A computer-generated illustration is of the E8 root system, an arrangement of 240 vectors in an eight-dimensional space. The image is a two-dimensional projection of that eight-dimensional arrangement. [Technology Review: Simplified Complexity]
A few more interesting facts about the New 'Theory of Everything', as discussed in
The model based on the E8 Lie Group seems to extend the standard model of nuclear physics to include gravity.related: Lie group - Wikipedia, the free encyclopedia
Lie groups are continuous groups such as the group of rotations of a sphere or a torus.
E8 is known as the exceptional simple Lie group and is the largest of this category possible. Anything larger has infinite dimensions.
The full structure of E8 was only revealed in March 2007 after hours of computation on a Super Computer.
The new theory could be complementary to String Theory because string theorists were already looking at E8
At first glance this model might appear to be similar to String Theory because it involves an eight dimensional manifold, but a deeper analysis reveals that it will lead to physics quite unlike String Theory.
Extending Quantum Field theory into the E8 structure envisaged by Lisi would lead to a new physics very different to string theory.
