Standard Model Fermions and K(E10)

Abstract: This talk describes an attempt to amend a scheme originallyproposed by M. Gell-Mann to identify the spin-1/2 fermions of N=8supergravity with the quarks and leptons of the Standard Model. This proposal relies in an essential way on embedding the SU(8) R symmetryinto the infinite-dimensional `maximal compact' subgroup K(E10) of the conjectured duality symmetry E10. I will also mention more recentwork exploring the possible role and significance of the eight massive gravitinos in astrophysics.
