergent phenomenon, not fundamental.
I really wish you guys would put in the description or somewhere in the video when these interviews were filmed. This is obviously at least 10 years old, which is fine, but a lot of these videos seem to be presented as cutting edge theories when many have already been proven years ago (like this one) very unlikely to be correct. I'm not even sure if Garrett is still working on this theory anymore. It would be great if you could give us an ACTUAL description in the description. Thanks
Time is easy, it's always now. The eternal ever-present moment of now. You can dilate it, you can compress it, but it is always now. Singular in its existence. You cannot exist outside of the moment of now, you are the moment of now. It is in fact the only constant.
So, now is relative to the observer. We can accept that. The bigger idea is that we live in the eternal now. From the beginning to the end of existence we live in an eternal now. One remembers past nows and anticipates future now’s. They are all real and all exist simultaneously.
@ronhudson3730 For practical purposes, of course you are right, friend.. Still, SOME might argue that is the metaphorical equivalent of sticking your head in the sand.. Oddly, it is the prevailing view that even a single person does not interact with ANY conception of the word NOW (a misnomer), partially but not only, because of the conduction speed of nerve signals through the body and brain.. Such considerations may seem trivial, especially given our SENSATION of the smooth continuity of awareness, but from a scientific perspective, it certainly isn't.. One humble opinion..
Easy to understand that past and future do not exist but a little trickier to grasp that neither is there a now. What exists are things moving and our thoughts about them and our thoughts consist of the complex patterned movements of a host of things.
This is truly fascinating, and I'm doing my best to grasp the concepts being discussed. Garrett's demonstration to illustrate spin and particle orientation is incredibly intuitive. The idea of attaching a clock to the particle to help explain time's role in this context is a clever realization. As particles move through the spacetime manifold, they also move in time depending on their speed, which is a concept that's challenging to put into words but seems essential to understanding the intricacies of quantum behavior. I'm particularly intrigued by the relationship between spin and quantum field theory. The Dirac belt trick and the notion of holding an object to convey spin and degrees of freedom for different particles are captivating. It appears that these particles are intrinsically connected to spacetime itself, and their movements are subject to unique restrictions, which is reflected in their spins. For instance, photons with a spin of 1 can be likened to rotating a card 360 degrees to return to its original orientation, while electrons with a spin of 1/2 are connected by tendrils or fibers, which limits their movement. It's intriguing to consider that the universe seems to maintain conservation laws even in rotational symmetries, leading to the observed spin behaviors. Exploring these concepts, particularly through the lens of degrees of freedom for rotation, can provide a more intuitive understanding of quantum behavior. I share your enthusiasm for the potential implications of these insights, and I hope that we're moving in the right direction toward a theory of everything. Achieving such a theory could indeed open up numerous opportunities in science and technology, advancing our understanding of the universe in profound ways.
expansion of space (present) by electromagnetic field that measures particles from quantum probabilities? particles develop mass which increase time below speed of light?
Spacetime frame at rest - relative to what? To avoid causality-breaking CTCs with a Warpdrive, it is necessary to have a universal rest frame. Is that what he's saying?
Relative to itself. No universal "backdrop". The only thing static and universal would be geometry itself. At rest would mean, either no transformations, or that the transformations are aligned. Because you wouldn't be able to tell the difference.
@@strings41 I don't disagree with you but the point I was making was that that time (or motion) is only relative to a point of view, or having a position from which things can be measured. If you don't have a viewpoint (as in a consciousness) from which something can be measured then what happens to measurement?
Having another candidate for the flow of time apart from entropy is something that excites me. The theory seems far from being completely baked yet though. But things like these give hope. I wish Lisi and his collaborators all the best for the future!
Time is the fabric of the universe. Time is the energy that gives things the ability to emerge and exist. Everything emerges from Time. When you asked the question how long you were asking about an aspect of time. Duration. Length of time! The redundancy of your question answers itself. Time is the answer for everything.
I don't have the background to conceptualize this theory but the mystery of time is of great interest to me and I like listening to the the theories about it. I agree with scientists who suggest it's probably not fundamental. Illusive as it is, I do think its true nature will be uncovered someday.
Fundamental? Someday? You really don’t understand time do you? Let us help you. Time is fundamental. We do not experience anything fundamental without time. Time is the fabric of the universe. Everything forms through time. Time equals energy. For example, you said someday. We do not experience day without our star the sun. When you said day you were calculating time by the motion of the Earth orbiting our star, the sun. No star no day. When we see our star, the sun, we are seen time in action. We experience time through our star the sun. We experience time every day! This video is pseudoscience. Read more nonfiction. Dictionary. Encyclopedia. Thesaurus.

Because an observer in a different frame sees a moving object get shorter doesn't mean the object actually got shorter. An observer moving with the object can measure that the object did not get shorter despite what the the person in the other frame sees.

@@David.C.Velasquez: Lisi calls it his "theory of everything" and it's known as E8 Theory. In what way do you think 0-by-1's reply misused the word "theory?" It looks like E8 Theory was an interesting math exercise, but it appears to have several intractable problems and has been heavily criticized by other physicists. It's a good bet, though, that its actual problems are unrelated to 0-by-1's motivation for calling it crazy.
When he says there are other areas of his "theory" that is not as confident about, it makes me think of the physicists who want to get away from being dependent on using the standard model to describe everything. It seems like the real problems with his theoretical theory might simply be where he hasn't found a description that can depart from the standard model. I'm pretty sure I understood the smallest part of his description, but that is the sort of impression I get, and I wonder how magical/fuzzy the math is when assigning numbered values through the higgs field functions.

I believe so. Try to imagine scale as a 4th spatial dimension, with associated time dilation. Expansion and contraction, being equivalent to translation in this case. Addressing 0-by-1 yardstick analogy, as a thought experiment... You measure the speed of light in comparison to the yardstick, then 'expand' to the size of the galaxy, for instance. Now re-measure the speed of light, with regards to your also expanded yardstick, and with much longer wavelength light, which, from your perspective will have blue shifted to appear as the same wavelength used initially, as in your frame of reference time will have dilated such that the same lightspeed value is measured.
That guy has no clue what he was talking about. First all there is no way one can explain time before describing the notion of real and imaginary time as Hawking did.
I had to punt when he did not specify "at rest with respect to what?" There is no absolute standard of rest. So I guess he's saying that different rotations are happening in different moving reference systems, which makes no sense to me. Note that the "rotation" of the time axis in one system relative to that of a differently moving system is considered a "pseudo-rotation", and even that is a very specific rotation that has nothing to do with particles interacting. And yet he does seem to have some credentials.
An explanation of the Video with background: Unraveling Time: Garrett Lisi’s E8 Theory of Everything Time is an ever-present facet of our daily lives, yet its true nature remains one of the most profound mysteries in physics. While we intuitively grasp the passage of seconds, minutes, and hours, physicists delve deeper, seeking to understand time’s fundamental role in the universe’s intricate tapestry. Among the theorists tackling this enigma is Garrett Lisi, whose ambitious E8 Theory of Everything proposes a novel way to explain time alongside the other fundamental forces and particles that constitute reality. # The Quest for a Unified Theory The Standard Model of particle physics elegantly describes three of the four fundamental forces-electromagnetism, the weak nuclear force, and the strong nuclear force-and classifies all known elementary particles. However, it leaves gravity out of the equation, prompting the ongoing search for a unifying framework that seamlessly integrates gravity with the other forces. Enter Garrett Lisi and his E8 Theory, which ambitiously aims to achieve this unification using the mathematical structure of the E8 Lie group. # Symmetry Breaking: The Birth of Time At the heart of Lisi’s theory lies the concept of symmetry breaking, a fundamental process where symmetrical properties of a system are disrupted, leading to distinct characteristics. In the Standard Model, symmetry breaking explains how particles acquire mass through interactions with the Higgs field. Lisi extends this idea, suggesting that time itself emerges from symmetry breaking within the E8 framework. In Lisi’s model, the universe is envisioned as a four-dimensional fabric with the E8 group-a highly symmetrical, 248-dimensional geometric structure-superimposed upon it. This Lie group, comprising 248 circles, each represents a different elementary particle, such as electrons or quarks. The intricate twisting and interaction of these circles across the fabric give rise to the diverse particles observed in nature. # The Geometry of E8 and Particle Interactions To visualize this, imagine the E8 group as a complex, multi-dimensional lattice where each circle symbolizes a particle. The way these circles twist and interact determines the properties and behaviors of the particles they represent. When multiple particles converge at a point, the geometry becomes increasingly complex, reflecting the interactions that occur in particle physics. Lie groups-mathematical structures that describe continuous symmetries, such as rotations-are central to this framework. In three-dimensional space, for instance, an object can be rotated in three perpendicular planes, corresponding to the three spatial dimensions. Lisi draws an analogy between these geometric rotations and particle interactions: just as sequential rotations can produce new orientations, particles interact and transform according to the symmetries dictated by the E8 group. # Time Emerges from Twisting Geometry So, how does time arise from this intricate geometric dance? Lisi explains that curvature within the E8 geometry plays a pivotal role. Curvature, in this context, refers to how the geometry bends or twists within space-time. If the geometry remains static, the curvature is zero, implying no change-akin to time standing still. However, when the E8 group twists consistently in a specific direction across the entire space-time fabric, the curvature remains zero, but the geometry possesses a non-zero connection. This uniform twisting results in symmetry breaking, where the original symmetrical properties of the E8 group are disrupted. The direction of this twist effectively defines the flow of time, distinguishing it from the spatial dimensions and linking it to the behavior of fundamental forces. This process not only differentiates time from space but also intertwines it with the Higgs field, which imparts mass to particles. By doing so, Lisi's theory elegantly connects the emergence of time with the properties of particles and forces, suggesting that they all stem from the same underlying geometric structure. # Connecting to Special Relativity and Cosmology Lisi’s theory doesn’t stop at explaining time’s emergence; it also integrates principles from special relativity. According to special relativity, as objects move, they experience time dilation, where a moving clock ticks slower compared to a stationary one. Lisi incorporates this by using a larger Lie group, Spin(3,1), which accounts for three spatial dimensions and one temporal dimension. The twisting of this group over space-time defines how time flows, allowing the theory to predict which frames of reference are at rest. Moreover, Lisi’s E8 theory aligns with cosmological observations. It naturally leads to a space-time model known as de Sitter space, which incorporates a positive cosmological constant corresponding to dark energy-the mysterious force driving the universe’s accelerated expansion. By linking dark energy to the Higgs field within the E8 framework, Lisi offers a unified explanation that bridges particle physics and cosmology. # The Road Ahead: Challenges and Implications While Lisi expresses strong confidence in certain aspects of his E8 theory-particularly its geometric explanation of time and its compatibility with de Sitter space-he acknowledges that other components of the theory require further validation. The integration of gravity with the Standard Model remains a formidable challenge, and the scientific community continues to scrutinize and test the predictions of the E8 framework. Garrett Lisi’s E8 Theory of Everything represents a bold and innovative approach to unifying the fundamental forces and particles of the universe. By proposing that time emerges from the twisting geometry of a high-dimensional Lie group, Lisi offers a fresh perspective on one of physics’ most enduring mysteries. Whether his theory withstands the rigors of experimental validation remains to be seen, but its elegant synthesis of geometry, symmetry breaking, and cosmological observations makes it a fascinating subject of study in the quest to understand the true nature of reality. # Further Exploration For those intrigued by Garrett Lisi’s E8 Theory and the intricate interplay of geometry and physics, the following resources offer deeper insights: Garrett Lisi’s Publications: - An Exceptionally Simple Theory of Everything (2007): Lisi’s seminal paper introducing the E8 Theory. - E8 Theory and Particle Physics (2010): An expanded exploration of E8’s role in describing particle interactions. - "Quantum Gravity and the Standard Model" by Garrett Lisi (2012): A detailed account of his attempts to unify gravity with the Standard Model.
Garrett's E8 theory should not be ignored.. That being said, to ME, it almost sounds hallucinogenic.. It seems impossible to imagine a mathmatical "object" like the E8 lie group physically existing and able to create everything by changing/moving/twisting without the prior existence of time enabling such actions.. VERY possibly, I'm just ignorant here. Maybe someone can clarify..
@@Bill..N No time, no space. Only illusions, possibilities, potentials, math relations, interactions networks with notdeteministic links between, just like one rotation can be viewed as two others in different combinations, or like nothing can be sum of somethings with opposite sign. Well, thats all.
@xtratub I can't see that perspective at all, friend.. The universe appears to be a very real PHYSICAL construct.. To say it is merely an illusion, well, that just flies in the face of our BEST current theories.. It sounds like an extraordinary claim with NO evidence at all to support it.. No?
Lisi says he is extremely confident about his result regarding the time aspect of his theory. Unfortunately for him, I can assure you that what he's saying is nothing more than a mathematical exercise without any relation to reality. For instance, he talks of De Sitter space, spacetime, and length contraction. However, none of these things exist in reality. It is nothing more than fancy mathematics, without any relation to real physics. So this all doesn't give any insight into the concept of time 😞
@@peterdamen2161 Ah yes, my bad. I'm sorry for not recognising your genius. I'm humbled by your very presence. I look forward to reading your unified theory of everything. Please accept me sincere apologies, your majesty.
FYI, I thought the geometric transformation aspect of his explanation of time was incredibly insightful. But you need to have an understanding of higher dimensions in order to join the dots.
A time tracking device, a clock, is not time. Such a tracker is subject to internal and external physical influences such as speed, the force of gravity and the lack thereof, quantum field and so forth. When the time tracker is impacted so as to lose its internal calibration, it simply malfunctions resulting into a speeding up or slowing down in its time tracking system. Using a physical device as time itself is misleading and incorrect.
Imagine a pencil lying down on a table. This is very symmetrical state for the pencil. But then consciousness breaks the symmetry of a pencil and start drawing. That symmetry breaking is consciousness. Particles don't want to construct a cell, but consciousness is forcing them to construct cells, organisms , societies etc. Consciousness is what fights against "laws of physics" . Physics of body want just lie on the bed, but consciousness is forcing body to get up and do something. Also consciousness is that force, that works against gravity. Birds, planes, spaceships - all are constructions of consciousness. So real anti-gravity is consciousness
@@ral1020 Also, imagine the following picture: make creatures, including people, invisible in your imagination. This picture is what I call a "strange planet". So: bicycles drive by themselves, cars drive by themselves, swings swing by themselves, doors open and close by themselves, spoons and forks fly, beds make themselves, complex structures assemble by themselves, stones melt and structure themselves into airplanes, ships, rockets, cars and other complex shapes. Also, skyscrapers are built by themselves, higher and higher, cities appear out of nowhere. Strange planet. A kind of evolving field that seems to be divided only if you are inside and part of this field. But if you see this field, imagining people invisible, then very strange things will begin to happen. It's as if some spirit or spirits are living on the planet. I think that this spirit is consciousness. Something invisible that causes everything to structure itself and behave contrary to the laws of physics. A certain field that permeates everything.
@@johnyaxon__ I like your examples. I do believe that consciousness is fundamental. Here's a quote from Max Planck: "I regard consciousness as fundamental.

I'm not sure whether what he was saying was that for any point in the universe there is a single rest frame predicted by his theory, or whether he was saying that a concept of relative rest frames emerges from his theory. I looked up an article he wrote on the theory, and it's not clarified there either.

When he says he gets time out of the symmetry breaking, does this mean he also gets classical newtonian gravity out of it there? I liked his story about special relativity as a perspective (like projective geometry, but a rotation instead), starting to like this theory this way.
Advances in science often simplify our understanding of phenomena. We know time is complicated, but using a Lie group? Looks like someone is trying to use epicycles again...

oh, wow, cool. Dimensions are perpendicular, making rotations in the highest dimension orthogonal to the lower dimensions in a reference frame not rotating in the time direction compared to the observer frame.

You were not supposed to. That shows you have common sense. What he was saying is unintelligible. The theory of everything it’s time. Time is the energy that connects relativity, gravity, and the quantum. The most obvious example that the pseudo scientist don’t mention is our star the sun. Our star, the sun is the reason for the elements on the periodic table. For example, we are our star. We experience time through our star the sun. The sun, our star is what time looks like in action.

Pseudoscientists, misconstrue, science and provide misleading information, pseudo scientist provide manipulated data. Time is everything and everything is time. Time produces energy. The universe form through time. There is no beginning without time. The atom is not filled with mostly empty space. The atom is filled with time.

I've encountered this before and it's quite appealing but I still don't get it. If someone were to ask me, I couldn't explain it to them at all. From what I've experienced, once you hit 'lie groups' it seems to go off into the woods. I haven't seen an explanation that works for me yet.
I imagine even if the theory was correct, it would have to involve some concepts that are at the limit of human cognition. You are an ant trying to model reality itself. I don't think we could fully grasp if even if we someday bump into it.

Trying to follow this geometric explainer for ostensibly all of physics as we know it is breaking my mind. I find Garrett's conviction compelling, but the complexity of this theory violates my sense that the universe just can't be that geometrically complicated and interactive. I note with some disappointment that Garrett was not asked a very simple but CRITICAL question. Does this theory make predictions that are testable??? An unusual failure in an otherwise rock-solid series.
This is called "over-engineering" - it's rampant in software dev too. I typically prefer a solution that *simplifies* in a straightforward, easily understandable way. Lie groups... circles... he involves far too many abstractions to explain basic ideas like an object rotating. I could rotate 2 of the rows of a Rubik's cube one way, and the other row the opposite way, but that doesn't mean "time is moving forward and backward" lol, there's nothing about that that's the case. That's the problem with casting all this into 3D geometry. There is no objective "arrow of time", space and time are relative to an observer. Even the order of events is different for different observers (example: 2 stars burn out simultaneously, being nearer to 1 or the other makes 1 star burn out before the other because light travels at a constant rate). No 1 vantage point is "correct" or more true than the others. The very concept of order of events is not absolute, it depends on where you are, how fast you're going, etc. Same is true of space, mass, size... how much mass something has directly relates to its speed etc. Special Relativity is essentially an explanation of how speed affects mass, time and space - that's already amazing.
I read somewhere that humans at some point in their life can only abstract in terms of their already existing knowledge, and lack the ability to realize it, while vehemently denying it. I'd say it's plausible that if we are to explain everything in the Universe to the smallest degree, we would be able to catch a glimpse of it through mathematics, to intuit it in a way, but not fully grasp it, otherwise we'd have to be all-knowing beings. If the math works for his model, which I'm not sure it does, visualizing it is a matter of subjectivity.
@@andreicristian9575 Well said. We can't jump to a totally unknown concept, we have to bridge the known with the unknown using analogies. Except maybe in dreams or psychedelia where you can experience a foreign/unknown but it's always so fleeting and you immediately forget, without concepts to cling to. It slips through. Given the nature of the universe, I don't think its entirety can be fully grasped in a single concept - you have to give up some truths to realize others. So anything we say the universe "is", is also "not" from many other perspectives. We can only speak of it in non-precise terms - to have precise terms is to take 1 vantage point or other, some relative frame of reference.
I wonder why this was re-posted after it was disproven in 2010. Distler, J., Garibaldi, S. There is No “Theory of Everything” Inside E8 . Commun. Math. Phys. 298, 419-436 (2010). Still an interesting idea I guess :)
*"He’s come up with A Theory of Everything but he’s still bald."* ... Now, see? That's already covered in "Multiverse Theory!" In another universe there's a version of him that's a hippie.
Sounds coherent but how congruent is it with measured results - after the fact measurement? Theory is wonderful if its coherency matches Nature with fine-tuned congruency. Don't be fooled, however, if coherency and congruency match really well. Ptolemy had a model of the revolution of bodies "around the Earth". His complex theory of cycles and epicycles and "efferents" was accepted till Copernicus and Kepler thought of something "simpler". Don't get me wrong, complexity isn't automatically disqualifying. The assumptions behind the theory: the rules, however, matter. Coherency and congruency do not mean reality. After all no theory of biological digestion can ever "explain" the urge called hunger. There is something more to reality, I think, than coherency and congruency can "dream of". In other words, just as no thought can fill your belly, so no thought can stop time. A donut 🍩 may postpone hunger, just as a clock ⏰️ may be behind time. If you solved time would you also be able to solve eating? According to DC's Flash you wouldn't.
That is the most stupid so-called scientific discussion I’ve ever heard. Stop misleading ordinary individuals... there is no way one can explain time without first explaining the difference between the notion of imaginary and real time.
Not being a mathematician, I don't fully understand Lisi's connection of Lie groups with time. Lisi seems confident about his ToE, but his overreliance on complexity and abstraction leaves me skeptical. Although my ToE also includes mathematics, it doesn't require a +160 IQ to understand how it works, nor should any all-encompassing explanation surrounding "Existence" do so. The biggest problem with most ToE's is trying to explain the *"Everything"* part solely by way mathematics when that's just one piece of a much larger puzzle. Another problem is trying to attach "time" to something other than what it is (like space, dimensions, and now "Lie groups"). ... Time is simply a "unit of measure" and nothing more, ... and what it measures is "change."
Yes, but there is something more to it. Change seems to have a preference when it comes to direction (towards chaos), for the entire Universe, not just me and you. Change also slows down when you observe it moving very fast.

Well this is certainly good news! Oh wait actually I have no idea what any of this means
This means that Time is an emergent property and that asking us "what there was before the big bang" is a stupid question.
This was easily the funniest conversation on Closer to Truth in recorded history. I loved it so much. I am going to go off and have a good look at this.
Imagine if this is tied together! Sometimes, however, I have a hard time imagining that there aren't still plenty of fundamentals that we have no idea about, and that is what makes a unifying theory still seem slightly premature.
This theory, adding spin interactions, finally brings time into a conceptional reality for me. I think this makes time an emergent phenomenon, not fundamental.
Hawking came to such a view of time and the laws of physics, according to his collaborator Thomas Hertog (in On the Origin of Time)
Time is what clocks measure. Nothing more, nothing less. Choose your clock wisely!
@@ToddDesiato Nothing deeper than that?
@@Bill..N Nope, nothing. Every atom is its own clock and keeps time at its own rate, depending only on the gravitational potential it interacts with.

I really wish you guys would put in the description or somewhere in the video when these interviews were filmed. This is obviously at least 10 years old, which is fine, but a lot of these videos seem to be presented as cutting edge theories when many have already been proven years ago (like this one) very unlikely to be correct. I'm not even sure if Garrett is still working on this theory anymore. It would be great if you could give us an ACTUAL description in the description. Thanks
Time is easy, it's always now. The eternal ever-present moment of now. You can dilate it, you can compress it, but it is always now. Singular in its existence. You cannot exist outside of the moment of now, you are the moment of now. It is in fact the only constant.
Have you considered the implications of Einsteins' insight that there are no simultaneous NOWS for any observers?
So, now is relative to the observer. We can accept that. The bigger idea is that we live in the eternal now. From the beginning to the end of existence we live in an eternal now. One remembers past nows and anticipates future now’s. They are all real and all exist simultaneously.
@ronhudson3730 For practical purposes, of course you are right, friend.. Still, SOME might argue that is the metaphorical equivalent of sticking your head in the sand.. Oddly, it is the prevailing view that even a single person does not interact with ANY conception of the word NOW (a misnomer), partially but not only, because of the conduction speed of nerve signals through the body and brain.. Such considerations may seem trivial, especially given our SENSATION of the smooth continuity of awareness, but from a scientific perspective, it certainly isn't.. One humble opinion..
@@ronhudson3730 Edited my comment for grammar..
Easy to understand that past and future do not exist but
a little trickier to grasp that neither is there a now.
What exists are things moving and our thoughts about them and
our thoughts consist of the complex patterned movements of a host of things.
This is truly fascinating, and I'm doing my best to grasp the concepts being discussed. Garrett's demonstration to illustrate spin and particle orientation is incredibly intuitive. The idea of attaching a clock to the particle to help explain time's role in this context is a clever realization. As particles move through the spacetime manifold, they also move in time depending on their speed, which is a concept that's challenging to put into words but seems essential to understanding the intricacies of quantum behavior.
I'm particularly intrigued by the relationship between spin and quantum field theory. The Dirac belt trick and the notion of holding an object to convey spin and degrees of freedom for different particles are captivating. It appears that these particles are intrinsically connected to spacetime itself, and their movements are subject to unique restrictions, which is reflected in their spins. For instance, photons with a spin of 1 can be likened to rotating a card 360 degrees to return to its original orientation, while electrons with a spin of 1/2 are connected by tendrils or fibers, which limits their movement.
It's intriguing to consider that the universe seems to maintain conservation laws even in rotational symmetries, leading to the observed spin behaviors. Exploring these concepts, particularly through the lens of degrees of freedom for rotation, can provide a more intuitive understanding of quantum behavior.
I share your enthusiasm for the potential implications of these insights, and I hope that we're moving in the right direction toward a theory of everything. Achieving such a theory could indeed open up numerous opportunities in science and technology, advancing our understanding of the universe in profound ways.

Relative to itself. No universal "backdrop". The only thing static and universal would be geometry itself. At rest would mean, either no transformations, or that the transformations are aligned. Because you wouldn't be able to tell the difference.
Time only has meaning when there is motion.
Motion relative to what though?

@@strings41you cant and thats because measurement itself presupposes change
@@strings41 I don't disagree with you but the point I was making was that that time (or motion) is only relative to a point of view, or having a position from which things can be measured. If you don't have a viewpoint (as in a consciousness) from which something can be measured then what happens to measurement?
@@haxstir Good point. Of course this topic is an exercise in abstract thinking, which is good for mental depth.
Having another candidate for the flow of time apart from entropy is something that excites me. The theory seems far from being completely baked yet though. But things like these give hope. I wish Lisi and his collaborators all the best for the future!
He's correct. ✅️
So you agree with his imagination? Silly humans! Read more non-fiction.
How long did it take for time to emerge?
Time is the fabric of the universe. Time is the energy that gives things the ability to emerge and exist. Everything emerges from Time. When you asked the question how long you were asking about an aspect of time. Duration. Length of time! The redundancy of your question answers itself. Time is the answer for everything.
Did anyone get it?
I don't have the background to conceptualize this theory but the mystery of time is of great interest to me and I like listening to the the theories about it. I agree with scientists who suggest it's probably not fundamental. Illusive as it is, I do think its true nature will be uncovered someday.
Fundamental? Someday? You really don’t understand time do you? Let us help you. Time is fundamental. We do not experience anything fundamental without time. Time is the fabric of the universe. Everything forms through time. Time equals energy. For example, you said someday. We do not experience day without our star the sun. When you said day you were calculating time by the motion of the Earth orbiting our star, the sun. No star no day. When we see our star, the sun, we are seen time in action. We experience time through our star the sun. We experience time every day! This video is pseudoscience. Read more nonfiction. Dictionary. Encyclopedia. Thesaurus.

Because an observer in a different frame sees a moving object get shorter doesn't mean the object actually got shorter. An observer moving with the object can measure that the object did not get shorter despite what the the person in the other frame sees.
You can also conclude you're not moving even though you are, depending of your choice of reference frame.

Now re-measure the speed of light, with regards to your also expanded yardstick, and with much longer wavelength light, which, from your perspective will have blue shifted to appear as the same wavelength used initially, as in your frame of reference time will have dilated such that the same lightspeed value is measured.

I have hard time relying on a person saying "right" after every statement.
What does he mean by his theory explaining which time frame is "at rest"?
That guy has no clue what he was talking about.
First all there is no way one can explain time before describing the notion of real and imaginary time as Hawking did.
I had to punt when he did not specify "at rest with respect to what?" There is no absolute standard of rest. So I guess he's saying that different rotations are happening in different moving reference systems, which makes no sense to me. Note that the "rotation" of the time axis in one system relative to that of a differently moving system is considered a "pseudo-rotation", and even that is a very specific rotation that has nothing to do with particles interacting. And yet he does seem to have some credentials.
An explanation of the Video with background: Unraveling Time: Garrett Lisi’s E8 Theory of Everything
Time is an ever-present facet of our daily lives, yet its true nature remains one of the most profound mysteries in physics. While we intuitively grasp the passage of seconds, minutes, and hours, physicists delve deeper, seeking to understand time’s fundamental role in the universe’s intricate tapestry. Among the theorists tackling this enigma is Garrett Lisi, whose ambitious E8 Theory of Everything proposes a novel way to explain time alongside the other fundamental forces and particles that constitute reality.
# The Quest for a Unified Theory
The Standard Model of particle physics elegantly describes three of the four fundamental forces-electromagnetism, the weak nuclear force, and the strong nuclear force-and classifies all known elementary particles. However, it leaves gravity out of the equation, prompting the ongoing search for a unifying framework that seamlessly integrates gravity with the other forces. Enter Garrett Lisi and his E8 Theory, which ambitiously aims to achieve this unification using the mathematical structure of the E8 Lie group.
# Symmetry Breaking: The Birth of Time
At the heart of Lisi’s theory lies the concept of symmetry breaking, a fundamental process where symmetrical properties of a system are disrupted, leading to distinct characteristics. In the Standard Model, symmetry breaking explains how particles acquire mass through interactions with the Higgs field. Lisi extends this idea, suggesting that time itself emerges from symmetry breaking within the E8 framework.
In Lisi’s model, the universe is envisioned as a four-dimensional fabric with the E8 group-a highly symmetrical, 248-dimensional geometric structure-superimposed upon it. This Lie group, comprising 248 circles, each represents a different elementary particle, such as electrons or quarks. The intricate twisting and interaction of these circles across the fabric give rise to the diverse particles observed in nature.
# The Geometry of E8 and Particle Interactions
To visualize this, imagine the E8 group as a complex, multi-dimensional lattice where each circle symbolizes a particle. The way these circles twist and interact determines the properties and behaviors of the particles they represent. When multiple particles converge at a point, the geometry becomes increasingly complex, reflecting the interactions that occur in particle physics.
Lie groups-mathematical structures that describe continuous symmetries, such as rotations-are central to this framework. In three-dimensional space, for instance, an object can be rotated in three perpendicular planes, corresponding to the three spatial dimensions. Lisi draws an analogy between these geometric rotations and particle interactions: just as sequential rotations can produce new orientations, particles interact and transform according to the symmetries dictated by the E8 group.
# Time Emerges from Twisting Geometry
So, how does time arise from this intricate geometric dance? Lisi explains that curvature within the E8 geometry plays a pivotal role. Curvature, in this context, refers to how the geometry bends or twists within space-time. If the geometry remains static, the curvature is zero, implying no change-akin to time standing still.
However, when the E8 group twists consistently in a specific direction across the entire space-time fabric, the curvature remains zero, but the geometry possesses a non-zero connection. This uniform twisting results in symmetry breaking, where the original symmetrical properties of the E8 group are disrupted. The direction of this twist effectively defines the flow of time, distinguishing it from the spatial dimensions and linking it to the behavior of fundamental forces.
This process not only differentiates time from space but also intertwines it with the Higgs field, which imparts mass to particles. By doing so, Lisi's theory elegantly connects the emergence of time with the properties of particles and forces, suggesting that they all stem from the same underlying geometric structure.
# Connecting to Special Relativity and Cosmology
Lisi’s theory doesn’t stop at explaining time’s emergence; it also integrates principles from special relativity. According to special relativity, as objects move, they experience time dilation, where a moving clock ticks slower compared to a stationary one. Lisi incorporates this by using a larger Lie group, Spin(3,1), which accounts for three spatial dimensions and one temporal dimension. The twisting of this group over space-time defines how time flows, allowing the theory to predict which frames of reference are at rest.
Moreover, Lisi’s E8 theory aligns with cosmological observations. It naturally leads to a space-time model known as de Sitter space, which incorporates a positive cosmological constant corresponding to dark energy-the mysterious force driving the universe’s accelerated expansion. By linking dark energy to the Higgs field within the E8 framework, Lisi offers a unified explanation that bridges particle physics and cosmology.
# The Road Ahead: Challenges and Implications
While Lisi expresses strong confidence in certain aspects of his E8 theory-particularly its geometric explanation of time and its compatibility with de Sitter space-he acknowledges that other components of the theory require further validation. The integration of gravity with the Standard Model remains a formidable challenge, and the scientific community continues to scrutinize and test the predictions of the E8 framework.
Garrett Lisi’s E8 Theory of Everything represents a bold and innovative approach to unifying the fundamental forces and particles of the universe. By proposing that time emerges from the twisting geometry of a high-dimensional Lie group, Lisi offers a fresh perspective on one of physics’ most enduring mysteries. Whether his theory withstands the rigors of experimental validation remains to be seen, but its elegant synthesis of geometry, symmetry breaking, and cosmological observations makes it a fascinating subject of study in the quest to understand the true nature of reality.

Garrett's E8 theory should not be ignored.. That being said, to ME, it almost sounds hallucinogenic.. It seems impossible to imagine a mathmatical "object" like the E8 lie group physically existing and able to create everything by changing/moving/twisting without the prior existence of time enabling such actions.. VERY possibly, I'm just ignorant here. Maybe someone can clarify..

@xtratub I can't see that perspective at all, friend.. The universe appears to be a very real PHYSICAL construct.. To say it is merely an illusion, well, that just flies in the face of our BEST current theories.. It sounds like an extraordinary claim with NO evidence at all to support it.. No?

Lisi says he is extremely confident about his result regarding the time aspect of his theory. Unfortunately for him, I can assure you that what he's saying is nothing more than a mathematical exercise without any relation to reality. For instance, he talks of De Sitter space, spacetime, and length contraction. However, none of these things exist in reality. It is nothing more than fancy mathematics, without any relation to real physics. So this all doesn't give any insight into the concept of time 😞

A time tracking device, a clock, is not time. Such a tracker is subject to internal and external physical influences such as speed, the force of gravity and the lack thereof, quantum field and so forth. When the time tracker is impacted so as to lose its internal calibration, it simply malfunctions resulting into a speeding up or slowing down in its time tracking system. Using a physical device as time itself is misleading and incorrect.

Consciousness is Symmetry breaking
Imagine a pencil lying down on a table. This is very symmetrical state for the pencil. But then consciousness breaks the symmetry of a pencil and start drawing.

oh, wow, cool. Dimensions are perpendicular, making rotations in the highest dimension orthogonal to the lower dimensions in a reference frame not rotating in the time direction compared to the observer frame.

@@0-by-1_Publishing_LLC That's all theories until proven by experiment, but the difference is there is some mathematics involved.
Time is broken up activities being brought together or separating through measurements of time.
I didnt understand a single sentence.
You were not supposed to. That shows you have common sense. What he was saying is unintelligible. The theory of everything it’s time. Time is the energy that connects relativity, gravity, and the quantum. The most obvious example that the pseudo scientist don’t mention is our star the sun. Our star, the sun is the reason for the elements on the periodic table. For example, we are our star. We experience time through our star the sun. The sun, our star is what time looks like in action. Time is the fabric of the universe. When we witness the universe, we are witnessing time. Time is how we experience existence. No time no existence. Pseudoscientists, misconstrue, science and provide misleading information, pseudo scientist provide manipulated data. Time is everything and everything is time. Time produces energy. The universe form through time. There is no beginning without time. The atom is not filled with mostly empty space. The atom is filled with time.
Time is not a clock. The matter that is used to make a clock formed through time! Clocks are human instruments used to and accurately measure time. Time is infinite. Time is the fabric of the universe. Space is human imagination based on science fiction. This video is pseudoscience. Fiction. He was not sharing a theory. He was sharing his imagination not even a hypothesis. Embarrassing!

Guy It inst correct. Fundamental Law of phich show undertimate particles are in and out at same and not time. Phich quanta time isnt existe in Particles field . Guys please check in Weiner Heisenbeger and Schordiger cat books.
I've encountered this before and it's quite appealing but I still don't get it. If someone were to ask me, I couldn't explain it to them at all. From what I've experienced, once you hit 'lie groups' it seems to go off into the woods. I haven't seen an explanation that works for me yet.
The theory of everything already exists... with enough material evidence.
I imagine even if the theory was correct, it would have to involve some concepts that are at the limit of human cognition. You are an ant trying to model reality itself. I don't think we could fully grasp if even if we someday bump into it.
The theory of everything is time. Time is everything and everything is time. Time equals energy and energy equals mass times the speed of light squared, no space. Space is human imagination based on science fiction. We experience time through our star the sun. No time no star. No star no planet. No planet no atmosphere. no atmosphere no oxygen. No oxygen, no consciousness. Don’t test nature by holding your breath. Breathe! While breathing read more non-fiction. For example, the dictionary the encyclopedia and the thesaurus. Silly humans! Must be white people. Lack of melanin.
@@andreicristian9575 we are humans! Speak for yourself. Humans understand how time works. We experience time through our star the sun. Time is the fabric of the universe. There is no existence without Time. Read more non-fiction. Science rebukes analogies. Science rebukes imagination. time is everything and everything is time. What school did you go to? They did you wrong. You were lied to as a child. We can help you. Read more non-fiction. Simple. Dictionary. Encyclopedia. Thesaurus. Strengthen your dialect. Perfect your semantics. Study linguistics.
I'm sorry, but this is not even close.

That doesn't explain why it is increasing and not decreasing.

Trying to follow this geometric explainer for ostensibly all of physics as we know it is breaking my mind. I find Garrett's conviction compelling, but the complexity of this theory violates my sense that the universe just can't be that geometrically complicated and interactive. I note with some disappointment that Garrett was not asked a very simple but CRITICAL question. Does this theory make predictions that are testable??? An unusual failure in an otherwise rock-solid series.
Ok.
No idea
This is called "over-engineering" - it's rampant in software dev too. I typically prefer a solution that *simplifies* in a straightforward, easily understandable way. Lie groups... circles... he involves far too many abstractions to explain basic ideas like an object rotating. I could rotate 2 of the rows of a Rubik's cube one way, and the other row the opposite way, but that doesn't mean "time is moving forward and backward" lol, there's nothing about that that's the case. That's the problem with casting all this into 3D geometry.
There is no objective "arrow of time", space and time are relative to an observer. Even the order of events is different for different observers (example: 2 stars burn out simultaneously, being nearer to 1 or the other makes 1 star burn out before the other because light travels at a constant rate). No 1 vantage point is "correct" or more true than the others. The very concept of order of events is not absolute, it depends on where you are, how fast you're going, etc. Same is true of space, mass, size... how much mass something has directly relates to its speed etc.
Special Relativity is essentially an explanation of how speed affects mass, time and space - that's already amazing.
I read somewhere that humans at some point in their life can only abstract in terms of their already existing knowledge, and lack the ability to realize it, while vehemently denying it. I'd say it's plausible that if we are to explain everything in the Universe to the smallest degree, we would be able to catch a glimpse of it through mathematics, to intuit it in a way, but not fully grasp it, otherwise we'd have to be all-knowing beings. If the math works for his model, which I'm not sure it does, visualizing it is a matter of subjectivity.
@@andreicristian9575 Well said. We can't jump to a totally unknown concept, we have to bridge the known with the unknown using analogies. Except maybe in dreams or psychedelia where you can experience a foreign/unknown but it's always so fleeting and you immediately forget, without concepts to cling to. It slips through. Given the nature of the universe, I don't think its entirety can be fully grasped in a single concept - you have to give up some truths to realize others. So anything we say the universe "is", is also "not" from many other perspectives. We can only speak of it in non-precise terms - to have precise terms is to take 1 vantage point or other, some relative frame of reference.
I wonder why this was re-posted after it was disproven in 2010. Distler, J., Garibaldi, S. There is No “Theory of Everything” Inside E8 . Commun. Math. Phys. 298, 419-436 (2010). Still an interesting idea I guess :)
He’s come up with A Theory of Everything but he’s still bald. That’s the first thing I would fix if I had it all figured out.
No way, since Nic Cage has gone bald it is awesome! Rock that look!
*"He’s come up with A Theory of Everything but he’s still bald."*
... Now, see? That's already covered in "Multiverse Theory!" In another universe there's a version of him that's a hippie.
Agreed, bald people should definitely not come up with theories until they fix their baldness. Then maybe we'll listen to them.
Animation when lol
Sounds coherent but how congruent is it with measured results - after the fact measurement?
Theory is wonderful if its coherency matches Nature with fine-tuned congruency. Don't be fooled, however, if coherency and congruency match really well. Ptolemy had a model of the revolution of bodies "around the Earth". His complex theory of cycles and epicycles and "efferents" was accepted till Copernicus and Kepler thought of something "simpler".
Don't get me wrong, complexity isn't automatically disqualifying. The assumptions behind the theory: the rules, however, matter.
Coherency and congruency do not mean reality. After all no theory of biological digestion can ever "explain" the urge called hunger. There is something more to reality, I think, than coherency and congruency can "dream of".
In other words, just as no thought can fill your belly, so no thought can stop time. A donut 🍩 may postpone hunger, just as a clock ⏰️ may be behind time. If you solved time would you also be able to solve eating? According to DC's Flash you wouldn't.
BRUH

That is the most stupid so-called scientific discussion I’ve ever heard.
Stop misleading ordinary individuals... there is no way one can explain time without first explaining the difference between the notion of imaginary and real time.
9:16 - and that's how we found God.
Cool theory - now prove it please...
Not being a mathematician, I don't fully understand Lisi's connection of Lie groups with time. Lisi seems confident about his ToE, but his overreliance on complexity and abstraction leaves me skeptical. Although my ToE also includes mathematics, it doesn't require a +160 IQ to understand how it works, nor should any all-encompassing explanation surrounding "Existence" do so.
The biggest problem with most ToE's is trying to explain the *"Everything"* part solely by way mathematics when that's just one piece of a much larger puzzle. Another problem is trying to attach "time" to something other than what it is (like space, dimensions, and now "Lie groups").
... Time is simply a "unit of measure" and nothing more, ... and what it measures is "change."
Yes, but there is something more to it. Change seems to have a preference when it comes to direction (towards chaos), for the entire Universe, not just me and you. Change also slows down when you observe it moving very fast.
Too smart for their own good. Time is, time moves forward, the end.

Jeez did not get a one word he said 😂some words. The elementary thing s geometry space has time beyond that if I m right rest places they have a time to. Can’t equation time distance is time that all believe very complex talk sorry
