Abstract
We consider a straightforward extension of the four-dimensional spacetime M_4 to the space of extended events associated with strings/branes, corresponding to points, lines, areas, 3-volumes and 4-volumes in M_4.

C. Castro: E8 Geometry of Cl(16) Superspace Grand Unification

The Exceptional E_8 Geometry of Clifford (16) Superspace and Conformal Gravity Yang-Mills Grand Unification

June 2008

Submitted to: Int. Journal of Geom. Methods in Mod. Physics

Abstract: We continue to study the Chern-Simons E_8 Gauge theory of Gravity developed by the author which is a unified field theory (at the Planck scale) of a Lanczos-Lovelock Gravitational theory with a E_8 Generalized

Yang-Mills (GYM) field theory, and is defined in the 15D boundary of a 16D bulk space.
