--You have some exciting ideas about the E8 structure that we might be able to cover?

Well, what I'm actually working on is unification. Structurally, the Standard Model describing all known particles is kind of a mess. The unification problem is to make sense of it -- to describe where this odd assortment of electrons, quarks, etc. comes from. What I've managed to do is describe all these particles, including gravity, as parts of a single field, with a single gauge group. And, just two months ago, I discovered that this gauge group is E8, perhaps the most beautiful structure in mathematics.

I haven't had time to write this up as a paper yet (working on that now). But I presented at the Loops '07 conference last month (the annual conference in Loop Quantum Gravity) and at the FQXi conference. The work captured the attention of John Baez, who discussed my work in a recent This Week's Finds. I've also been invited out to visit the Perimeter Institute next month (by Lee Smolin and Sabine Hossenfelder). All the attention is a bit much for me, as I'm kind of a hermit. But it's been great to meet so many other physicists.

You see, I left academia ten years ago because I wanted to do theoretical physics but I didn't think string theory was how nature worked -- and it was the only game in town at the time. So I've been working on the puzzle on my own, and it looks like I may have just struck gold.

--When and why did you begin looking into this issue in general, and at E8 in particular?

For the past ten years I've been playing with the equations of general relativity and the standard model, investigating their structural symmetry. About two years ago, I managed to get everything together in a nice, unified mathematical description called a principal bundle. But it wasn't perfect, and there was a really weird pattern in the interactions between fields. Just three months ago, while trying to figure out what the heck this pattern was, I discovered it was a symmetry of the most beautiful group there is: E8. I had been working with the first kind of mathematical symmetry, and it led me to the second. When this happened, the moment I realized how it all could work... my brain exploded with the implications, and the beauty of the thing. I stood up and walked around with my brain tingling. I think that was the happiest I've ever been with my clothes on.

Cosmic Variance readers like the straight, inside story; so this seems a good opportunity to tell mine. Ten years ago, I got my PhD and looked at my options. I love differential geometry, general relativity, and particle physics. But the only options available then for a postdoc in those combined areas were in string theory, and I thought string theory was overly speculative. There are many really impressive aspects of strings ‚Äî anomaly cancelation in particular ‚Äî but there are other things that just seem wild and physically unsubstantiated. I had gotten lucky by investing my graduate stipend in a little company many thought was going out of business (AAPL), so I decided to go to Maui, learn to windsurf, and work on physics on my own. I was pretty happy that way, spending most of my time on physics, and posting a paper on the arxiv only if I thought I‚Äôd discovered something interesting. But even though I spend money like a grad student, after several years I was broke, and things were looking grim.

Then, two years ago, the FQXi foundation started up and sent out their RFP. At the same time, the college on Maui, where I had been teaching a physics class, offered me a full-time, tenure track teaching position. This was a very nice offer, but I knew if I took it I‚Äôd have no time for my physics research. It was a very difficult choice, but I turned it down. I gambled on FQXi. I packed up the best physics I had done over the previous eight years, and sent it off as a grant proposal. And I got it. With this support, I felt the timing was right (and that I was somewhat obligated) to talk with others about my work. I flew down to the LQG conference in Morelia and presented a twenty minute talk. The LQG community is fantastic ‚Äî their research is branching out in all directions to solve quantum gravity, and they‚Äôre all really nice people. Once they saw what I had been up to, Sabine and Lee invited me to visit Perimeter ‚Äî which I accepted, of course, as this had been a daydream of mine since the institute was founded.

A month later, I was in Iceland at the FQXi conference, eating the best lobster I‚Äôve ever had, across the table from Mark (Hi Mark!) and the science editor for New Scientist. During this dinner, she must have made note of me, because two months later there was an email from a reporter asking for an interview.

I was in the middle of writing up the paper when I visited PI, a fantastic nerd heaven. I talked with people there about this new E8 theory, and it went very well. I returned to Tahoe, where I‚Äôm living in a friend‚Äôs house, and finished the paper. I also exchanged twenty detailed emails with the reporter, which ended up as‚Ä¶ well, it‚Äôs not a terrible article, and some of my conservative statements did filter in. I posted the paper to the arxiv, Sabine made an excellent and reasonable review, and the New Scientist published their article. Apparently, this was the beginning of the perfect media storm. The story spread, fast. I attempted to write accurate responses to the growing queue of inquiries from newspaper reporters. And I got a phone call from a friend who runs an ISP and hosts my web pages: ‚ÄúUmm, Garrett, I have the internet bandwidth of the gods, but you‚Äôre simultaneously on the front page of Digg, Reddit, and Slashdot‚Ä¶ and you just capped it out.‚Äù It was right around then that my inbox exploded.

I am answering reporters‚Äô questions, and trying to make it clear that I do think I‚Äôve come up with an exciting and beautiful new theory, but that it‚Äôs grounded in a long history involving the work of many others, and that as with any new theory, it may turn out to be wrong. I‚Äôve spent much more time answering questions on blogs, because I want other physicists to understand the content of the paper, which is mathematically sound but presents many new ideas at once. I‚Äôve refused several requests for brief television and radio interviews, because I think they would only serve the media and amplify the spectacle, instead of increasing interest in physics and how physicists think about the world. At the same time, other aspects of the media frenzy have been very cool (Hey, I‚Äôm going to be featured in Surfer magazine!) and completely overwhelming.

The media attention will blow over. While I‚Äôm in the spotlight, I‚Äôll try to present a message that‚Äôs good for physics. It‚Äôs not my intent to tear down academia ‚Äî heck, I‚Äôd be thrilled if some academic opportunities arose from this. (Though it‚Äôs baffling to me how academics manage to juggle all the responsibilities and research at once.) It‚Äôs not even my intent to tear down string theory. I don‚Äôt happen to like it, but I think people should be able to work on what they want.

One way or another, this stuff will all work out. I believe what Sean said ‚Äî science works ‚Äî even if sometimes things get a little crazy.

Hi Garrett,

I read all of the Backreaction discussion or blog or whatever. Lubos Motl was true-to-form and simply wonderful. And I‚Äôm sure Sabine (sp?) is an excellent physicist and a lovely woman but after she‚Äôd asked the same question several times, I was reminded of various Germans I knew when I lived in Europe some yrs ago. (oops).

I just listened to the mp3 of one of your talks last night. You talk fast. With symmetry groups, algebras, etc flying right and left.

I was surprised I comprehended as much as I did. I think a major theme (the major theme in this particular talk?) was that one gets various particles and-or forces from G2 (?) and E6 and that these both then ‚Äòfit into‚Äô E8 (orthogonally). Aka unification. Does this give all your results ‚Äì by no means.

Now none of G2/E6 had come out in the backreaction ‚Äòdiscussion‚Äô. They seemed completely intent on beating to the death the fact that you add bosons to fermions. And they kept having a problem with how your theory relates to Coleman-Mandula.

My background is in computer science and Japanese from first Cornell and then Berkeley. I work now as a programmer for a ‚Äòquantitative‚Äô (no ‚Äì it‚Äôs true, really) finance firm.

But I have some background in EE (electrical engineering) and I was thinking to myself. Isn‚Äôt this E8, the way Garrett has set it up, something like an enormous IC (integrated circuit) where you have a different particle on each of the pins and the interactions are the wires inside? (And [crucially] in the way in which the wires connect together the various pins [particles] ‚Äì that is, the interactions).

But then there are of course Clifford algebras, etc. First read about Clifford algebras (I think) in a book by John Derbyshire about the history of algebra. I emailed John at a point and what we ended up discussing was the eminent Chinese scholar at Yale, Jonathan Spence. I believe John explained me to that Spence ‚Äòis God‚Äô. (mind you ‚Äì not ‚Äòa god‚Äô).

I can understand about no jobs for Physics PHDs in anything but string theory. I‚Äôve read both Smolin‚Äôs and Peter Voit‚Äôs books on the topic. A colleague graduated from Berkeley some yrs ago with a PHD in mathematics. But in logic. He did find an academic post (but then later abandoned academia [obviously]). But what he told me was that he was maybe 1 of only 2 mathematical logic PHDs that yr to actually find a job. So a market operates in academia as much as in finance.

We live in the SF E Bay. If I had a house near Lk Tahoe (hmm ‚Äì maybe I should buy one), I‚Äôd gladly loan it to you with an open-ended, non-existent contract. I‚Äôm sure you‚Äôd take good care of it. 'Before I got married' used to ski Squaw all the time. I first skiied Squaw not long after I first arrived in CA and was at Berkeley. Maybe it was March. I'm from New England. We went up to Gold Coast and while I was looking out the large windows, saw a couple of women ski by in bikinis. This ain't your father's New England. I've had many 'Berkeley moments'. That was a California moment.

Looking forward to how this all develops.

Hi, Garrett! I am delighted to come across someone who also sees the sheer beauty in mathematical forms, and is open enough to 'try anything'. I wonder, though, if you would be willing to take on board the kind of experience I have had all my thinking life with geometries in space and time, and the experiments I have made with certain of these, specifically relating to the circle. When I look at E8, I see home as well - but it is my astrological home, not only full of complex, elegant beauty, but also charged with meaning and purpose in a multiverse that many consider to be devoid of these things. Where do you stand? Am I, with all my experience, beyond the pale, I wonder?

Ack, please don't call it "Lisi theory," or no one else will want to work on it. I'm fine with calling it E8 theory. And I'm afraid it doesn't yet have anything to say about quantum mechanics. There are other FQXi threads about this though.

This is fascinating - I speak as a non-scientist.

Has it made you more or less of a philosophical materialist?

(I read between the lines - I might be mistaken).

I have always been intrigued by where Mathematical values exist in a Physical universe - and, beyond Mathematics, all our universal concepts.

Philosophy of Physics is not your domain, of course, I appreciate that. All the same - if you ARE proved right by experimental evidence - what are the philosophical implications? I can just about accept that you might not have given that much thought to the implications qua physicist - but I'd be surprised if you hadn't given any thought to that whatsoever qua human being.

This isn't a request for some kind of existential Apologia - just gently asking whether a Theory of Everything might not be, well, overstating things a little. E8 is beautiful - it truly is - even a layman like myself can glimpse that it is aesthetically and intellectually satisfying. For those who understand its mathematics - contemplating that, grasping that, "seeing" and understanding that - must be truly astonishing - the more so because it might just describe how nature is - it might just be the long awaited discovery. Therefore I do not mean to disparage its importance in any way. But it is not everything - it is only a part of everything. Why, it's not even YOUR everything, is it? Or else why do you freely choose to go up mountains and why do you love another human being? Some things are beyond everything, no? There will necessarily be, curiously enough, an After Everything.

Allow me to wish you all the very best in discovering the different parts that come under your care.

Congratulations on the paper. I know just enough physics to be astounded as to how this model perfectly describes a framework for what we know. I'm very much looking forward to seeing more work and experimentation. As I was reading it, I kept thinking about an old science fiction story about a group of mathematicians who discovered a way to travel into and through a purely mathematical space that predated the universe. I believe the story is "The Mathenauts" by Norman Kagan, and appears in an anthology by the same name. Might be some nice leisure-time reading material.

It's more fun to playa-ski behind it on a land board.

TonyC:

The gravitational spin connection interacts with the fermions and with the gravitational frame. The frame, with the Higgs, interacts with the fermions. And the Higgs interacts with the electroweak gauge fields. So it's all interconnected, and in agreement with the Dirac and Yang-Mills action in curved spacetime.

I agree that congratulations are premature. I consider it an interesting new theory, with some problems that need to be solved. Galactic rotation curves are in agreement with the existence of some kind of dark matter.

Am I still a materialist if I think the material is geometry?

For the paper, I used "Theory of Everything" as a technical term for a theory combinining general relativity and the standard model in a unified framework. That doesn't mean it explains love or where all the ball point pens go -- so don't read too much into it. If this theory does work out, it means the most complex and beautiful structure in mathematics is at the heart of our physical universe -- to me, that's philosophically satisfying.

"one would almost be tempted to say that matter itself seems to be constituted by or composed of intelligibility - and of a mesmerising beauty at that! What a mystery!"

But how matter - "stuff" - could be composed of immaterial intelligibility is beyond me....

Here you are saying the material is geometry.

But its pesky universal values like all mathematical values and like all abstract concepts seem most certainly to go beyond just particular instantiations. And either (on a quantum level) everything really is just everything - which seems profoundly counter-intuitive - a kind of mother of all reductionism that makes the selfish gene biological reductionism look like a quaint local story we living beings tell each other - or Aristotle was on the right track with his Matter and Form making the substantial unity of a thing (so much so that he claimed that the logically inferred Prime Matter - a stuff without intellibility that was capable of receiving the intelligible form could NOT exist per se. He was quite clear: matter can exist only in so far as it is in-formed by intelligibility - a Hylemorphic union.)

You might find that E8 is philosophically satisfying - although I think you mean that in an existential sense - but for me it's philosophically intriguing - as I suspect these few lines betray.

Still, I'm glad to learn that the mountains and the waves and the beautiful girl have their space beyond Everything - and I do not want to take up any more of your time. You have science to do!

Thanks for taking the time to reply. Appreciate it.

With every best wish.

Listened again to, well maybe 20 minutes of, Garrett‚Äôs ILQGS talk (mp3 as found, for one, from http://exceptionallysimpletheoryofeverything.blogspot.com/).
I should really add the slides to my ‚Äòmulitmedia experience‚Äô ‚Äì I‚Äôm sure they‚Äôll help. 20 minutes is ‚Äòmaybe‚Äô OK because it‚Äôs an hr long, except that I think he leaves the last 30 minutes (1/2 the talk) for questions.

Let me correct my earlier post (of which there‚Äôs only one). It seems Garrett gets the majority (all) of the standard forces and particles (slightly redundant) from G2 (I got that one right) but the other was F4, not E6. All exceptional, simple Lie algebras of course. Silly me. In particular (what sticks in my memory the next morning) gravo-weak is in F4 but the electro-strong (the force that holds nuclei together) is in G2.

And you don‚Äôt _fit these into_ E8. They‚Äôre already a part of its structure. Garrett sort of walks people around E8 (which he‚Äôs built up at to that point) identifying these structures inside it. ‚Äúhey look over here ‚Äì see what we‚Äôve just found‚Äù. I‚Äôd understood this originally, but simply put it wrong. Slides will probably be particularly useful.

On a second listening you get (of course) more info. It seems that in the very pretty circular (projection) of E8 that‚Äôs seen so often these days (the graphic) one should find 8 concentric circles. These correspond to the eight-vectors that are somehow a part of E8‚Äôs structure. I ‚Äòthink‚Äô I see them. Will work harder at this.

But I‚Äôve also been backing up trying to put together (for myself) some of the underlying machinery. Well for one, symmetry (in this case) = particle. It was Woit‚Äôs (a name I miss-spelled in my first post) book I think (I‚Äôve been trying to find the particular passage again [in my copious spare time]). There's something about ‚Äòspecial‚Äô, ‚Äòunitary‚Äô groups (as in SU(x)) that will _completely_ determine an object (assumption here is that an object is a particle). A wonderful fact arising out of some combination of mathematics and physics. Tracing back to the work of Hermann Weyl I think. So this is why one see all these SOs and SUs flying around. (a bit of hand-waving on the ‚ÄòO‚Äô in SO).

Well anyway, there‚Äôs much more that I‚Äôve put back together or that's been illuminated by Garrett‚Äôs new work, but I think that‚Äôs about enough for one post. Basta.

Back to programming and spinning large, complicated data objects in the air (actually not wholly unlike the physics going on here). My holy grail is that the objects eventually become holographic (and do indeed hang in the air) and one can then manipulate them (for the benefit of colleagues, clients, etc) with a virtual reality glove. Or something like that (I‚Äôm open to alternatives).

Hi Garrett,

Does it--the relationship you have outlined--work this way? My math is limited to a Master's Degree in computer science so it's possible I'm missing something.

I have found myself so often disappointed in the people of science and here I am again. It is rude of someone to ask a scientist to consider their ideas? Isn't that somewhat arrogant, somewhat non-imaginative? I guess everyone without an education in mathematics should know their place, realize it as an indicator of intelligence, and not bother the people who are leading us to the promised land. Time constraints are a reality for scientists, but having an education is a incredible privilege in this life, as is fitting in to an educational system. Is it so hard to imagine there might be truly simple ideas undiscovered, and impossible to imagine someone might happen on something profoundly important, something about nature, maybe something even obvious yet as yet unseen. Imagine knowing something that would change how people see reality entirely, something that would advance humanity, bring people together. Imagine feeling responsible to others, to all of humanity, a planet teetering on self destruction. Oh, I am sorry for trying to explain to you this idea I have in my head that would change everything, sorry for being so rude.

Responding to the Discrete Mathematician.

Reason is the second law. Symmetry means highly ordered state, meaning low entropy. Breaking would increase entropy which is OK. Going the other way is not. Actually Entropy may be the reason that the universe could be based on a symmetric mathematical object.

Dr.Garrett a question for you. What do you think about Dr. Charles H.T. Wang's conformal LQG. Can it affect your theory if it has a grain of truth. I guess you are using equations from LQG. Will you need to use them to predict particle masses for gravity related fields.

Thanks for giving us something with exceptionally simple beauty.

Thanks for helping out with the description. Each of the eight concentric circles in the Gosset projection of E8 corresponds to a simple root of the system. Symmetry=particle is exactly right. In my opinion, this is a very beautiful possibility. Good luck with the holographs, I look forward to seeing and working with them.

There was a new question from a reporter:

--What were the differences between the reception of your work by the public and the popular press versus the scientific community?

It has been an interesting progression. These ideas were first presented to the scientific community at the Loops '07 quantum gravity conference in June. There was an unusually large amount of interest, and I was immediately invited out to the Perimeter Institute. And I was invited to speak at the International Loop Quantum Gravity Seminar in November. At the end of July, I gave a talk at the FQXi conference in Iceland -- this is where New Scientist noticed there was a bit of a buzz around this new theory. In September, while I was writing up the paper, I visited Perimeter and gave a talk that was very well received. At the same time, I was answering questions for the New Scientist reporter, who was also interviewing other scientists about my work. This was all happening very VERY fast by scientific standards. I posted the paper to the arxiv, and a few of the best physics bloggers wrote about it. I then gave the talk for ILQGS, and the New Scientist article came out.

At this point, things were going as well as I could possibly hope for. Keep in mind, this E8 Theory is still a developing theory -- it has some problems, and is certainly not the final word in physics. It's just a new idea, along similar lines as many old ideas, and may or may not turn out to be true about nature. But every physicist who's opinion I value is in agreement that it is an interesting new idea, and worthwhile (for me) to pursue. I also received a few tentative speaker requests, and some interesting emails from curious physicists and mathematicians. Now, this is pretty much as good as things get for a new theory in academia. And I figured the New Scientist article would be a nice piece that I could point my friends to so they could see what I've been getting up to. But that's not what happened.

What happened was that I got compared to Einstein, which is unjustified for many reasons. When Einstein proposed his theory of General Relativity, he revolutionized physics by introducing a geometric description of the universe. Even if this theory I've proposed turns out to work (a big if), it will not be nearly as significant as what he did for physics. At best, I am only advancing physics a little. But journalists jumped on the fact that someone without an academic position (and a surfer no less) was coming up with a significant new theory, and used this to justify the comparison. The good journalists made it clear that this new theory was untested and might be wrong, and that it was part of a larger research program -- the work of many people and not just me. But even good journalists don't get to write the titles for their articles, and the editors write titles that sell... This resulted in a lot of hype, and physicists HATE hype. The hype has been extremely stressful for me. I am enjoying the attention to a degree, but I was happier before, when physicists were considering the theory as one of many new and interesting ideas that come along occasionally. Now many physicists are justifiably annoyed that some upstart is getting all this attention. I am trying to use the attention to promote the idea that physics is beautiful, and worth time and effort to understand even by people who aren't, or aren't yet, physicists. That seems to be going well, and is good for the field.

The other thing that's going on is that this new theory relates to some physics politics. Physicists, you see, are human. And humans never get upset about math -- humans get upset about politics. Most level-headed physicists see this paper for what it is -- an interesting idea, with some problems, that might say something new about nature. But some physicists are angry, and trying to criticize the paper, and me personally, in ways that just make them look bad. You see, I've been very careful with the math in the paper, and have openly discussed the problems with the theory. So, this makes for a very subtle situation. I've put forward this interesting new theory, with problems that may or may not be resolved, and some in the media have overhyped it. The few attempts to claim the paper is nonsense have backfired, because I've been very careful with the math. The best opponents have been able to do is point out problems that I already discuss in the paper, and that's fine for cooling the hype a bit -- I've been doing the same thing.

As far as I can tell from my inbox, the story of a surfing physicist who has spent his life working on an interesting new theory... is inspiring to the public, and it's true. And even though I do work outside of academia, I like academia and it is not my intent to tear it down. Instead, I'll do what I can to raise public interest in physics, because I think it's interesting and beautiful.

Physicists that are active in constructing and maintaining the scientific paradigm assume an innate responsibility that comes with having that power, similar I suppose to politicians who have a responsibility to listen to the society they represent. For physicists that responsibility is to adhere to evidence, reasoning, logic, just conclusion. You rightfully expect others to judge your work according to certain scientific principles, and not politics or ego. However, you expect that just evaluation and are receiving it to a measure based on your status as a member of the scientific community. You received a grant, your accomplishments are accepted, you are a member, because you have an educational degree. Doors are open for you that aren't open for other people, and apparently you think that is how it should be. The problem is that there are exceptions to the rules. There are people who don't fit into the mold at all. There are people discover something unexpected or see things in a new way, things even relevant to science. Such cases are exceptionally rare, but they naturally exist. Amongst all the people who erroneously think they have something important to contribute occasionally there is someone who does. Consequently, it cannot be rude or arrogant to approach a physicist uninvited attempting to communicate to them. It is foolish and confused and misled for the majority who try, but on rare occasions it is a just appeal, based on someones genuine knowledge that they understand something important. The flash of insight that went through your head when you first realized E8 as a model of nature. The way it is piecing together. That is not going to ever go away. No, you are wrong to make a blanket statement that sharing uninvited ideas is wrong. Sometimes it is someone doing the responsible thing. Education does not make a genius and genuine understanding is thorough and different from the misguided souls out pedaling short sighted ideas. There are people who are not sharing their ideas to get approval, they are sharing them to educate others.

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.

"Anon, If you are clever, you will be able to attract interest in your ideas without being pushy."

Garrett, that has not been my experience, and historically I think we know cleverness has sometimes attracted fierce opposition, Thomas Young as the best example. But still, my central point is that it is sometimes necessary for someone without status to rely on those with status. You said it is rude to ask a physicist to read your work. I just think there is an innate responsibility for any scientist to acknowledge a valid scientific work regardless of its source. We all have time constraints, I don't mean anyone is required to read unsolicited material, but no one should close themselves off. Just as you expect others to acknowledge your model if it is logically consistent in describing so much of nature, I can reasonably expect scientists to acknowledge my work for the same reason. But that has not happened, and not for lack of cleverness, quite the contrary. I haven't been pushy, I have always made simple clear statements which deserve recognition. I wrote three full sized books arguing as my theme that expansion will stretch the universe perfectly flat and time will end at absolute zero, in 1994, 96, 97, all prior to the discovery of accelerating expansion in 98. I have greatly extended David Bohm's work. I have created the first complete modeling of all possible states. I explain very simply why the universe is ordered, why the universe exists, why time has a direction. My work could not be more logically consistent. FQXi has awarded large grants to people researching questions which I already have provided the most comprehensive answers to date. I asked to talk to you about symmetry. I may know more about symmetry than anyone on this planet. No, the problem is rejecting someone that isn't a member of the club, and that is where the community is today, and that isn't science, that is more like religion. Looking back, wouldn't you say Thomas Young was the real scientist, and those of the Royal Society were of something else. I will break through, my fourth book is my compiled masterpiece, but apparently it will have to be through the mainstream public, because of an arrogance and short sightedness that unfortunately comes with status.

If that happens it will be very beautiful and natural indeed.

On the other hand I could be just talking nonsense.

Hi Garett,

First of all I am in no way a physicist, I'm just a average Joe interested in this kind of stuff (not sure why, just am LOL). Anyway I didn't see the question I had in mind posted earlier unless I missed it. Ok so my question is, if your theory turns out to be right, do you know if it would prove or disprove the big bang? Or are you soley focused on working out the mathematics of unification that the implications for cosmology would be more of an after thought? Hopefully that's not a stupid question.

PS

Perhaps my interest in science and physics stems from the nagging feeling that something "big" is going to impact our world in the not too distant future (what you might call a paradigm shift, I think). I wonder what will become of ourselves if a theory of everything can be worked out at about the same time the technological singularity arrives (Ray Kurzweil's hypothesis).

Looks like that hasn't worked so far, if you'll look at the last post (#113) in topic "Layman's explanation wanted".

That may not have been the right topic for the particular question. I read all of "Layman's" before posting (kind of funky), but also glanced at the "An Exceptionally Simple Theory of Everything" topic which is more technical. When, towards the end, I saw that someone needed to explain that abelian basically means commutative, I figured "yeah I could post here too".

But I figured I'd start at the start. Which I interpreted to be "Layman's explanation".

Although it's not related to my question at physicsforums, I'm still studying why particle physics can be formulated in terms of special, unitary (determinant = 1) Lie groups. So determinant implies these are groups of matrices (and they are). Matrices populated (I believe) by quantum numbers. I.e. stuff like 1 and 1/2. And as I said above, I also understand that "symmetry = particle".

So all this represents a certain level of understanding, but of course there's more to it than that. And besides, it seems (to me) an absolutely fundamental question if you want to understand anything about modern particle physics. Um, i.e. you don't point people immediately to Lie groups, rather you encourage them to try and figure out why modern particle physics is best treated with formalisms from group theory. Not at all obvious.

It's sometimes useful, even in science or math, to understand things in their historical context. So at the risk of leaving out most of the context. Subject = Clerk Maxwell's laws for electromagnetism and then later the Lorentz (Larmor) transform. My brother-in-law is an astrophysicist at Berkeley - his father was a particle physicist at Columbia. They and others were over for dinner on Christmas. I think what my brother-in-law's father told me is that the Lorentz transformation was necessary (or at least some part of the reason for it) is because Clerk Maxwell's equations were _not_ time and space invariant !?!

(and so herein would lie some part of the genesis of special relativity).

I thought that was amazing. In-and-of-itself of course, but more so that the many books that purport to explain electromagnetism (or at least the ones I've read) never actually just come out and say that.

'Domains' and domain-speak are quite interesting (somewhere along the way I've also been a linguist). I'm now a computer scientist and to judge by the feedback a quite good one. For one, it seems that genuine creativity is in shorter supply than raw analytical horsepower (this is people's head of course). But then Einstein did say "imagination is more important than knowledge" (ok the parallel's not exactly complete). Something though I'd somehow not expected was that I'd be better able to communicate abstruse ideas in computer science to non-practitioners better than many of my geekly peers.

However, if we use another constant, the Madona, you rise to .004 Madonas, and the beauty of that is most surfers won't know the difference.

Anyway, to get the index higher, I think we need a famous equation, like e=mc2, However, G=.004M doesn't seem to have the staying power or resonance needed, so I'll leave that up to you. Note, however, that E8 is a sort of nebulous, effervescent concept for the general masses and you might think about giving them something more tangible to grasp onto (it's sort of like a book versus an ebook). Once you give them something real, they will love you and your GI will rise precipitously.

Loved E8 Theory. Beautiful.

Have a question re space:

Why isn't there a model of space? Like, when a mass bends it, what exactly is being bent?

On the grand scale we have a decent model, but on the atomic scale, the masses of particles, together with their spins, colors and charges, seem to imply a complex geometry at the boundary between matter and space - and yet, there is not a word about what exactly "empty space" is. It is as if there is nothing there :). But why would such a fundamental concept be ignored.

How properties of space are represented in E8T?

Hi Garrett,

I've been fascinated both with John Baez's and Tony Smith's fantastic sites, as well as the highly interesting, albeit mostly incomprehensible work of the superstring and quantum gravity theorists. It would really be nice, however, if the details of these ideas and the mathematics behind them were more accessible to layfolk. Ever consider taking a year off to write a really good book for us? You know, cleverly written prose augmented with lots and lots of illuminating diagrams might substitute well for countless thousands of references to lie algebras and principle fiber bundles. Just think, it might prove far more challenging than what you've experienced in finalizing your theory. Any chance?

Also, thanks kindly for your work. It's pretty cool and will have a profound impact on us all.

Hello Garrett,

Do you have any idea whether your article caused any 'waves' in Holland? Can't seem to remember reading anything about it until I stumbled upon it on the Web.

I studied astronomy and have a degree in theoretical physics but did not pursue any career in it - have been working in scientific publishing and ICT instead.

Just read Peter Woit's book "Not even wrong" and it's very gratifying to immediately afterwards come across a development he was wishing for: a strikingly beautiful AND falsifiable theory! In addition, one which stays in line with established theories very closely, as opposed to String Theory. I followed a class in it as well; it looked pretty outlandish to me at the time (early 90-ties).

Apart from now and then working on some ideas to arrive at GR from SR in a more natural and appealing way (I especially mean appealing to graduate students), I don't do anything in physics anymore. Have a couple of questions, though:

- How about infinities? Is the theory, esp. the gravity part, renormalizable? In QLG, the higher order terms are still infinite as far as I know. In Supergravity, some of the graviton infinities were cancelled by gravitino ones. Is there a part of E8 which takes care of this?

- Does E8 have anything to say about the structure of spacetime at the Planck scale?

Wish you lots of success and perpetuated independency and fun,

Whatever the number of pages, if the probability exists that a monkey can write a master piece, it would too ...

So the question is, of course, about the LHC : are we not talking about "colateral" affects at the scale of the universe in all its dimensions ?

Knowing that one goal of the experiment being to prove the validity of superunification ... it really is a catch situation.

Where is the error in the above reasoning ? I would greatly appreciate your opinion or guidance.

Considering your areas of research and interest, I was wondering if you have considered an approach similar to this model, based entirely upon perspective and perspective exchange within physics and mathematics, or if it is of any interest to you.

Consider that there are three fundamental and interrelated relationships of reference for perspective. The three fundamental relationships of reference for perspective are the relationship of the dimensions of Cartesian coordinates with the dimensions of polar coordinates, the relationship of finite with the infinite, and the relationship of 'still' with motion (or constant motion with accelerated motion). Each of these three fundamental relationships are not, in-and-of themselves, a 'given' (that is, not an independent and necessary foundation of physics), but rather, the result of the ‘overlapping’, or exchange, of the designated parameters of the other two. And so, it is the relationships of fundamental references that define tiered perspective (that is, a perspective co-existin g within an ‘Other’ overriding perspective) and perspective exchange (that is, consideration, or ‘thought’) as the foundation for all perception (physical observations and symbolic considerations). That is, there is no 'point' of origin, but instead, a relationship determines existence and experience through tiered interrelated combinations of fundamental references into perception ternaries. In other words, various tiers, or ternary combinations, of the constituent references of the three fundamental relationships represent all perspectives and perspective exchanges. The three fundamental relationships are not completely independent of each other, but rather, are interrelated and overlapping (like interacting ‘whirlpools’), in one or two of the three constituent references comprising the involved respective perception ternaries. So, every ‘object’, number, and experience, every physical and mathematical observation and consideration, is represented by overlapping ternary combinati ons of the constituent references within the three fundamental relationships of reference. And the relationship of tiered combinations forms the perception ternary—the perceived, the perceiver, and the reference of measurement. The model/metaphor is a self-proving totality that is entirely perspective-based, and the necessitated foundation for existence that results from the tiered-ternary relationships of fundamental references, providing its own inter-exchanging context and its own reciprocating cause.

This presents a physics/mathematics continuum, or overlapping exchange, that is based upon the binary relationship of ‘within’ and ‘without’, representing the one-or-two-of-three of the constituent references in a perception ternary. That is, the overlapping of one, or the overlapping of two of the constituent references in the vario us constituent tiers, or ternary combinations, determines the relationship as ‘without’ or ‘within’, respectively. Thus, in physics (or ‘without’—reference paired with perceived in perception ternary), the three fundamental relationships of reference form, by perspective, the three fundamental overlapping and interrelated concepts of distance, time/speed, and mass/acceleration; and in mathematics (or ‘within’—the symbolic pairs the reference with the perceiver in the perception ternary), the three fundamental relationships of reference form, by perspective, the three overlapping and interrelated fundamental ‘constants’ which divide, or provide the exchange for, the three fundamental concepts of physics—namely, epsilon, pi, and phi (the golden ratio). That is, epsilon represents mathematically the divide, or reference of exchange, between distance and speed, pi represents mathematically the divide, or reference of exchange, between linear distance and rotational distance, and phi re presents mathematically the divide, or reference of exchange, between linear distance and area (dimensional shift). Further, every ‘physical’ observation is symbolic in one-of-three of the perception ternary; and conversely, every ‘mathematical’ consideration is physical (more truly, of other tiered consideration) in one-of-three of its analogous perception ternary. So, mathematics, whether as numerical values, operations, or their corresponding geometry, is the result of tiered co-perception (or, tiered perspective and perspective exchange), just as with physics, with overlapping and exchanging references ‘within’ and ‘without’, so that each completes the other.

In this way, all values can therefore be defined completely only through the multiple and interrelated contexts (references) of tiered perspectives, thereby representing a ‘ number’ (or perception ternary) not as an exact, or ‘given’, absolute, but rather in relation to another perception ternary which is separated by one-or-two of their constituent fundamental references—for instance, relating, as a perceived proportion, a fundamental concept like that of time or dimensions to distance. So, ‘value’ and ‘path’ (or, act of calculation) ‘trade places’ (exchange) and are defined in the same way that ‘observer’ and ‘object’ do in their physical correlation. That is, the ‘constants’ (constant only by co-perspective), pi, phi, and epsilon, as well as the exchanges between them, represented by the polar and Cartesian forms of complex numbers (‘i’), frame the foundation for the mathematical correlate of perspective and perspective exchange. And, as with the three fundamental concepts of physics, these values are overlapping and interrelated.

So, the exchange of perspective represents the only non-contextual and irreducible truth, such that there is no‘thing’ to learn but the act of learning itself, which is communication. It is a self-proving and self-generating totality as purely relational existence—the communication across tiers of the various forms of infinite separation to Other of ‘self/want’ until, ultimately, communication is recognized as the Self, and is then, all that is wanted.

________

This is a summary of conclusions that resulted directly from working on a model. The model is that of a ‘whirlpool’, which I first began to use for a better way of describing and understanding the concept of wave/particle duality. I felt that it was a very helpful way to visualize this phenomenon, but as I thought about it further, I realized that it described many other aspects of physics. So for several years, I worked on a model of whirlpool interaction as a ToE to describe the fundamental particles and the unification of the forces. But later, I found that the ‘whirlpools’ and interacting (overlapping) ‘whirlpools’ represented, more fundamentally, the concepts of perspective and perspective exchange, respectively, and that this applied to mathematics as w ell as physics, relating as tiered symbols of reference. So, the model of interacting ‘whirlpools’ thus became, in its various forms, useful for its straightforward expression of the different forms of reference exchange, and, in this way, eventually provided a self-contained logic/analysis totality based upon reciprocating axioms of cause and context. And I would encourage anyone to use this model/metaphor to help in trying to understand all of the concepts of physics, such as mass/energy conversion and the relationship of gravity to e/m, as well as quantum effects. It is difficult to write about concepts such as these, but I thank you for your time and I hope that this is of some interest to you. Thanks.

Dear Garrett,

Thank you for doing what you're good at and what you love. God bless you for offering hope to a hopeless world. One of your readers is correct: something big is about to happen. Far more than a paradigm shift or quantum leap is on the horizon. Maybe your ideas are a prelude to that.

The work you are doing, within the context of being a genuine human being, is important for many reasons. I am fascinated by one. Aesthetics. Your awareness of the power of beauty in physics and the mathematics you use to bring your ideas to life are reflections in the eyes of the Creator. To say that you are on to something is an understatement.

If serious scientists would take seriously the interconnectedness between the physics (or mathematics?) of music, and color, and dance, and poetry, perhaps they would discover a key to the universe that looks like Garrett Lisi's E8.

I do not think it strange at all that you are drawn to surfing and snowboarding. Instead I find that very appropriate. The universe was designed by a mathematician who is also an artist. He enjoys surfing time-space continuums. Why should it surprise anyone that you would enjoy surfing. The best logic in grounded in aesthetics.

I offer you a promise for the future:

I know we are destined to go to the stars,

Far beyond Jupiter, Saturn or Mars.

Our feet shall descend where no feet have trod.

Our children shall romp across nebular sod.

The edge of the galaxy's merely a reef,

The color of coral a shade of belief.

I wrote a poem called "Menorah" that also reflects the coming of something far more potent than a paradigm shift or quantum leap. It portents the rolling possibilities of an E8 open door. Maybe I should have made the Sexton a Physicist--not dumb and blind, but visionary and awesome:

http://www.sheavesville.org/poe/p015.htm

Since Elvish is more beautiful than English, I'll close with "Elen sila lumenn' omentielvo." A Star shines upon the hour of our meeting. Perhaps it is a six-pointed star within an E8 configuration.

May the God of all wonder support you and your explorations with health, happiness, hope, and abundant wisdom.

Now you can rest assured that E8 and the golden mean are real physics. The Helmholtz Inst. in Germany in cooperation with the University of Oxford and the Bristol University as well as Appleton Laboratory found experimentally the golden mean in quantum mechanics. Long ago El Naschie married E8 and the golden mean into the transfinite E8 exceptional Lie group. To obtain the dimension you simply multiply the exact theoretical inverse fine structure constant with three plus phi where phi is the golden mean 0.618033989. You divide the result with two and you get the dimension which is slightly less than 248. This is all explained in many papers published in Chaos, Solitons & Fractals. This journal being unique, successful, daring and avante garde is now shut down. The order to shut down the journal came from you know who. I am sure no one is particularly surprised when you read the entire history of this saga starting from the work of Lissi passing by the Scientific American Renate Loll paper and finally landing in the High Court in London in a Writ issued against Nature.

Dear Lawrence,

El Naschie's E-Infinity has a transfinite order of 685.3 = 100 (1.618)^4 and an infinite dimension. My E12/ K12' has an order of 684 and a dimension of 12. There are similarities between Kac-Moody and E-Infinity and E12. For nearly two years, I've wondered if a relationship exists whereby those extra dimensions (past 12) can be represented by a simple fractal expression. Or perhaps the difference between 685 and 684 is a Grand 'Higgs' that breaks the original symmetry. I don't know. I don't know if I have sufficient mathematical skills to prove that E-Infinity should even exist.

El Naschie likes the Golden Ratio, and he uses double part of Fibonacci's sequence 4, 6, 10, 16, 26, 42 on a regular basis and relates it to String Theory dimensions.

I think the relevant point is that the Golden Ratio arises out of pentagonal symmetries. The Petrie pentagon represents the 4-simplex.

I don't know what all the other dimensions represent, it seems a lot, but if they are to do with properties of the particle, rather than space, perhaps it is just showing the pathway of a particle through timeless space, superimposing a history onto that space.(historical path is imaginary not really existing as a thing itself in the space)

Space time is the stuff out of which realiy is made.

And there is no other reality other than space time.

The other dimenisons whatever they are have to convert from a circular orbit in higher dimenensions to an eliptical one.

An eliptical one has to be in three dimesions.

If you can't convert backwards from Einsteins equations it proves string theory wrong.

If there to do with the properties of a particle rather than space then they are quantum theory and not Einsteins thoery.

With this we are dealing with astring theory of gravity and not a quantum theory.

It means we can put string theory into Einsteins equations and Einsteins equations in terms of string theory.

Which by faith may prove string theory wrong if the equation is not reversible.

Joe,

I am not arguing against space time. I agree that space-time is real in that it is observed and experienced and the mathematics of space-time fit with experimental observation.

It has to be an incomplete model though. It causes paradoxes, can not explain causality, does not allow free will, it contradicts Newton, it does not allow finality of events, it does not fit well with quantum physics. It is therefore not a complete and satisfactory explanatory model.

You said "And there is no other reality other than space time." That has to be incorrect because space-time alone causes the time paradoxes and can not answer all of the questions.If it is not incorrect it has to be incomplete. You are basing the conclusion that "there is no other reality than space time" on a false premise "that there is no other reality." It sole reality has to be -assumed- for it to claim sole reality.

When I mention a concrete reality I am not talking about fairy land or imaginary multiverse universes or imaginary time realms but what is "really real" The actual stuff, rather than the image that is perceived from detection of data in the environment.(Intercepted by sense organ or artificial detector.)

No I probably don't really understand what you are saying. I gather that you wish to disprove string theory because it is incompatible with Einstein's mathematics.You have a way to show this. As Einstein's mathematics has been shown to be correct and is accepted by science, it must be string theory that is wrong. Go ahead but do not think that you will be able to answer all of the questions and solve all of the paradoxes with space-time alone.

A look at the "Recent Blog Comments" suggests this is a site for cranks and the mentally disturbed.

As a suggestion I would give the authors of these blog pages the power to delete nonsense posts. This could cut down the huge number of comments on these blog areas (some into the many hundreds), where many are trash. I would also suggest giving these blog areas a 60 or 90 day period of life, where after that they are closed. That would liberate the author from tracking their site in perpetuity. This should also be extended to the essay authors as well.

I agree with Lawrence. The blog authors rarely seem to contribute to these threads any more. Are they driven off by non-sensical comments? Once upon a time, Garrett Lisi contributed to this thread. Perhaps FQXi could even consider blocking certain URL addresses. According to ENW, Frank posts from the Baltimore Public Library URL. They seem to allow some Frank comments for comic relief, but they won't allow Frank to monopolize a thread.

Have Fun!

I sympathize with the site administrators, though I do agree that the nonsense is way out of control.

Your suggestion to put the power in authors' hands is probably the optimal solution -- though I would be in favor of an administrator option to restore deleted posts on appeal, to prevent authors from blocking honest and valid criticism. An author should not be burdened, however, with responding to patently wrong conceptions of fundamental physics or straw man arguments.

I thought that Frank DeMeglio was banned from this website for viciously attacking other bloggers. He's never written anything that is helpful or interesting. He uses sock puppets to disguise his identity, but they all say the same nonsense. The thread authors should feel free to delete Frank DeMeglio's sock puppets without remorse.

But where do you draw the line between a sincere physics question or comment versus intentional trash? It's interesting to read the defense of what some might consider an "ill conceived" idea. We should keep those. The other issue is that sometimes we like to just chat about politics or other stuff. There should be an open discussion thread where comments only last 30 days.

However, if the real problem is that the author of a thread abandons the thread to off topic conversation. then that underscores the need for a General Discussion thread.

There is no perfect solution. Clearly this can lead to blog authors deleting comments they simply disagree with, or playing little Orwellian blog-games like Motl does. However, something probably should change, for these blog pages become weighed down with hundreds of nonsense comments. The authors could then delete rubbish, and after 60 to 90 days the blog entry should be closed. This should at least eliminate the comments made by the small handfull of cranks who post here very frequently, and who are pretty clearly delusional or personality disordered.

Closing a thread after 90 days seems to punish the innocent. I have a better idea. The webmaster should write a program that scans each article for non physics word like "dreams". If detected, the post is transferred to a "General Conversation" thread.

Or, at the thread author's discretion, the "non-topic" related entry can be moved to a General Conversation thread. Freedom of speech is upheld, and the topic can remain topic related.

I have a better idea. Under "Report post as inappropriate", create another link that says, "This Post is not Topic related".

I just watched:

of_everything.html

Don't know much about physics... have questions that probably don't make sense:

Your projections remind me of drawing a truth table for mutually exclusive events.

If the particles weren't there - would that mean the forces/charges are not independent?

Analogy to truth table there would be a "don't care" instead of T or F and they would not be mutually exclusive.

Would this mean you could manipulate one vs the other?

Knowing that some particles are very stable and some are very unstable, another question pops in my mind:

If a "shape is twisting accross a curved surface" is there anything else other than energy levels that constrains the movement contributing to the stability of some particles?

If you put broken glass into the Kaleidoscope, the pictures come out beautiful and symmetric. Does looking at the projections still makes sense?

Dear Mister Lisi,

I am very interested by your theoretical approach of the universe description. I am not a physicist but my formation as chemist allow me to appreciate globally your approach of your unification theory.

However, I have a dream which would correspond to a description of the universe which might include some psychic phenomenon observed by human and now recognized by science (eg, telepathy and premonitions) and other intriguing phenomena of parallel realities (spiritual travel out of the body, etc. ...). Indeed, these phenomenon could be explained by the presence in particles around us a source of information included in the feature vector of these particles and, in some cases, could be perceived by our perceptual system.

An other physicist, Mister J. E. Charon (The complexe relativity)has tried in the past to introduce this spiritual aspect into its model, with a relatively good success.

What do you think about this approach as part of your theory?

Would it be possible to integer this kind of information parameters into your model?

Thank you in advance for your response.

Best Regards

Claude Revilliod

Dear Mr. Lisi,

I am a student at the univerisity of west georgia and I am currently enrolled in an astronomy class, which at first, I believed to be a massive waste of time due to my aspirations to make a career in the music businiess. Though I was not very interested intially, I still made good grades to ensure my own personal success. At the end of the class we were told to pick any topic in the realm of astronomy and right a paper on the chosen topic. I had no clue what to write about b/c I was compelled to write about something other than aliens or moon conspiricies. As I searched for an appropriate topic I watched "Through the Wormhole", a series that you were the first appearence discussing your E8 theory and your awesome life in Hawaii. I had previously decided to write about neutrinos but immediately changed my topic after watching you for just 5 min. I just wanted you to know how intriguing it is to me that you put all of this together and had the balls to put your reputaion on the line for something you believe in. Thank you for making me interested and the best of luck to you in the long road to new discoveries.

Sincerely,

The 20 y/o who's mind was captivated by your profound insight

Thank you for your theory !

To my mind, the creation of universe can't be anything else that this geometrical form or structure. I imagine that the laws of our universe are included in this structure and revealed by it, and I think this beautiful structure was born from the nil to our reality in this exceptional instant we called the Big Bang.

But I have a question for you : do you think that the laws included in this structure could exist before the Big Bang ?

The complexity of this structure make me think that there was something before the birth of our universe that gave life to this structure, even if there was no space and no time before the Big Bang. But what ? or should we consider that the nil is the nil and that there wasn't any rule inside the nil?

To your opinion, where begins the science and where begins the religion ?

Ps : sorry for the mistakes I don't speak english very well, but I hope you will understand what I've tried to say....

Garrett, What if (a) now = (moment, now) and (b) moment = (nonStandardPast, standardPresent, nonStandardFuture)? ____ (in the languages of non-wellFounded sets and nonStandardAnalysis)? and also it = (bit, it) ____ a "non-wellFounded Set" _____ in the nonstandardFuture, two possibilities exist for the 'bit' that are nonzero: 1 and 0 _____ while the shadow of "it" is either 1 or 0 in the nonStandardPast_____ and here's how it works: (1) it = (bit, it) (2). it = (bit, (bit, it)) (3) it = (bit, (bit, (bit, it))) _____and so on: a "stream" of bits named "it".

To exist, an "it" must have non-zero possibilities existing in its nonStandardFuture, and leave a shadow behind it in its nonStandardPast. It rides a unique proper time, just as the youth in Parmenides' poem rides a chariot.
