We study the dynamics of multiwormhole configurations within the framework of the Euclidean Polyakov approach to string theory, incorporating a modification to the Hamiltonian which leads to a Planckian probability measure for the Coleman parameters $��$ that allows $\frac{1}{2}��^{2}$ to be interpreted as the energy of the quanta of a radiation field on superspace whose values might still fix the coupling constants.
