According to Wikipedia, "An Exceptionally Simple Theory of Everything is a physics paper submitted to the arXiv library on Nov. 6, 2007 by Antony Garrett Lisi. His theory claims to unify all fields of the Standard Model with gravity using a 248-point lattice of E8 geometry. It has not been peer-reviewed nor published in a scientific journal, but it has drawn a wide range of professional reaction and stirred public interest in the topic and its author."

Accoridng to Dr. Lisi himself, "Yes, the title is a little much. Technically, a Grand Unified Theory in physics is a theory unifying the electromagnetic, weak, and strong forces as parts of a single Lie group. And if gravity is described in a unified framework like this, it's called a Theory of Everything, because that's all the forces we know of. The paper describes a new theory of how to do this, with all these forces (and all matter) as parts of the largest simple exceptional Lie group, E8 (which is very beautiful). So the title is technically accurate, but I probably should have made it less sensational. Especially since the paper does not include the details of a complete quantum description, which is really necessary for it to qualify as a successful ToE. (I'm counting on combining my work with that of the Loop Quantum Gravity community to build a full quantum E8 theory of everything.)"

Fortunately for us, E8 seems to be a subset of Zome geometry (or vice versa.) In Two Results Concerning the Zome Model of the 600-Cell, Dr. David Richter says that the Zome System is a great tool for studying the associated geometries of the Coxeter group E8. He echos Dr. Lisi's wonder at the beauty of 8-dimensional space, and offers tips for building a 3-dimensional shadow of Gosset's Polytope, which lives in E8. David also coauthored a related paper with Dr. Scott Vorthmann, Green Quaternions, Tenacious Symmetry, and Octahedral Zome. Scott muses on Coxeter groups, including E8, and the Gosset Polytope at his web site, vorthmann.org. Of course, you can also find his wonderful vZome software there!

Garrett may even develop an "Exceptionally Simple Theory of Everything Zometool Kit" with us, and who knows? Maybe this stuff really will be exceptionally simple one of these days... we certainly hope so!
