  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 $\alpha$ that allows $\frac{1}{2}\alpha^{2}$ to be
interpreted as the energy of the quanta of a radiation field on superspace
whose values might still fix the coupling constants.
