An Exceptionally Simple Theory of Everything

A. Garrett Lisi

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.

  1. The Octonion Math That Could Underpin Physics 1 comment

    • I remember hearing Garret Lisi's TED talk on the E8 ToE (link below) years ago and hoping that components of the theory would eventually come to light through advances in particle physics research. Has anyone heard anything supportive or to the contrary since? TED Talk…

  2. The LHC “nightmare scenario” has come true 1 comment

    • Add to the list Garrett Lisi's E8 Lie theory. I would hope some of his predictions are testable at some point. http://arxiv.org/abs/0711.0770

  3. Surfer-Physicist's Unified Theory Leads to Fame, Backlash 1 comment

    • Huh? He indeed does claim that his model unifies all the forces. The title of his paper was: "An exceptionally simple theory of everything". From: http://arxiv.org/abs/0711.0770 All fields of the standard model and gravity are unified as an E8 principal bundle connection.
