Can E8 symmetry explain the Universe?

Damn clever.  A popular article and the preprint.

Lisi’s breakthrough came when he noticed that some of the equations describing E8’s structure matched his own. “My brain exploded with the implications and the beauty of the thing,” he tells New Scientist. “I thought: ‘Holy crap, that’s it!'” What Lisi had realised was that he could find a way to place the various elementary particles and forces on E8’s 248 points. What remained was 20 gaps which he filled with notional particles, for example those that some physicists predict to be associated with gravity

An Exceptionally Simple Theory of Everything
Authors: A. Garrett Lisi
(Submitted on 6 Nov 2007)

Abstract: All fields of the standard model and gravity are unified as an E8 principal bundle connection. A non-compact real form of the E8 Lie algebra has G2 and F4 subalgebras which break down to strong su(3), electroweak su(2) x u(1), gravitational so(3,1), the frame-Higgs, and three generations of fermions related by triality. The interactions and dynamics of these 1-form and Grassmann valued parts of an E8 superconnection are described by the curvature and action over a four dimensional base manifold.
