Just when you think you have some basic understanding of how things work and what holds the world together, you come across this and Whoa! - there just might be an alternate universe.
"The action for an //-dimensional supermembrane contains a chiral Wess-Zumino-Witten model coupling to the E8 super-Yang-Mills theory on the end-of-the-world 9-brane.
It is demonstrated that this boundary string theory is dictated both by gauge invariance and by kappa symmetry"
