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, electroweak, gravitational, the frame-Higgs and three generations of fermions related by triality. The interactions and dynamics of these 1-form and grassmann valued of an E8 superconnection are described by the curvature and action over a four-dimensional base manifold.
