Energy is the variable conjugate to time, so the Hamiltonian is the operator that evolves solutions in time. That's where the potentiality comes in. For example Vic considered a boundary condition in which the size of universe was imaginary in which case the evolution is tunneling into a real value. Lawrence Krauss speculates that the CC is negative pressure and so an infinitesimal fluctuation of space from Nothing would expand and do work on empty space as it expanded thus producing matter and radiation with a net zero Newtonian energy (i.e. counting only matter and gravity). So Krauss argues that the laws of physics provide this potentiallity and the potential for something-from-nothing must be allowed since if you adopt the contrary you will conclude from mere semantics that the universe could not have begun.
