A gravitational field is observed as both a particle and a wave. The bubble/film collapse at a double slit or concentric slit configuration generates bursts of particles/droplets. The droplets beyond the "invisible" slits can be regarded as dark matter, having the same fluid/gravitational properties of the original particle/wave.
