I'm going to digress a bit from the main thread, but I was wondering if
the gravitational effect of the atoms at the edge of the slit have a
measurable influence on the photons or neutrons passing through, i.e.
if it were possible to make the slit in some hypothetical massless yet
opaque material would the fringe pattern you see be measurably different
from the one you get with a slit in real matter.
