I don't know how much you know about quantum physics, but is it possible that like the water droplets, this concept is the way some particles can pop in and out of existence, through stronger vibrations in the quantum foam? These particles can simply be concentrated vibrations revealing points of detection until the vibration dissipates back into the fundamental plain of our universe, like the droplet with the water that dissapears back into the surface of the pool. That could be why these partials cannot appear between any two parallel plates because it interfers with any concentrated vibrations. Just a thought...
