It's scarily complicated.
Event the abstract leaves me a burbling wreck:
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.

Above is a comment on the article on page, where there is also a link to the paper. The other comments are worth looking at ...

Above is a comment on the article on page, where there is also a link to the paper. The other comments are worth looking at too - including the ones about mandalas, Saint Hildegard, and other stuff. But I do like the fact that this theory is testable, acknowledged as needing developmet, and produced by an independent mind. I still have to fathom why his surfing dude status is relevant!
