Abstract
Unification scale threshold corrections in minimal SU(5) supergravity grand unification are discussed. A probe of the underlying theory is o utlined, where low energy measurements can in principle measure the ef fects of Planck scale (1/M(P1)) terms. A bound relating the strong cou pling constant to the mass scales associated with proton decay and sup ersymmetry is derived including uncertainties associated with the high energy scale.
