Two slit experiment - quantum particle trajectories revealed in Bohmian mechanics

Below is a computer generated model of behaviour that cannot observed or directly detected by any means of objects.  It is a theoretical representation of how quantum objects should behave if they were both waves and particles while in motion.  And so that what causes thipatern of behaviour can be said to be an extended wave property of each individual object.  The diagram repesents trajectories of particles in a double slit experiment that has been performed on many types of object on the quantum scale, and up to size of quite large molecules.  http://plato.stanford.edu/entries/qm-bohm/#2s
