A new paper,
"An Exceptionally Simple Theory of Everything", has attracted a great deal of interest, from both the scientific community and the general public. This forum comment thread will collect my short descriptions of this new theory, in response to questions posed from reporters serving different readerships. It's in chronological order -- sorry for the chaos.
Please don't add comments here (they won't be replied to) -- if you wish to discuss the theory, an appropriate thread is
the FQXi forum post where I first speculated on E8 Theory. If you'd like to read more about me personally, or leave an opinion or encouragement, there is an
Exceptionally simple personal FAQ.

--Can you sum up your current work in a way that a layman could understand? I understand that you're applying differential geometry to the problem of uniting general relativity and quantum field theory, but at the risk of sounding too simplistic, how does that work? And exactly what is differential geometry, anyway?
Differential geometry is the study of smooth manifolds, usually in many dimensions -- it's calculus on steroids. There are ways of classifying symmetric manifolds, and this links up with all other branches of mathematics; so differential geometry is sort of a hub where a lot of mathematics comes together. Now, there is one manifold in particular -- the largest simple exceptional Lie group manifold, E8 -- that is the most beautiful. The system of roots in the picture I sent you describes the 248 symmetries of E8. What I'm working on is identifying each of the elementary particle fields of the standard model and gravity as one of these symmetries. It turns out that this match is... perfect, as far as I've been able to tell. This model is very new, and there are still things I don't understand about it, but it looks perfect so far. You have to be very careful with these things though, as they can encounter a fatal difficulty at any turn -- and when theory contradicts experiment, or requires unreasonable revision, you have to toss it and move on. But this theory of fitting all the standard model and gravitational fields into E8 is working very well so far.
When we have a nice symmetric manifold, like E8, we can mathematically describe how this shape twists and turns over the four dimensional spacetime we live in. This description is called a principal bundle, and the field describing the twists and turns is called a connection, which determines the curvature. What I'm doing is identifying all the standard model and gravitational fields (everything) as parts of an E8 principal bundle connection, and it's working amazingly well -- it appears to have all the correct fields and their interactions. Each symmetry of E8 is a different part of this connection, and each symmetry manifests itself as a different type of elementary particle that we have in our universe. When someone unifies gravity with the other fields like this, it's called a Theory of Everything -- that's what I'm after.
--In the notes for your Perimeter talk, you call this an Exceptionally Simple Theory of Everything, but it looks pretty complicated to me. Is this the kind of theory that you're going to have to know a lot of advanced math and physics theory to understand, or is it something that can eventually be explained in a way that the average person might be able to comprehend?
Heh, I said it was exceptionally simple, I never said it wasn't complicated. Someone is going to need quite a bit of advanced math and physics in order to fully appreciate it, but I think even the average person has a shot at understanding the basics. The symmetric structure of E8 is described by how these points are arranged around the center of the picture I gave you. We can find the interaction between any pair of elementary particles by adding their two corresponding points (as vectors) to get a third. The rest of the theory consists of equations describing the dynamics of these particles. Even if someone can't fully understand the physics and math, there are many beautiful patterns in this E8 root system, and I find it very satisfying that something this mathematically and aesthetically beautiful could be at the foundation of our universe.

--Can you talk a little bit about the background of relating symmetries in mathematical structures to physical theories? Can you give our readers an example of when this has been done in the past, and how successful it has been?
Well, there are two different kinds of mathematical symmetry that have been extremely useful for physics.
The first is structural symmetry of the physical laws themselves. The shining example of this was in Maxwell's work on electromagnetism. Basically, Maxwell was playing with the equations as they were known at the time and noticed they were not structurally symmetric -- there seemed to be a term missing. When he added this term, the equations came together in a much more elegant whole. With this new, unified theory, he was able to describe the propagation of light as an electromagnetic wave -- when previously light had been considered an independent phenomenon. It was a very dramatic theoretical achievement. The biggest advances in physics have often come from unifications: Euler, Lagrange, and Hamilton's reformulation of mechanics; Einstein's special relativity; Feynman's path integrals; etc. The guiding principal is that the equations themselves -- the mathematics describing the universe -- should be symmetric and beautiful.
The second type of mathematical symmetry is more specific and familiar: the symmetry of patterns and shapes. In mathematics this goes by the name of group theory -- and the success of twentieth century high energy physics can largely be attributed to this kind of symmetry. A notable application was the construction of the quark model in the sixties, by Murray Gell-Mann and others. At the time, there was a large zoo of independent particles and no one knew why they had the properties they did. He managed to explain these properties in terms of symmetric patterns -- later understood as the group theory of SU(3). Currently, our best model of how the universe works at small scales, the standard model of particle physics, is based on group symmetries.

--Question 1: What exactly is a gauge group?
A gauge group is a high dimensional surface with many symmetries. Basically, it's a pretty shape. The complete set of these shapes was discovered and organized by mathematicians at the beginning of the twentieth century, and they're the centerpiece of modern mathematics and theoretical physics. Among the groups there are five "exceptional" groups that have special structures distinguishing them from the others -- of these, E8 is the largest, and the most beautiful, with 248 fundamental symmetries. The symmetries of a gauge group can be described by a pattern of points in eight dimensions, one for each symmetry.
Essentially, what I've done is associate each E8 symmetry with an elementary particle field of physics, including the entire zoo of standard model particles and gravity. Other physicists have previously matched the standard model particles to gauge groups, including E8 -- these are called Grand Unified Theories -- but I'm including gravity as well, which is something new, and technically this makes it a Theory of Everything.
--Question 2: What is a "principal bundle"? If the explanation is very technical, perhaps you could explain in which field principal bundles appear? What are they usually used to describe? How do they help you understand the symmetries that you are looking at?
A principal bundle is a playground for group symmetries.
If you have a group, it just sits there, looking pretty -- but when you let a group dance over another space, like the one we live in, you get all sorts of fields with interactions and dynamics. Mathematicians call this a principal bundle. These are the main object of study of differential geometry -- which is where calculus ends up if you stay in college for ten years. The basic idea is to allow a gauge group, such as E8, to twist around the spacetime we live in -- the twists are described by the "connection field." This way, each group symmetry looks to us like an elementary particle field -- parts of the connection. The dynamics of the fields, and their interactions, corresponds to the curvature of the twists.
--Question 3: You talked (in a separate message) about the symmetries of the particles in the standard model. How do you relate particle symmetries with symmetries in general relativity? That is, what features of general relativity have symmetry and then how do you compare those features with the particles of the standard model, in order to unify them? It seems like trying to compare apples and oranges.
You're right, it's strange. I didn't think it was possible to describe gravity purely as gauge symmetries until I saw Lee Smolin, Laurent Friedel, and Artem Starodubtsev do it in a 2004 paper. They referred to a somewhat obscure discovery made by MacDowell and Mansouri in 1977. They revealed that gravity can in fact be described using a particular Lie group. This was the seed idea that led me to combine gravity with the other fields, and led to the unification of... well, everything, using the E8 gauge group.
I'm not sure why someone didn't come up with this idea long before I did -- my guess is the physics community was distracted by string theory. Also, there's a theorem by Coleman and Madula that discourages this sort of unification. But the MacDowell-Mansouri trick gets around the Coleman-Madula theorem by using a different Lie group for spacetime.
--Question 4: What do you mean by a "really weird pattern"? How do you analyse the pattern? If it something purely mathematical, how do you interpret it and what features stand out as weird?
I had described the fields as elements of a big matrix, and this matrix was... lopsided. I had never seen a matrix that looked like that related to a group -- it looked weird.
--Question 5: Once you began to see this connection, how did you test it? What convinced you that it was correct? Did the theory predict features that we see in general relativity and the standard model (e.g. masses of the standard model particles, strength of forces)?
It didn't dawn on me slowly -- the realization struck all at once, and my brain buzzed with the implications. So it wasn't a "hmm, maybe this will work" kind of thing, more of a "holy crap, that's it!"
The interactions between the two hundred or so fundamental particle fields we know of are all known. This exact structure is there in the E8 root system. As far as I've been able to tell it's a perfect match of tens of thousands of interactions, all corresponding to the most beautiful mathematical structure there is. How cool is that!
There are still features of this correspondence that I don't completely understand. I'm learning more about it every day. And, you know, as good as these things start out looking, they can always turn out to just not be true about nature. So, this theory I've cooked up may be wrong. But it's looking very good so far. I haven't gotten to the point with the theory yet where I can confidently predict new relationships between the physical constants such as mass, but that's where it's heading. This theory is only a few months old. What I'm going to do is write up what I've found so far and publish a paper, so others can see the details and play with it.
--Question 6: Is there a way that we can test your theory? Are there predictions that it makes that will help it stand out from rival theories? Does your theory do away with the need for supersymmetric particles, or predict other particles that we could perhaps look for at the LHC?
That's correct, there are no superparticles in this theory. I made a bet with a pair of string theorists that superpartners won't be seen at the LHC -- we'll get to see how that goes. I think I'll be able to use this theory to predict a handful of new particles that might be seen at the LHC, but I'm not yet far enough along to say more. It's very exciting. I have a fun year of work ahead of me.
--Question 7: You mentioned that you weren't interested in working on string theory? What advantages does your approach have over rival theories, such as string theory, both in terms of what it can explain, and also aesthetic appeal?
There are lots of good things about string theory. It appears to be quantizeable, and can accommodate gravity in a fairly natural way. It also has restrictions that come out, due to anomaly cancelation, that say what can and cannot be a "good" quantum string theory. Originally people thought this would be enough, when coupled with the right background manifolds, to get all the standard model particle fields to correspond to oscillations of a string. But it's never worked quite right. In order to get it to work at all, string theorists have to bend over backwards and put in all sorts of things by hand. This is the main warning sign that a theory doesn't correspond to nature. What happens is, a theory looks promising, so people invest time in developing it. If it looks like it's matching nature, that's great. But if it doesn't quite fit nature, people have already invested a lot of time in the theory, so instead of abandoning it, they try to revise it -- they add stuff and try to patch it up. But the more you have to add by hand, without any experimental guidance, the worse the theory looks and the less likely it is to be true about how nature works.
I suspected at the end of the 90's that string theory had left nature behind, and was going off in its own direction without any connection with reality. And it wasn't spreading out in a proper search either, it was barreling along in one direction like a freight train, guided by a handful of theorists with many followers who were devoting their lives to the theory. I've never been much of a follower, so I walked off to search on my own.
For the record, I do think it's good that very talented people, like Brian Greene, are working on string theory. Everyone should be able to work on what they want, and strings may yet turn out to be the true theory of nature. I just have other ideas.
(If you write about my dislike of string theory, please include that I do think it's worthwhile for some people to work on it.)
This theory I'm working on has the main advantage of being testable -- it will very clearly be right or spectacularly wrong about nature. If it's wrong, I'll try to figure out if it's fixable, or I'll abandon it and move on. Another advantage with this theory is its relative simplicity -- there is just one geometric field, the connection over spacetime, and the interactions and dynamics come from its curvature. And, at the heart of this theory is the most beautiful geometric structure in mathematics -- it's very pretty.
--Question 8: What next? If you have unified general relativity and the standard model, does that mean that all the four fundamental forces are now accounted for? What is left for you to do? What do you think you will need to do or demonstrate to gain support for your theory?
Yes, all fields are present and accounted for. Nevertheless, there is a ton of work to do. First, I need to confirm that the particle assignments and interactions are all in agreement with known physics. Any deviations could be fatal. Second, I need to see what new predictions come out: existing particle masses, coupling strengths, new particles, etc. Third, the proper quantum description needs to be worked out. Right now the theory matches up well with methods of loop quantum gravity, which is why I've been hanging out so much with the LQG community. To tell you the truth, it's much too much for one person to work on -- but if it keeps going as well as it has been, it won't be just me working on it.
The talks I've been giving have generated a lot of interest -- one week ago I delivered a one hour talk to a packed seminar room at the Perimeter Institute. That went VERY well. I'm going to have a paper out on the arXiv soon, with full details, so people will be able to consider it and play with it for themselves.
I feel funny calling it "my" theory, since I've learned so much from the work of others. And if it works as well as it looks, other physicists will play with these ideas and develop the theory far more than I could. It's a little early to say, but what I think, at this point, is that this is nature's theory.

I should have a first draft of the paper ready tomorrow. If you'd like to look at it and you can keep it under your hat until Nov 7 or so, I'd be happy to send you a copy.
--Question 2: Are these 248 symmetries just symmetries in rotation, and mirror symmetries? Are there other symmetries?
There are other symmetries. They are not easy to describe, but together they make up E8. The pretty picture of the E8 root system describes how the 248 symmetries are related.
It is possible though to describe the symmetries of E8 in terms of the rotational symmetries of the root system polytope in eight dimensions. If you do this... there are 696,729,600 rotational symmetries! It's a very beautiful and complicated shape.
--Question 3: Are there 248 of these particles + forces? Or do you run out of particles and forces to associate with the symmetries and have to postulate the existence of extra particles or forces?
That's right, after the standard model and gravitational fields are fit to the 248 there are a handful of extra particles and forces -- new particles. I currently only have some clues as to what these are, so I can't make definite predictions about them yet. It's still a year or so until the LHC turns on...
Question 4: For the cases where they matched the standard model but not gravity to E8, were there "spare" symmetries left over, that hadn't been associated with anything? And if so, why didn't anyone think to stick gravity in?
Two reasons. First, most people were distracted by working on string theory, which handles gravity differently. Second, the Coleman-Mandula theorem says you can't combine the Poincare group with other groups in a larger group that includes gravity. So people weren't looking for it, and if they were they didn't think it was possible. But there's an obscure way of describing gravity, compatible with Einstein's general relativity, called MacDowell-Mansouri gravity, invented in 1977. When I learned about this from people in the loop quantum gravity community, I saw how it could all fit together. Using this formulation, gravity can be fit together with the other symmetries, and it dodges the Coleman-Mandula theorem by not using the Poincare group. The Poincare group is the symmetry of a flat spacetime background -- the MacDowell-Mansouri formulation implies we should use a curved spacetime background instead, called deSitter spacetime. Conveniently enough, this also means there should be a positive cosmological constant, which is what we see.
--Question 5: At first, I thought that you were saying that you *begin* by identifying the particles and the forces with symmetries. But here it sounds more like the elementary particles and fields fall out only after you have set up E8 and started manipulating it? Which is correct?
Both.
We know there are a bunch of particles with charges, and we know how they move and interact. And the two are related. I've used these known charges to identify the particles as symmetries of E8, and using the curvature we can write down the action that describes how they move in a way thats compatible with what we know.
In order to know what charges particles have, you have to work backwards from how they move and interact.
-- Question 6: How do we see or recognise these fields in the maths? Don't they just manifest themselves as other symmetries? What I mean is, intuitively I could imagine associating particles with symmetries and then letting that group "dance over a space" and seeing gravity and other forces appear as interactions. But you have associated the forces _with_ symmetries too, so what sort of interactions and fields are now being created? What do they correspond with physically?
The interactions only happen through the exchange of particles. As you probably know, the electric force corresponds to the exchange of photons -- the field quanta of electromagnetism. A particle, physically, is what you have when you quantize the symmetry fields, mathematically. This can get very tricky, especially when you bring gravity into the picture. No one knows yet how to properly quantize gravity this way.
Each of these fields, corresponding to a group symmetry, dances over spacetime and interacts with the others -- producing all the known particles and forces between them.
--Question 9: What do you mean by the "root system"?
A "root" is what the points are called in the pretty pattern that describes the Lie algebra. They're also called eigenvalues. Or, if you're talking about this pattern in eight dimensions, these roots are the vertices of the E8 polytope.
A polytope is a fancy word for a polyhedron in a higher dimensional space.
Question 10: What sorts of things do these interactions correspond to? Specific strengths of forces between any two particles?
They correspond to which particles interact with which, to make other particles. For example, an electron can interact with an electroweak boson and become a neutrino, a quark can interact with a gluon and become another quark, etc. These interactions correspond to Feynman diagrams, which is what quantum field theorists use to predict things amazingly well.
--Don't worry, Garrett, I'm not interested in printing a story about an imaginary fight between you and the string theorists. It's just that most of our readers have heard of string theory, so they would be interested to know why this is better.
Heh. The fight isn't imaginary.
I'm just one guy, and I'm the first to admit this E8 theory is a longshot, but it looks pretty good. If it works it will be a beautiful unified theory that agrees with the standard model and gravity, as well as predicting a few new particles. And it's better because it works without strings, branes, extra spacetime dimensions, superparticles, Calabi-Yau manifolds, or other weird string theory inventions that there's no evidence for.
If I thought string theory was better, I'd work on that instead.
--Question 12: How do you model the curvature of spacetime using E8?
The Riemann curvature of spacetime is part of the curvature of the E8 connection.
Question 13: So this is an important point for me to clarify. I had thought that if your theory is correct it would do away with the need for people to work on either string theory or loop quantum gravity. But it sounds like maybe your work is showing that LQG is productive. So would the best way to think about it be to say that E8 provides the foundation for LQG?
Close. This E8 theory is a competitor to string theory, but string theorists could easily work on it since it's much simpler. It will be interesting to see how that develops -- see if anyone defects. I don't expect string theorists to work on it though, because I'm not in their club.
LQG... A better way to think about it is that LQG provides a foundation for E8 theory. The whole thing came together when I was trying to figure out how to combine the standard model with recent work in LQG. In LQG the field describing gravity is a connection. I was able to use a larger connection to include... everything. I was amazed that it worked! So what E8 theory will be, when it's quantized using the methods of LQG, is Loop Quantum Everything. Heh, that's going to be a good title for someone's paper in the future.

For a magazine image, you may want to use the image of G2 and use some arrows and text box overlays to describe how the interactions between particles correspond to visually adding together the points in these diagrams. This will be the best part of this theory for most people -- you can actually determine how all the particles interact by how these points add together in these pretty pictures.
For example, if you look at the picture of the G2 root system in the paper: Take the green up triangle (that's a green quark) and add the blue circle on the far right (a red-anti-green gluon) and you get the red up triangle (a red quark). This is how the quarks interact with the gluons. It's vector addition -- maybe you can overlay some arrows over the G2 picture to describe how this works for your readers.
When we do the same thing with the points in any of the E8 pictures, we get all the allowed interactions between the particles. :)

--If there was no universe -- to my na?Øve thinking -- we wouldn't have (or need) string theory or LQG. But the logic of E8, as a pure mathematical object would still exist and the mathematical properties it has would still be true without there having to be an actual universe in which E8 is realized. So, intuitively, it seems to me that E8 should be more fundamental than LQG (and string theory). Does that make sense? And if not, what is wrong in my reasoning?
That's not so na?Øve -- that's the Platonist world view, and is shared by many physicists and mathematicians. The E8 Lie group is a more central structure in mathematics than spin networks or strings. But spin nets and and strings are mathematical structures in this same way you're describing -- so you can't necessarily exclude them just for being more messy.
What I think is that the universe is pure geometry -- basically, a beautiful shape twisting around -- and this shape is described by mathematics. This is a slightly different view than believing the universe IS mathematics, but it's close. Since E8 is perhaps the most beautiful structure in mathematics, is very satisfying that nature appears to have chosen this geometry. And quantum mechanics seems necessary for everything to happen.
--2) Also, I was reading something Lee Smolin is quoted as saying about LQG. He mentioned that LQG may need to invoke a multiverse, just like string theory. Does E8 do away with the need for a multiverse? (At last, we can explain why everything is the way that it is -- and it's down to the shape of E8.)
I'm afraid E8 doesn't say anything directly about quantum mechanics, so it doesn't help that way. Although there are hints of how it might connect to quantum mechanics, algebraically.
The multiverse is what you get when you think about quantum mechanics operating on the scale of cosmology. Personally, I think "many worlds" and "multiverse" are just fanciful ways of saying there are many possibilities for what can happen.
--3) Does your analysis of E8 explain the relative strengths and ranges of the forces, and the relative masses of particles? (Sorry, if you have answered this one already.)
This is the goal. Right now it looks promising, but it's not there yet. All the pieces are in place to calculate these things, but some parts aren't perfectly clear, and it's going to take more work to find out one way or the other whether the correct coupling constants (force strengths) and masses come out. This is an "all or nothing" kind of theory -- it's either going to be exactly right, or spectacularly wrong. I think it has a good chance of making successful new predictions, which is why I work on it, but it could still turn out to be wrong. It aint over 'til the LHC sings.

-You probably answered this in another email that I buried, but I'm not sure whether to refer to E8 as an 8-dimensional object or a 248-dimenisonal object (or something else.)
The E8 Lie group is a 248 dimensional object. It is a very complicated, and very beautiful, smooth, curved manifold with many different symmetries. ("Manifold" is a fancy name for "surface.") This Lie group is the pretty shape at the heart of E8 theory.
The E8 root system, which is what's shown in the pictures, is a pattern of 240 points in 8 dimensions. This pattern of points describes the shape of the E8 Lie group, through its Lie algebra. The pattern in 8 dimensions is projected onto the 2 dimensional page from different angles to make the different pictures. By understanding this pattern, we get a better understanding of the E8 Lie group.
The elementary particles correspond to points in the E8 root system, which correspond to elements of the E8 Lie algebra, and thus to symmetries of the E8 Lie group.
I'm sorry this is so complicated, but I hope that's clear.
--Thinking in terms of a hypercube when we say, think of a cube in 3D and then you can think of another axis, orthogonal to the first three and that would give you 4D, etc...and in that way you can keep going and describe an n-dimensional cube. In THAT sense is E8 eight-dimensional (existing in the same space an 8D cube)? Or is it 248-dimensional, existing in the same space as a 248-dimensional cube.
The E8 root system is eight-dimensional in this sense. And it is a polytope, like the cube and 8D cube are polytopes.
The E8 Lie group is not a polytope, it is a smooth, 248 dimensional surface.

--I also wondered if the NS version is correct, see below.
It has some slight errors (physics has never been just a hobby for me -- it's my life), but for the most part it is accurate. I don't see any significant embarrassing errors or misstatements in the article.
--Does this mean we do not need any more than four dimensions, for example?
That's correct -- this E8 Theory only works in four dimensions.
--And how likely is it that the LHC could find one of those 20 new particles?
The theory is very young, and still in development. Right now, I'd assign a low (but not tiny) likelyhood to this prediction. For comparison, I think the chances are higher that LHC will see some of these particles than it is that the LHC will see superparticles, extra dimensions, or micro black holes as predicted by string theory. I hope to get more (and different) predictions, with more confidence, out of this E8 Theory over the next year, before the LHC comes online.
--If you could let me know today, that would be great.
Certainly. Things are developing very quickly with this new theory.
I posted the paper to the physics arxiv on Wednesday, Nov 7:
http://arxiv.org/abs/0711.0770
It received an unusual (perhaps unprecedented) amount of attention from physics bloggers (in chronological order):

(This is the best and most informative review of the paper.)

(This is string theorist who, not surprisingly, hates it. Fortunately, his only real arguments against it are vacuous.)
http://www.math.columbia.edu/~woit/wordpress/?p=617
(Another level headed review)
Those are the main reviews and discussions of the paper so far, though there are several others (Physics Forums, etc).
Two hours ago, I presented a one hour talk on the theory to the International Loop Quantum Gravity Seminar:
http://relativity.phys.lsu.edu/ilqgs/
That is a weekly teleconference with a consortium of researchers at fourteen universities around the world. I'm happy to say it went very well.
I'm a little overwhelmed by all the attention, as I'm a bit of a hermit. But I'm quite pleased the physics community is as excited as I am about this new E8 Theory.

--1. First of all, in laymans terms: What the heck are you talking about?! Seriously, is there any way to impart to the average Joe what a unifying theory is, and why it's important?
Most people may be familiar with some of the various kinds of elementary particles, like electrons, quarks (that make up protons and neutrons) and photons (particles of light). These particles have charges. The electron, for example, has an electric charge of negative one. But there are also several other forces we know of, besides the electromagnetic force corresponding to the exchange of photons. The four forces are electromagnetic, weak, strong, and gravity -- and each force has a set of particles attached to it, and a different kind of charge. Each elementary particle can be uniquely identified by the charges it has. And there are a lot of elementary particles! About 200 or so. What I found was that the charges of all of these particles are not just random numbers, but that they match a pattern. The pattern represents the most beautiful geometric object in mathematics, E8. This is the "largest exceptional Lie group" -- essentially, it's a very large, very beautiful shape. And this is why it's so exciting. If this E8 theory is correct, it means everything in the universe corresponds to how this beautiful shape twists and dances over our four dimensions of spacetime. It would be very satisfying if our universe corresponded to the most beautiful geometry known to mathematics.
--2. Your work is showing up among the most popular discussions on the web; what do you think about all the attention?
I enjoy a quiet, contemplative life, interspersed with playing outside. The media attention has been amusing, but stressful for me. I think it's wonderful if I've motivated people to think a bit more about how the universe works. And it's great that people are so interested in this theory I've put forward. It is a beautiful theory about nature, but it might be wrong -- that's how science works. It's not enough that it's beautiful, it needs to agree with experiments. Also, this theory is young, and still in development -- it may change significantly, or it might turn out to not work. If it doesn't work, I go back to the drawing board. But in any case, it's a good adventure, and there's nothing I'd rather spend my time doing.
--3. The criticism I've read seems to span the spectrum, from you're brilliant, the next Eistein, to... Well, you know. What do you think about the critiques?
Einstein's construction of the equations of general relativity was the most amazing and beautiful accomplishment in theoretical physics. And it provided true insight into nature, with testable predictions that have held up for a century. Even if this E8 Theory is successful, it won't equal what he did to revolutionize physics. Also, this E8 Theory did not come from my effort alone. The program to unify the laws of physics has a long history, and many people have built it up over decades. I just hope I've advanced physics a little further with my ideas. And I expect that others will use this paper I've written, and continue developing E8 Theory in ways I haven't imagined. Or, the theory may fail. One needs to maintain a healthy skepticism, especially for ideas without experimental support, however beautiful they are. Criticism of a new theory is healthy. The scientific process will work it out.
--4. From a physics stand point, which is better, surfing or snow boarding?
Ha! There's more going on while surfing, with water and wind rushing all around you -- it's about chaos and taking chances. Snowboarding lets you draw a cleaner line -- it's more geometric and deterministic. The difference between these two is a lot like the difference between particle physics, with it's many quantum particles careening off one another, and Einstein's theory of gravity, the smooth geometry of curved spacetime. I think, for completeness, you need both.

--You added the charges of each quantum particle and came up with the E8 group. Or did you plug the particles into the E8 and found that they corresponded correctly? (What I mean is, would it be closer to likening your process as plotting out different particles as a different symmetry, and overlaying them accurately coincides with E8; or did you calculate the charges of each particle and, on a graph, what emerges is E8?)
The two different descriptions you're giving are related (thus the confusion). The E8 Lie group is a large (248 dimensional) symmetric manifold. It has 248 symmetries, each corresponding to a Lie algebra element. The relationship between these symmetries can be described by a pattern of points in an abstract eight dimensional space, with each point corresponding to a symmetry of E8. This is where the pretty patterns come from. Each elementary particle corresponds to a symmetry of E8, and hence to one of these points in the pattern. And each of these has eight coordinates, corresponding to the eight quantum numbers (charges) for the particle.
The main thing I've done is to figure out all the quantum numbers of the particles in the standard model, and found that these match the points corresponding to E8.

Can the triality matrix (whcih 'rotates' the different fermion generations), be considered as an 'operator' working on the E8 'eigenstates'? If so, there will probably be some root vectors for which T does not 'commute'. Otherwise the fermion generations would be degenerate states with equal mass. Could the simple search for these roots (without second quantisation) result in the mass gaps for the generations and maybe even the kiode relation? Something like: m(e)=||^2=||=..=factor.||^2

Garrett, thanks for offering a venue for the closure to 20th century theoretical physics. Perhaps you shall have liberated some talented theorists who will pick themselves up and move on to new phenomena. A slightly larger "everything." In addition to various "mysteries" that the experimentalists have meekly assembled over the last 20 years while the theorists have been engaged in synthesis, I am hoping for insight into some traditional issues like the existence of conciousness. Is the 'substance' of mind a topic for physics or not? Does some principal bundle describe my sensations of taste? Is my sensation part of everything or not?
Here is another/same issue. Any application of manifolds assumes some degree of smoothness in overlap maps. Often there is an implicit degree of differentialbilty of any vector fields on the manifold. All the more so for principal bundles. What are the consequences of relaxing the differentiability requirements? How should this be done? I am thinking, in Newtonian mechanics, if all the force fields are assumed to be at least once differentiable then there are always unique solutions determined by initial conditions. On the other hand, if one assumes the the force fields are simply continuous, then there are always solutions for the motion of a particle, say, but the solutions may not be unique for any set of initial conditions. (theorem by Cauchy) I am wondering under what criteria the dynamics implied by a connection imply there will exist non-unique solutions.

Garrett,
I actually like your title "An Exceptionally Simple Theory of Everything" and this post is to suggest you that your work might might concern "absolutely everything".
I hate to talk about me - but I need to etll firts that I just completed the report of an experiential learning in socio-eceonomy - that ended with a geometrical method to handle problems in those fields with an unexpected - and seemingly universal - manner.
Our experiential developments did drive us at constructing maps, next within the difference group - to which belongs "mathematically speaking" the well known double-entry accounting system - and from there we constructed a spheroid manifold that may embed all or any reality.
Everything we did is not out of theory but out of experience - and it looks that you only proposed the global theory that may encapsulate - say explain - all of our operational methods.
Of course we only know an experimental side of our methods and still we have to check how much a generalization of your work would fit with them - but in case the answer would be positive, your proposition may lead applications in many other domains than only physics.
In any case, congratulations for your work and your proposition.

This question is surely out of subject, and probably naive, but let me ask this : if particles are travelling in the time dimension in the "opposite" direction, could they be detected ? Are there exemples of particles travelling to "the past". Is the causality principle a scientific concept, and why ?

You mention in the xrv article that symmetry breaking should have a mathematical explanation. Why is that, philosophically? To my mind, symmetry-breakings are where we find all the creativity in the Universe, from the matrix of symmetries (however beautiful they are!) -- call it Deontic if you will. It's where all the 'meaning' of interaction, 'chaos - aka complexity', and serendipity (eg. fluctuation-dissipation, or even just information transported on momenta transfer) comes out, informing us rather than we informing it. Kind of like those rogue breakers that really get your heart going.

Garrett,
I have been following the cosmology world for 40 years. For the last 20 I have used this as a thought problem for countless hours on many long drives. By the time Brian Greens book came out, I was comfortable through roughly the first half, and then it went out of control. As you say, working to hard to force a fit.
At times on those drives, I would almost sense a ghost of what was needed, but it was far to complex to imagine. But I did predict to all of my peers that the person who solved it would not one of those sought the answer from bashing particles together, but rather the solution would come from someone who rubbed thoughts together. You proved me right on that.
For what it's worth, although I could only imagine a ghost of the E8, the instant that I saw the shape in the Aim E8 website, I felt the same as you describe above, Holy crap, that could be it. I could never imagine it but when I see it is just what is needed. If it isn't it is is so damn close.
Credentials.....Just a guy whose friends say thinks too much.
Good job and good luck to you in solving the details. Thank you for opening the door closed for 100 years.

First, congratulations for developing a beautiful testable physical theory, for making it reasonably accessible at this early stage to interested non-mathematical laypersons such as myself and for expressing your balanced personal philosophy of life.
My question (and concern)is this. Does the development of your theory have the potential to lead to the development of weapons which will exploit this more unified understanding of the physical structure of the universe and be even more destructive than present weapons?

Garrett:"The Riemann curvature of spacetime is part of the curvature of the E8 connection"
It would of course be wondeful to see this in it's natural setting. Would the Riemann Hypothesis be such a place?
"On the occasion described by Mr. Derbyshire, Hugh Montgomery, a graduate student was chatting with the great physicist Freeman Dyson, when Montgomery happened to mention his findings on the distribution of prime numbers based on Riemann's Zeta function.
Dyson, one of the most highly-regarded scientists of his time, poignantly informed the young man that his findings into the distribution of prime numbers corresponded with the spacing and distribution of energy levels of a higher-ordered quantum state."
I asked Tommaso Dorigo such a question happening at the heart of the colliders. About gravity.
"It looks as though primes tend to concentrate in certain curves that swoop away to the northwest and southwest, like the curve marked by the blue arrow. (The numbers on that curve are of the form x(x+1) + 41, the famous prime-generating formula discovered by Euler in 1774.). See more info on Mersenne Prime."
Do you see any relation?

Garrett,
If I Have understood this correctly the whole idea can be understood by picturing the concept in the same way Mr Carl Sagan did in his televison series from the 80th. In this science program an idea was put forward to give understanding of more than 3 or 4 dimensions to reality as we can persive them. The consept eas explained by relating to a world that had only 2 dimensions - and this world was named Flatland. If a 3-dimensional body were to manifest itself in this 2-dimensional world it would be like if you cut an apple in two - and "stamped" it on this flat surface. To the inhabitants of Flatland a sudden shape would emerge from out of noware - and leave a mark - and then disapear - without a trace.
So if I have grasped the idea here - the quarks and other manifistations in our space time continium is mearly a manifistation in our 3 or possibly 4 dimension wourld from this 8 or 256 dimensional reality that this E8-theory predicts
My question now is - have I got the idea or not?
Regards and keep up the good work

if we "connected" different Gs do we get other (but presumably non-actual) self-consistent physics ? Or does M's structure constrain the choice of G?

berlin,
Something like this may happen, yes. If the three generations didn't have different E8 quantum numbers, there would be no way for them to be different in this theory, and no way for them to have different masses.
Daniel,
Damn, what the heck's the point of building a secret doomsday device if you're just going to blab about it?
If someone does use E8 to blow up the world, it will be long after we're already gone.
Plato,
Just because I don't see it doesn't mean it doesn't exist. Hmm, but that image does happen to look exactly like my right thumbprint... very odd.
Bo,
The E8 principal bundle over spacetime is a 252 dimensional space, called the "entire space." But, unlike in Kaluza-Klein theory, the 248 dimensional E8 Lie group is a "frozen" shape over spacetime points.
Lee,
I never described this theory as a principle bundle, it has no moral fiber.

Thanks.

The idea of E8 is awesome! We need a great unifying theory, and this seems to fit very well. It does suggest that the universe, etc, must have a designer, much in the same way that a clock's operation suggests the existence of a clock designer and maker. The study of objects seems to have mankind looking for an ultimate of some sort.

I can understand the idea of trillions of universes with randomly selected laws of nature, a few of which just happen to be conducive to life.
However it seems unlikely that the "life friendly" universes will have perfect and beautiful geometry, or that
such geometry should result in "life".

I'm a complete non-scientist, but in trying to understand your theory, I was reminded of Carl Jung, who believed that mankind often created symbols in an attempt to reconnect with the unconscious " archetypes" that he believed formed the essence of the universe.
Jung was convinced that these archetypes were psychoid, that is, "they shape matter (nature) as well as mind (psyche)" That archetypes are elemental forces which play a vital role in the creation of the world and of the human mind itself.
so when I saw your youtube video of E8-- it looks so much like so many primal man-made symbols that Jung would flip over-- suddenly your theory had a real power for me, even if I couldn't understand the details of the science. so for that -- thanks, dude. you're my official new hero.
I don't know if the theory is "factually" correct, but I'm sure it's instinctually correct
as a soul surfer my bet is you've had some of these same thoughts. care to comment?

What makes you believe the unrealizable trillions of universes with randomly selected laws have any reality outside your imagination? The existence of the universe is the greatest mystery, but arguments like this seem a cop-out shortcut to its solution. I prefer to live with the mystery. Why do you accept three space and one time dimension as mundane, but consider E8 exotic?

Andrew wrote on Dec. 15, 2007 @ 23:12 GMT
If E8 theory is correct then:
1) There is only one universe or type of reality,
2) That universe has a structure that is beautiful and symmetrical,
3) And because of that structure intelligent beings must evolve.
Either you believe in a Creator or that life came about through random selection. If you believe the latter then
there must have been a huge number of different types of random universes to be selected from in order to find one with something as improbable as life.
There seems to be no reason that the "lucky winner" would, by chance, have life, and also by chance, be based on a simple, orderly, and beautiful geometry. This would only happen if one required the other---and that idea has hints of religion about it.
As someone once said, "Maybe the universe is complicated, chaotic, and ugly."

From a recent interview:

I had kind of wondered about that, since the representation theory involved has a visually appealing aspect that would probably make for a good SciAm article. But I certainly appreciate and commend conservatism, especially since some of the media response went overboard.
--but I _am_ doing a short "second day" story (more like "second month" at this stage) briefly assessing where things stand now that the shouting has died down.
OK, great, I'll help out however I can.
--Mainly I just need to confirm that I have the right impression (from following various threads online, such as the PhysicsForums thread) about what you are doing with regard to the theory. Namely, you continue working on it to try to overcome the various problems that were pointed out (some of which you had already mentioned in your preprint as being areas needing further research).
Yes, that's correct. The largest problem is the description of the second and third generation fermions, and this was discussed extensively in the paper.
One thing I could have done a better job of, but will try to remedy as things develop, is describing the fact that this general technique of describing all fields of the standard model (bosons and fermions) using one connection does work to describe what we currently know. It is only the fit to E8 that is rather tenuous at this point -- but this fit to E8 was such an exciting possibility that I ran with it in this paper.
--Also, do you have any real collaborators at this point?
I prefer to work on my own, although I've certainly been communicating with a great number more people. It's been so long since I've worked with a collaborator, I'm not sure I remember how. But I have been talking with people as they've worked through the paper and used parts of it to pursue their own ideas, which has been good.
--Have you been invited to give talks anywhere recently?
Yes. My earliest upcoming talks will be at the TED conference on Feb 28, then I'll be talking with physicists at UC Davis on March 7.
--About the problems... I know from the beginning you've been saying that the issue of getting all three generations of fermions "needs further research."
Yep, right now there are just many interesting clues.
--About Distler's claims that even one copy of the proper chiral representation does not sit inside E8 as it needs to, I understand your position is: you're not sure if Distler is right in his claims
Yes, I think he may be making a mistake in his choice of complex structure when he uses conjugation to replace right-chiral fields with anti-left-chiral fields in describing the standard model. It's a subtle calculation, and it's possible that either of us could be confused on this point. I prefer to work through these things slowly and carefully before enjoining arguments though.
--even if he is, using the complex form of E8 instead of the real will, without any doubt, fix the problem.
Yes. If you read his argument, he's unhappy with the way the real spinors in E8 are being twisted in this theory to build complex spinors. If you start with complex spinors in complex E8, there's no problem -- at least not for the first generation. But at this point I'd prefer to stick with a real form of E8 if possible.
--I have to say the issue that bothers me the most is the fundamental one of mixing fermions and bosons so closely together without having some kind of superalgebra.
Ah. There is actually a large but unfortunately somewhat byzantine literature on this construction -- it's part of the BRST formulation.
But the mathematics of this construction are rock solid. The place I first learned about it was in this review paper:
http://arxiv.org/abs/hep-th/0201124
where, on page 70, it's defined and described as a "generalized connection":
w = A + C
in which A is a 1-form and C is a Grassmann valued field, both valued in parts of a Lie algebra.
Using the algebraic structure of the exceptional groups, the C can be a spinor field algebraically. Unlike in supersymmetry, these A and C never mix -- so they can have different units without difficulty. The main advantage of formally adding them is for the distributive property in the Lie bracket -- giving an expression referred to as "The Russian Formula." (Have a quick look at page 70 of the above reference).
For a more mathematical description of this kind of BRST extended connection, this recent math paper is typical:
http://arxiv.org/abs/0710.5698
Unfortunately, this sort of BRST symmetry is less familiar to people than supersymmetry, even though it plays an essential role in QFT.
You might have noticed that Peter Woit also likes the idea of possibly interpreting these "ghost" fields, C, as fermions.

While I don't understand the incredibly difficult math and other operations you have used to assemble this theory dude I think you may have gotten it.
I have been trying to get a feeling that string theory was the way to go for many years now. To no avail. Calebi Yau? Vibrating strings? While it was getting close, it IMO missed some things. Things that I could not get. Brian Greens book was the best book out there that I read.
Intuitively, it seems that you have something here.

Garrett,
Can BANG CRUNCH BANG be right if it is a balanced equation.
The energy equation for ex-nihilo does not balance it is 2E=2M*2C^2.
But the energy equation for the big crunch balances it is.
1/3 APPLE+ 1/3 ORANGE+ 1/3 ORANGE= 1 APPLE/ORANGE.
Iam amazed by the intolerance of this community.
The equation for the universe must balance for evolution since you cannot get energy from outside the universe from another dimension like in ex-nihilo.
The four states of matter become one.
1/3 FERMI DIRAC EQUATION+ 1/3 BOSE EINSTEIN+ 1/3 BOSE EINSTEIN= 1 BOSE EINSTEIN/FERMI DIRAC.
And one unstable state of matter explodes to become four.
Of course this can be a better bomb but it can also be a better nuclear reactor.
Particles X an Y cannot be in the SAME STATE at the SAME TIME in the SAME PLACE except before the big bang.
The previous universe may have been a Godel one and a contradiction in terms of time so that it gives rise to a non contradictory explosion and the laws to our universe.
What is so silly about that that you can't print it.

Hello Garrett,
I'm only a physics amateur, I write from Pesaro, Italy; I would ask you this question (or more probably to correct my question if badly formulated):
Which kinds of "charge" are beyond the 8 dimensions of the E8 root space illustrated in the famous beautiful animation ?
Perhaps I did't understand enough your phrase ("And each of these has eight coordinates, corresponding to the eight quantum numbers (charges) for the particle"), but I would expect somewhat like:
Axis 1: electric charge
Axis 2: strong interaction "colour"
...and so on.
Of course, I'm an enthusiastic fan of your E8 theory, I'm 45 and it is what I hoped to see when I was 20 and I read about electroweak unification... Please continue to keep us prophanes informed! Thank you and good work!

Dear Dr. Lisi
I am 85 years old and thought the following may encourage you to continue your excellent work. What the young W. Heisenberg had to do to get his Nobel prize and invent quantum mechanics was to make sense of thousands of numerical results found
experimentally. Without really knowing what he was doing, he told me he went on making patterns out of these numbers and invented rules to make them follow any system at all. Later on his Prof. Max Born discovered that his student Heisenberg had rediscovered an obscure part of mathematics called matrix multiplication which does not commute. You and your colleagues are not doing numerology when you are fitting the standard model into E8. You are doing basic and fundamental physics modeling. Those who say this is numerology do not understand either physics or mathematics, or in fact numerology which was an important part of the work of Backmeister Fuller.
With my best wishes to you, El Naschie, Lee Smolin and all free thinking and adventurous young men like you.

Hi Garrett,
Have you had an opportunity to read my book on “New Approaches Towards A Grand Unified Theory”?
Upon reading your theory again (and I still don’t understand everything!), I think I can better translate the bosonic component of your theory into my theory. As a Particle Physicist, I preferred to call my theory a GUT, because TOE is String Theory nomenclature, and I was slow to embrace the importance of multiple (10, 12, 26?) dimensions. In Sections 7.3 and 7.4 of my book, I came to the conclusions that the first ten dimensions are composed of spacetime and two hierarchal (in the sense that one is more physically relevant to our spacetime than the other) 3-branes; that these dimensions unite as a 10-dimensional SU(11) “Bosonic GUT”; and that the forces relate to dimensions as follows: Strong (1st and 2nd D), Electromagnetic (3rd D), Weak (4th D), Hyperflavor (5th and 6th D), Gravity (7th D), and WIMP-Gravity (8th through 10th D). In Section 7.5, it looks as if the three dimensions of WIMP-Gravity might collapse into one dimension that interacts with tardons, and two dimensions that interact with tachyons; which implies that my 10-D SU(11) “Boson GUT” may collapse into an effective 8-D SU(9) “Boson GUT” of order 8 x 10 that could coexist with fermions in your 8-D E8 TOE of order 8 x 31. I agree with the possibility of an effective 8-D GUT/TOE, but String Theorists will not be happy with such a small number of dimensions.
I thoroughly enjoyed your G2 approach to the Strong force. It is very similar to my U(1) x SU(2) x SU(3) approach to Hyperflavor-Electroweak. The difference is that your 2-D approach uses nested 2-simplices of quark and anti-quark colors, whereas my (2+1+1)-D approach uses nested 3-simplices of quark and lepton hyperflavor-weak isospins.
The biggest difference between our approaches is that I introduced a (2+1+1)-D Hyperflavor-Electroweak and a (3+1)-D Gravity/WIMP-Gravity (that might collapse into a (1+1)-D Gravity/WIMP-Gravity model), whereas you used a (2+1)-D Pati-Salam Electroweak model and a (1+1)-D Cl(3,1) Gravity model. It looks like you have projected the four dimensions of Hyperflavor-Electroweak into the three dimensions of a Pati-Salam Electroweak, so you have potentially ignored details associated with my GUT’s fifth and/or sixth dimensions.
In Section 2.4.2, you implied that the E8 triality may break down. Figure 2 implies that the 240 roots of E8 may decompose as 240 = 8 x 30, and 30 is divisible by three. Are there any significant 5-fold symmetries (30 is also divisible by 5) within this geometry? My GUT theory implies five generations of fermions.
Occam ’s razor is a good philosophical approach (I also like KISS – Keep it simple, Stupid! and PhD – Push here, Dummy!), and we shouldn’t introduce more complexity into the theory than is required to explain our observations (String Theory with 10500 parameters is definitely guilty of this, and my GUT might be as well). However, I think that our approaches towards the Weak and Gravitational interactions imply that there is more to both forces, and we shouldn’t call this a TOE if these 8 dimensions imply extra dimensions that aren’t described. For that matter, can a True Theory of Everything exist in less than 26 dimensions?
Good Luck!

If I understand Lisi’s work correctly, he does not develop an ad hoc model for the spacetime of particle physics nor put a model of particle physics into a spacetime of this or any other dimensionality. In other words, he does not proceed as in string theory or in loop quantum gravity. He also does not extend quantum field theory to become a quantum gravity field theory.
What Lisi does is take an already existing symmetry group and its corresponding Gosset, i.e. a four-dimensional polytope upon which the E8 manifold is based. Then he works carefully a one-to-one correspondence between the different points marked by eight-dimensional vectors called octonions and particles with the aim of recovering the standard model and making some prediction for extending it to conform at ultra high energy to the idea of unification, by showing that all the fields of all the different fundamental interactions could be obtained from the same E8 manifold. Professor Lee Smolin an open-minded guiding light in quantum gravity concluded that it is a neat way to seek the unification of all fundamental interactions in this basically non-conventional way.
Lisi’s work is therefore combinatoric in the spirit and quite near to that of Sir Roger Penrose’s program. Also not surprisingly it does not collide with the loop quantum gravity philosophy or with the basic ideas of Mohamed Elnaschie E-Infinity theory except for not admitting irrational numbers at a fundamental level. Seen in this light, Lisi’s theory is not restricted by mathematics used traditionally in this field which is an advantage.
I think people tend to forget that the founding fathers of quantum mechanics were appalled by Feynman’s path integral and string theory took even much longer to be accepted. All what I am saying is give Lisi a chance. I am not directing this toward the young researcher but I am addressing the establishment, particularly the strings community.
As for Lisi, my only advice is that he extend combinatoric as the factorial function was extended to gamma function and topological dimension was extended to non-integer Hausdorff dimension. This would be a revolution similar to Einstein bending spacetime and making it curved.

Dear Garrett,
I think I have worked out the similarities and differences between my ideas and your ideas, and the answer is E12 with a rank and effective dimension of 12 and an order of 684. Of course, several mathematicians just said “There’s no such thing”, and maybe someone can prove that my “E12” should be defined differently, but that’s what I used for my TOE.
Your ideas inspired me so much that I had to write a new Section, reference your work, and publish the Second Edition of my book “New Approaches Towards A Grand Unified Theory”. I published this book through Lulu.com, and free partial previews of “Section 7.7 – A Deceptively Simple E12 Theory of Everything” are available through Lulu. Lulu will have the 2nd edition – I’m not sure which edition (if any) the other online book retailers will have this month.
I didn’t need any ghost particles – I was able to fill all available particle states with my SU(11) boson GUT and Hyperflavor fermions. I concluded that a Supersymmetric Exceptional group MUST have fermion singlet representations, and that these fermions become the basis vectors for the adjunct Supersymmetric representation. A simple example is your G2 of color, with 2 basis vectors: g3 and g8; twelve roots: 6 gluons, and 6 up quarks/ anti-quarks; and a 2-dimensional fermion color singlet: electron/ positron. In the adjunct Supersymmetric representation, the 2 basis vectors are now: selectron/ anti-selectron; the twelve roots are: 6 gluinos, 6 up squarks/ anti-squarks; and the 2-dimensional singlet is gluino-3/ gluino-8. When we add a 4-dimensional fermion singlet to an F4 group, then our 24-plet of fermions with a 3-fold triality symmetry becomes a 28-plet of fermions with the 7-fold “septality” symmetry that is characteristic of Hyperflavor.
Table 19 is a symbolic E12 TOE. Unfortunately, Lulu’s preview software didn’t like Table 19, so I excluded it from the preview. Dr. Robert Fisher is correct that we need a Lagrangian, but I have exhausted this month’s inspiration…
Any new ideas from you?
Have Fun!

Garrett,
An article I've read describes E8 as encapsulating the symmetries of a 57-dimensional geometric object and is itself 248-dimensional.
Do these numbers in reality refer to the number of variables in this particualr Lie group and the geometry described by it? Discussing this with a friend, there remains some confusion about how these multiple 'dimensions' relate to the 4-dimensional world we're familiar with. Are these multiple dimensions merely characteristics of this particular mathematical tool used to describe our 4-dimensional world? In other words, are they real-world dimensions or merely the mathematical/geometrical structure of the E8 formalism?
Thanks.

Dear 1/1/09 Anonymous,
Your question was an astute one, and worthy of more than a simple “yes” answer.
Lisi’s Table 9 on page 16 summarizes the 240 roots of E8. Most of these particles have an obvious meaning. Lisi dedicates 192 degrees of freedom to the three generations of Fermions. Certain relevant particles, such as the gravitational frame-Higgs, e-phi, and the generation-Higgs, x-phi, have an unclear meaning.
In his matrix equation on page 18, Lisi specifies his 8 basis vectors and thus completes the 248 “dimensions” of E8. These 8 basis vectors include mixtures of gluon 3, gluon 8, photon, Z, Pati-Salam B, a new generational boson associated with the w quantum number, and two graviton degrees of freedom (omega L and omega R).
In Section 3.1, Lisi decomposes the e-phi and x-phi terms. The implication is that the 16 degrees of freedom of e-phi yield the Standard Model Higgs plus some extra Higgs, and the 18 degrees of freedom of x-phi may yield either the CKM and PMNS matrices or something similar to the X and Y bosons of a Georgi-Glashow SU(5) GUT (similar in that these allow lepton-quark transitions, different in that they are generation dependent).
Dear Garrett,
“Yes” was a short-cut answer. I hope my answer is satisfactory. Please reply if I goofed.

Dear 1/7/09 Anonymous,
By “direction of time” are you referring to the Second Law of Thermodynamics or the Minkowski metric?
I don’t think that Lisi has developed E8 to the extent that he can answer your question. I think Lisi’s E8 has other weaknesses as well, but he has convinced me to consider the possibility of an Exceptional TOE despite my prior biases in favor of SU(N) or SO(N) GUT’s or TOE’s.
Is this a winner-take-all contest between E8 and String Theory, or could both contain a hint of truth? I’m working on a transfinite quasi-exceptional E12 because I think it is large enough to contain both E8 and a 12-dimensional String Theory.
Dear Garrett,
I need to get Exceptional TOE’s out of my system. I see other interesting projects on the horizon. Specifically, Leonard Malinowski’s upcoming paper in CS&F has renewed my interest in Dirac’s Large Numbers Hypothesis. Would you be interested in working together to develop E12?
Sincerely, Ray Munroe

Ray Munroe wrote on Jan. 15, 2009 @ 14:21 GMT
OK – Here goes my best shot at answering the Anonymous 1/07 question…
Lisi wrote down the Action S, not the Entropy S. It is simple enough to define Entropy. Following the methods of Claude Shannon, we could define S = (-k)*(Sum over i of (pi*ln(pi))) where pi is the occupation probability of the ith particle state.
The problem is deriving this from the first principles of an Exceptional TOE, but I think it can be done.
The first step is to determine the correct Exceptional TOE. E8 is nice, but E8, E10, E11, E12, E14, etc. all lead to different particle multiplets and branes. The correct gravity-brane and spinors (or twisters) will reproduce General Relativity (including Minkowski’s metric) and Dirac’s Large Number. Anything else is a waste of time.
The second step is to take the limit as this Exceptional TOE approaches E-infinity. I think this intersection is the key to the statistical nature of Thermodynamics (including Entropy) and the Path Integral formulation of Quantum Mechanics. I think that this is also the root of String Theory’s 10^500 parameters, the Planck scale, Einstein’s Hidden Variables, and Dirac’s Large Number – some of the greatest mysteries of Modern Physics. Please refer to the upcoming papers by Leonard Malinowki in CS&F for more details.
Lisi’s “Theory of Everything” is not intended to include “everything” at this point, but it (or a similar Exceptional TOE) certainly has the capacity to include such.
And I would like to restate that an Exceptional TOE is not necessarily opposed to String Theory. The correct Exceptional TOE should be able to reproduce parts of String Theory (if both the Exceptional TOE and String Theory are true, then the Correspondence Principle would demand this). The wrong Exceptional TOE will understand its deficiencies relative to String Theory and will, therefore, oppose String Theory.

You are correct that the Second Law of Thermodynamics is extremely important, and it would be relevant to understand why the 2nd law is a must.
I did mention that the Planck scale is one of those myteries of modern physics (and I goofed Leonard Malinowski's name). Yes, maybe that isn't a very good answer.
I realize that the name "theory of everything" pompously implies that we actually understand "everything", and we clearly aren't there yet. But the physics community prefers to use TOE over GUT (Grand Unified Theory) when Gravity is included.
I still think that E-infinity should be important to both of these questions.

I read 1 h ago ,on your website,some articles ,
I understand better now the globality and relation between fractals ,strings,chaos...cosmology,quantum mechanics .
I like too the correlation cosmology,quantum dynamic and the method to improve some datas .
The relations between Universe and quantum physic reality is so important ,
personally the chaos is a instant, a specific phase where Time is short .
I think that the E.infinity is interesting in math to elaborate some extrapolations and applications on technology.The ration between ln will be always in mathematic infinity with these decimal improvments ,it's the same with many ratios and numbers ,pi,gold number ,Dirac Large Number.,and many others we see the infinity but I think on thing important ,if we insert the evolution and a building in correlation with spherization for me ,that's why one day the time could stop the mathematic infinity ,time is constant but there is a begining and thus an end in uour physical universe ,of course in correlation with spherization evolution ,that's why these numbers stop their infinity ,I agree this question is a little spiritual but ....could you explain me your point of vue about the evolution correlation and the Time as a constant builder .
For me Universe will be a perfect harmonious sphere and its incredible evolutive dynamics with limits between mathematic world and physic world .Our mass Universe increase ,our energy too ,but there is a paradox with energy ,but it's an other question.
About Time ,what do you think about a begining and an end of the physical dynamic ,it will stop the infinite relative mathematique in the physical reality .?
Let's take our global Earth system ,the chaos is an human invention and not a foundamental law ,some inventions like borders ,weapons,money,economy are dedicated to disapear in Time and Space ,I see the chaos like a short instant ,a kind of foto,all systems are balanced since the begining and always return quickly to a foundamental balance,it's there it's interesting ,the link between the two worlds ,the math/physic walls and its relations.
On Earth ,many systems can be chaotics and in dangerous exponentials,but the balance is foundamental and is easier to apply.
I see fractals in our biologic ecosystem like specific codes to build some structures ,like some plants ,ice ,...in fact theirs applications are numerous indeed,thanks for that.
I think that the nature is fascinating ,so much polarized Time/Space particles and a beautiful diversity around us.Many structures are fascinatings in our ecology (AN/VEG)
Many applications exist to improve our life when we see the nature and its secrets .
Kinds Regards
Steve

Hi ,
Dear Mr Malinowski ,
Just now I finished to read your last posts (february 2009),I like this article ,because there is the correlation always with a perfect balance in ultimate particles towards a physical universal spherization .
I like read all these articles and I am happy to see all these links with the foundamental spherization .
In some days via FQXi ,I have lean a lot ,it completes the Spherization Theory .
Let's see in globality ,Smal perfect spheric symetry and spheres and its numerous interactions before the ultimate particle is a specific comportment and different specific codes to a specific comportment ,the parameters in this local dynamic are relativist ,in one word,we must focus to a perceptible dynamic where we are catalysts in physical reality and motion .
In all case dear Mr Malinowski ,I like the different methods you use to calculate .The quantum gravity is so fascinating ,so much steps and states before this ultimate coded particle ,there is a wall there too ,an other link between the limits Math/Phys .
I think that if works and rational ideas focus on a spherization logic,many accelerations of improvement and of resolution ....
The quantum dimensions and cosmologic dimensiosn are linked ,I didn't know the Dirac 's Work about the large number and the ratio ,it's very interesting ,I think these results and hypothesis can help us to find our peceptible borders and these relative limits ,always the ultimate research of truth like your works Mr Malinowski about quantum gravity which I have read this day on your website.
What do you think ?

I am greatful that scientists are starting to think about infinity and time and that my ideas seen usefull. I have always believed there can not be limits to size, smale or large. The universe must exist everywhere and all the time. All scientists are taught that they can not visualize the happenings inside the atom, nor can we visualize the other side of the Big Bang. Science is like a train, with everyone inside not ever allowed to open the windows and look out. You can't see out the window. So I got off the train, and walked the tracks for 23 years.

Dear Mr Malinowski ,
Thanks to answer me and nice to meet you .
You say a important thing,
You can't see out the window.I agree with this idea ,some secrets shall stay .Our limits always and our rules of catalysts .
You say
"I have always believed there can not be limits to size, smale or large. The universe must exist everywhere and all the time."
Yes indeed ,if we take the univesal link between math/phys world .
You say "All scientists are taught that they can not visualize the happenings inside the atom, nor can we visualize the other side of the Big Bang."
Yes of course ,the relative responsability in fact ,these limits are unknew and it's well as that .
We are all in the train ,and in relative perception ,it's a fantastic evolution towards the knowledges and its perfect harmony.

Dear Mr Malinowski ,
I d like speak a little about the walls and our limits .
In spherization ,I think that it exists a specific spheres fractal in each particle and their spherical fractal fields and interactions ,implying many comportments.
Let's imagine our Universal Sphere and its volume at this moment ,and its dynamic of evolution(expansion/contraction) .
the groups and super groups of glaxies turn around a center of our Univere ,towards a specific spherical coded geometry in Time .I think the ultim quantum architecture is in correaltion with our future perfect sphere and its spherical system in rotation .
I see a interesting link between,evolution ,spherization,polarization,
let's admit that the Universal sphere volume will decrease towards an ideal balanced spherical geometry .
Thus in this logic space decrease ,thus pression increase ,thus volume decrease .....about dark m and dark e ,let's imagine a kind of particle in wait thus an activation concept ,this notion implies an increasing of mass towards centers in complementarity and complexification ,harmonization .
Let's imagine now the Big Bang or others hypothesis ,for exemple a multiplication of ultim particle and its coded architecture or ..... The first step is the expansion towards a maximum volume ,after the contraction towards this perfect spherical harmony thus a minimum volume ,the question is what is the sspace between spheres in this perfect harmony ,what is the perfect balance between them.This logic implies an increase of mass towards main centers in correlation with foundamental spherization .
The Dark Matter and Energy in this logic shall decrease in volume but the mass increase .
In resume all goes to the centers and the complexification .
It could be interesting to consider the different kinds of fields of rotation with contraction ,for exemple fiels 1 super groups of galaxies( correlation with the main center (too with quantum ))fields 2 +centers groups of galaxies,after galaxies ,stars ,planets.The accretion is interesting ,how will be its velocity ,its acceleration, its exponentials ??? it's very interesting .
About walls here is a global point of vue ,
The walls are everywhere ,in each particle before the unknew ,this maximum universal entropy ,in all centers behind the ultim spherical membran of the coded particle .Cosmologically speaking we can imagine a kind of limit membran ,this memebran in time will decrease in surface in correation with contraction and spherization towards perfect architecture .In fact our quantum architectuire is like a code to our future universal sphereand its galaxies in rotation (finishid ,this point is importnt that imples an end in the physical world ,the perfect harmony ,but not an mathematic end behind walls ,it's different .
In resume expansion towards maximum volume ,after contraction towards the perfect spherical geometry and minimum volume ,in time increasing of mass ,DM DE decrease (activation /pression,),complexification and accretions towards centers .It's the same logic with super groups of galaxies ,groups of galaxies,galaxies ,stars.
Thus spherical fields and its sphere volume increase the accretion and its gravity but its volume decrease(the field sphere volume) ,it's logic beacause the mass increase .
An other point is the gravity and the mass and its effects on the space curvature ,this increasing of mass too in linked with spherization because the gravity increase ,the mass too , and space spheresize itself towards universal center .
What do you think ?
sincerelly

(please delete above post because the brackets used to represent Mean for Mass do not show up and the whole post makes no sense sorry)
GOD/SUPERSYMMETRY/SUPERFLUID/ZEROPOINT/VACUUM EQUATION:
mean Mass = sum U(SampleSpace) divided by DegreesOfFreedom
( ex. dodecahedron .... meanM=U/DOF
meanM=91/13
meanM=7 )
GF SPHERE/STRING THEOREM:
U/DOF=(DOF+1)/2
( ex. dodecahedron .... 91/13=(13+1)/2
7=(14)/2
7=7 )
Works for ANY length of string or ANY size of sphere
*wink
(props to whoever defined "sample space" - that quality haunted me for years until I came across it at Wikipedia)

I may sound condesending or arrogant ... but unfortunately people capable of grasping these things are in the minority. Add in the fact that most physicists let ego rule their logic and you will understand that I face an uphill battle.
Quantum physics is an illusion. It exists in the 5th dimension called "ether" or "spirit" or "thought" or "the existential" etc. etc. I may even go as far as to say that the 5th dimension (quantum realm) can only be known in "cyberspace".
Its the "esoteric" realm ... like astrology, numerology, or tarot cards ... something ruled by patterns but it seeks to end "freewill" and it believes in "fate" (determinism if you prefer). Its what's literally known as "black magic". All illusion.
Science and true physics on the other hand are "white magic" and based on truth. Any serious philosopher knows the fundamentals to knowledge require the understanding of the "Heisenburg Uncertainty Principle" which basically states that "nothing can be measured perfectly because the measurement/measurer effects the outcome". Ever heard of a band called "The Perfect Circle"? True measurement or things like zero do not exist! ...did you know in medevial times that any discussion or belief in zero was cause for arrest or put to death?
Quantum physicists are trying to break the laws of reality and create "free energy/zero point energy" when any intelligent physicist or philosopher knows that the best we can philosophically ever do is 99.999~ effeciency!
Its all about the "god particle" called the Higgs Boson ... yet here's where I find extreme irony ... I'm an Agnostic ... I know that god is suprarational and "unknowable". You cannot prove god exits because god is inconceivable. I do believe in the "possibility" of god and I am extremely religious but I know an incarnate living god is IMPOSSIBLE.
Here's the irony ... I am astounded when I find a person (typically an athiest) who is absolutely certain a Higgs Boson can be proved to exist YET IN NO WAY COULD EVER CONSIDER THAT GOD CAN EXIST. The Higgs Boson and an incarnate god ARE OF THE SAME PHILOSOPHICAL CONCEPT!
Now I am not saying quantum physics doesn't have its uses ... but what I am saying is that I can evaluate a persons intellect simply by knowing if they know the possibility of what can and cannot exist in such examples as supersymmetry, zero, a perfect vacuum, a perfect superfluid. All these things CANNOT EXIST IN REALITY AND ONLY EXIST IN OUR THEORYS/THOUGHTS/ON PAPER/IN THE 5TH DIMENSION!
We live between the 4th dimension(time) and the 5th(quintessence/ether/dreams/thought/spirit etc. etc.)
My "god' equation is a very pompous title ... its more literally the description of the perfect supersymmetrical dimension, superfluid, or zeropoint vacuum.
I consider my "GF String/Sphere Theorem" the "Pythagorean Theorem" of the 21st century. Its based on any length string or any size sphere!
Try and think of an equation that adds as perfectly as mine does AND YET STILL APPLYS TO BOTH STRINGS AND SPHERES!
I face an uphill battle against quantum magicians and simpletons too uneducated to grasp the beauty of my theoretical equations.
I just want some support. Theres more than just math to this ... ITS ALL POLITICS AND QUANTUM PHYSICISTS SUCKING UP FUNDING MONEY FOR THEIR HUMMERS AND CHEESEBURGERS FOOLING UNEDUCATED BUSINESSMEN INTO THINKING THEY CAN DO "MAGIC" ...
Please spread the word about my equations. I am ready to straighten out all the bs goin on.

Garrett,
I am not adept at these very advanced maths - blame my aberrant schooling. I envy your skill in the advanced maths.
Now, I understand the idea of a "principal bundle" in terms of kinematic constructs, with each particle field represented by a resolved tensor vector, and thus the bundle would be a group of particle fields (with each field represented by a resolved tensor vector). And my understanding is that a "group dance" corresponds to the interactions of all the particle field tensors in the group. My understanding is that our knowledge of the particle field tensors that have already been 'measured' allows the prediction of the existence of unknown particles on account of the force/vector discrepancies in a given group.
My question is:
Do you see a hierarchy of the particle field tensors in terms of what pf tensors initiate the twists and what pf tensors dominate a given group? Or, do you arbitrarily assign what pf tensor initiates a twist?
To give you a little background of where I come from - I have been working on my version of the theory of kinematic relativity. And I believe I am thus far still just scratching at the surface of the theory of kinematic relativity. My theory of kinematic relativity describes motion transformations within a 3-d space 'dimension' and absolute duration transformation along a 1-d time 'dimension'. I use the idea of a kinematic continuum as the matrix of the physical transformations (i.e., the obervable phenomena), which is why I have the idea of kinematic (i.e., kinetic or motion) constructs examined using a pure 'vectorial analysis' approach instead of the prevalent (mixed-up) 'dimensional analysis' approach.
Both my logical language and my mathematical language can be considered unconventional. But I hope you won't mind so much.
Kind regards...

GF, your formula works for any N. The (25,1) dimension has a very nice formula which works only for n=25-1. Sum the squares from 1 to 24. You will get an square.

Ya, I know my equation works for any N(dimensions). I know because I tested it to the first 300 numbers so I know its empirical!!! -I considered using the letter N for Degrees of Freedom since that implies the number of N but I was more specific and chose Degrees of Freedom (DOF). I could have used Cells but cells can be different sizes inside a shape so DOF was more appropriate.
I hope people see my equation is empirical.
I said my equation (String/Sphere Law) works FOR ANY SIZE string OR sphere so on that alone is what gets me so excited yet frustrated that in a couple weeks so far noone has realized it. Although I havent really showed this to any scholistic authorities yet.

Garett,
Could the very nice structure of the E8 have a possible geometric connection with the sub-structure of the universe? Could logic be the pre-geometric precursor to such a structure i.e. could a simple rule of logic create in an explosive process this E8 structure as a sort of fractal?
( I am thinking about the basic quantum of time evolution, a small explosion with an actual structure that translates into specific sizes, shapes and masses from sub-atomic particles to crystallographic systems…)
Thanks,
Marcel,
