Query: Huygens-Fresnel Principle in Superspace   We first roughly present a summary of the optico-mechanical analogy, which
has always been so profitable in physics. Then we put forward a
geometrodynamical formulation of gravity suitable to our intentions, both
formally and conceptually. We present difficulties in some approaches to
canonically quantize gravity which can be amended by the idea put forward in
this paper, which we introduce in the last section. It consists basically in
trying to find an intermediary between the quantization step going from the
classical superhamiltonian constraint to the Wheeler-DeWitt equation. This is
accomplished by inputting interference beyond the WKB approximation, through a
type of Huygens-Fresnel Principle (HFP) in superspace.
