I'll go on with that thought: It is a big if, but IF you think particles have both a wave nature, and a particle nature, which I think most people here do, then we can say some things about wave-particles in general: 1) Their wave presence is not likely to be just one wave moving through the medium of space, but they would be standing wave patterns of intersecting waves. Those intersecting waves overlap within the "particle space", and each intersection/overlap causes a momentary and fleeting high density spot to form there because the wave energy of each intersecting wave adds its energy to the space where the intersection/overlap occurs. 2) Since these intersections/overlaps would then typify the action that is taking place within the particle space, when you take the entire particle space into consideration, it is continually filled with an ever-changing pattern of high density spots, as the waves flow in directionally, and flow out essentially spherically from the particle "boundary". It is the continual presence of an internal structure of high density spots that establishes the momentary location of the particle. 3) Particle motion is caused by a directional imbalance of the inflowing wave energy component of the particle's complex standing wave pattern. Inflowing wave energy is coming from all directions, but the density of the inflowing wave energy is not equal in all directions. The particle moves in the direction of the net highest source of wave energy inflow. When looking at the distribution of high density spots within the particle space, they would be skewed toward the highest inflowing wave energy density direction.
