E8 Lie group and E8 Lattice has sometimes been called the most beautiful mathematical structure in the world. Is it the theory of everything or the true nature of reality? It even has an entire research company behind it called “Quantum Gravity Research”

It is a 248 dimensional object, but it can also be thought of as an object that has 8 spatial dimensions, with 248 symmetries.
Why is this structure important? Well, it happens to show up in parts of String Theory. But also in 2007, a theoretical physicist Antony Garrett Lisi published a paper proclaiming that the mathematics of this structure contained all the particles and forces in the universe. He called it the “the exceptionally simple theory of everything” What Lisi did is he found a relationship between this object and all the forces and particles we know about.
According to the standard model, there are 4 fundamental forces in nature, strong force, weak force, electromagnetism and gravity. And there are 12 fundamental particles. In addition, each of these particles has a antiparticle of itself. In total, these make up all the elementary particles, and there are exactly 28 of them. 24 elementary particles, and 4 force carrier particles. Each of these distinct elementary particles has eight quantum numbers assigned to it, based on the charges each particle has.
This brings the number of distinct particles to 224.
Lisi found that he could mathematically equate all of these particles to one of the points in the E8 model.
But the model has 248 points, not 224. So what about the empty 24 extra points? He simply created 24 new theoretical particles.
Notice how the lines radiate from each point: Lisi also found patterns emerging between particles and forces like they happen in actual reality – for example, when photons interact with leptons, they create electrons. The same thing happens in the E8 lattice. The connections shown within points on the E8 match up to real, known connections between particles in our physical world.
One of the particles he assigned to this shape behaves very much like the force carrier for gravity – a graviton. And this is the key to Lisi claiming that this could be the “theory of everything.” – because it combines matter particles and gravity in one framework.
So Basically, all the normal things we know about can be described in terms of algebraic objects, and each of these objects happens to sit inside this complicated E8 structure.
Lisi’s theory does have some problems. One of the biggest problems with the theory is that Lisi combines the force carrying particles, Bosons with the matter particles. String theory does this too, but with the rigorous mathematics to go with it. This math is not present in E8, so Lisi combining these appears to be arbitrary.
In addition, a leading mathematician and expert on Lie groups, Skip Garibaldi wrote a paper in 2010 which mathematically disproved Lisi. But Lisi came back with counter arguments to that.
But the elephant in the room is the 24 new theoretical particles that come out of this theory. So it requires the existence of undiscovered matter. However, since the startup of the Large Hardon Collider, it is possible one of lisi’s 24 new theoretical particles could be found. Lisi himself says, “I’m the first to admit that it’s a long shot.”
In fact, I think that even if one of the new theoretical particles is found, it would be a huge breakthrough towards proving this theory is on the right track.
How does this compare to string theory? At least there is a way to prove it, unlike string theory – where we don’t really have a way to prove it.
And although E8 has a vast number of dimensions, the physical universe described by the theory would have only the four dimensions we are familiar with and not the 10 or 11 of string theory.
You may have heard of a research organization called Quantum Gravity Research. This group has built a whole company around the idea of E8 being the theory of everything. They have some really well produced and slick videos on you tube that you can check out for yourself. They are like mini movies with actors, special effects, and animations. So I commend them for making this science approachable to everyday people.
The problem with their videos is they are mixing actual proven concepts in physics with a lot of unproven concepts, including new age mysticism. This really diminishes their credibility in my view because the viewer doesn’t know which part is true and which part is conjecture.
E8 is a real mathematical structure. It has been around for a long time. Quantum Gravity Research people did not come up with it.
And I think it’s an interesting idea. All that needs to be done, is for the large hadron collider to find at least one of 24 theoretical particles, and this theory may get hoards of scientists singing its praises.
No it isn’t, it doesn’t describe gravity, I dont think it solves the vacuum catastrophe, nor explains the measurement problem or explains the lack of homogeneous distribution in the CMB, I don’t think it explains exactly what energy actually is etc etc when one sees the Theory of Everything one doesn’t ask is this it? One knows it is because It is simple and clear (in essence while very complex in the detail) .
I have it, if you want to read it I will send you the abstract and perhaps a few selected sections then the full paper if you will peer review it with a female physicist. I want a gender balanced peer review done free (I am broke) with no conditions for copyright control it must be released open source (I have been refused peer review because I am broke and won’t allow commercial copyright control). I want no leaking of the fact we have it to anyone but yourself and your partner peer reviewer before the release time.

Two things which may help you understand that I am that person with the TOE.
Energy quantised is a push.
The measurement problem, we can always only ever measure along one dimension of space and time at any one time…I can explain that further but if you can figure how simple and true that is it would assist in me having confidence in your ability to reason. The TOE calls for the ability to rethink everything you think you knew and it goes beyond physics into metaphysics to explain what numbers can’t, it has to because consciousness is an integral part of the logic of the Universe.
I saw you say in a video that you believe the person with the TOE is alive now. Your prediction was correct that in itself gives me confidence in your judgement considering so many said it would probably never be found. They of little faith.
