Query: Singular Structure in 4D Simplicial Gravity   We show that the phase transition previously observed in dynamical
triangulation models of quantum gravity can be understood as being due to the
creation of a singular link. The transition between singular and non-singular
geometries as the gravitational coupling is varied appears to be first order.
