In previous work it was argued why it is practically inevitable to assume the existence of an S-matrix that describes particle absorption and production by a black hole, and the relationship between this S-matrix and string theory was derived. The physical interpretation of the corresponding mathematical expressions however is quite different from string theory. We have an algebra of operators now defined on a two-dimensional Euclidean "world sheet". The algebra simplifies if one restricts it to the self dual projection of the fundamental surface elements Wμν. Our two dimensional functional integrals correspond to a rather unusual field theory. The long distance structure of this theory follows directly from the long distance structure of the standard model at the GeV scale. We emphasize the rather delicate physical interpretation of this approach.
