http://arxiv.org/abs/1002.1497 :tongue: :rofl: :rofl: I just mentioned RCHO in other thread, and an article appears. Very predictive, I am :-DDD I haven't read it. I will not, most probably, in a few days. But I feel it could be place for a thread on the topic of relationship between unification and normed, division, algebras. You may know, or perhaps not, that it is actually a *mainstream* topic. Evans did a proof of the relationship between supersymmetry and this kind of algebras. Of course it is also a "lost cause". But perhaps it could be regained. Also the vector-"diagonal" generalisation of Evans argument builds the full BraneScan, which can be also told to be mainstream. I told of the brane scan here, https://www.physicsforums.com/showthread.php?t=181194 BTW, the guy is at Perimeter, with Sorkin.
