A New TOE Speaking E8



According to a new proposal by American physicist Gerret Lisi the above equations may be the answer to the ultimate theory in Physics, the unification between quantum field theory and general relativity or Theory of Everything, as is most commonly known.

Here's the abstract from the arxiv.org paper by Gerrett Lisi:

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.
