An Exceptionally Simple Theory of Everything

I saw this and thought it might be of interest to you all?


A. Garrett Lisi
(Submitted on 6 Nov 2007)
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.

New Scientist says
“GARRETT LISI is an unlikely individual to be staking a claim for a theory of everything. He has no university affiliation and spends most of the year surfing in Hawaii. In winter, he heads to the mountains near Lake Tahoe, California, to teach snowboarding. Until recently, physics was not much more than a hobby.

That hasn’t stopped some leading physicists sitting up and taking notice after Lisi made his theory public on the physics pre-print archive this week ( By analysing the most elegant and intricate pattern known to mathematics, Lisi has uncovered a relationship underlying all the universe’s particles and forces, including gravity – or so he hopes. Lee Smolin at the Perimeter Institute for Theoretical Physics (PI) in Waterloo, Ontario, Canada, describes Lisi’s work as “fabulous”. “It is one of the most compelling unification models I’ve seen in many, many years,” he says.

That’s some achievement, …”

Or just ‘google’ E8.

  1. Of course there is the possibility that the reason you have no chance is that the routes are just too hard for you! 😉
    Anyway, lets try to keep the blog on theme – i.e. Adventures and other useful stuff that we’ve done…

  2. Well Pete, there may be, after all, in this a tortuous link to our main theme in that the Grassmann referred to was, I believe, Ekhardt Grasmann, the Swiss mathematics Professor who made the first ascent of Professor’s Falls and many other of our beloved routes 😀 Small world again 😉

  3. Yeah, the very same falls. He also drove a landover up the Yamnuska screes, or tried to 😆

    He took WG, as a kid, on his first alpine climb :star:

    He died on Mt Edith Cavel, attempting a big new route 😥

    Now we are back on theme 😀
