The cosmological one is maybe easier to realize: it considers, the current Universe generation is formed by interior of giant dense collapsar, which is behaving like black hole from outer perspective. This collapse was followed by phase transition, which proceeded like crystallization from over-saturated solution by avalanche-like mechanism. During this, the approximately spherical zones of condensing false vacuum have intersect mutually, and from these places the another vacuum condensation has started (a sort of nucleation effect). We can observe the residuum of these zones as a dark matter streaks. The dodecahedron structure of these zones should corresponds the E8 group geometry, as being observed from inside (i.e. from past perspective due the Universe "expansion").

The second interpretation of E8 is relevant for Planck scale, i.e. for outer perspective (the future). The dense interior of black hole is forming the physical vacuum, which is filled by spongy system of density fluctuations, similar to nested foam. Such structure has even a behavior of soap foam, because it gets more dense after introducing of energy by the same way, like soap foam shaken inside of closed vessel. Such behavior leads to the quantum behavior of vacuum and particle-wave duality. Every energy wave, exchanged between pair of particles (i.e. density fluctuations of foam) is behaving like less or more dense blob of foam, i.e. like gauge boson particle. Every boson can exchange its energy with another particles, including other gauge bosons, thus forming the another generation of intercalated particles.

Therefore the E8 Lie group solves the trivial question: "

*Which structure should have the tightest lattice of particles, exchanged/formed by another particles*?

*".*And such question has perfect meaning even from classical physics point of view! Such question has a perfect meaning in theory, describing the most dense structure of inertial particles, which we can ever imagine, i.e. the interior of black hole. AWT inteprets a rotation of Lie group in general reference frame, which leads to another particle generation as a Penrose-Terrell effect, formalized in Wick rotation approach.

There is no "TOE" inside E8 - well, these theorists..

OdpovědětVymazatA complex form of mathematical symmetry linked to string theory has been glimpsed in the real world for the first time, in laboratory experiments on exotic crystals.

OdpovědětVymazatRecap: E8 group geometry solves trivial question: "Which structure should have the tightest lattice of particles, formed by energy exchange between another particles, recursivelly?". And such question has a perfect meaning even from classical physics point of view! Such question has a perfect meaning in theory, describing the most dense structure of inertial particles formed by energy exchange between another particles, which we can ever imagine, i.e. the interior of black hole.

OdpovědětVymazatRegarding to recent Carrol's and Distler's critique of Garret's E8 theory, I don't understand, two things:

OdpovědětVymazat1) If usage of E8 group by Garret is so wrong, why string theory is using it too?

2) Why not to use some larger group, for example Monster group? It’s evident, real world is not just 24 dimensional (1, 2)..

Sometimes, I can't resist the comments made by Lubos, whose sole purpose are attacking some physics theories and their authors. I get angry a lot and then, without thinking, I write some offensives comments at the fast comments section of his blog TRF, which are immediately deleted by him. I have to confess that many of these comments only add noise. Unfortunately, I can't resist the lies that Lubos has written about the whole class dubbed the GraviGUT theories. E8 theory belongs to this class and as you know is the right TOE. Well, there are another theories that are close to the truth, like the SO(3,11) theory by Nesti and Percacci, but only can exist one correct TOE ;-).

OdpovědětVymazatSo, I've wrote a response to such unfair and sly post by Lubos critiquing these theories.
