According to quantum realism, quantum processing put on the grid immediately spreads out in all directions, like ripples on a pool but in three dimensions. If a photon is a Planck process shared among the nodes of its wavelength, they in turn will also pass it on in every direction at one node per cycle, i.e. the speed of light. Huygen’s Principle, that light is a wave spreading with each point a new wave source, then follows from the nature of the quantum network. It follows that a light “ray” isn’t a particle traveling a linear path but a wave spreading in all directions at the same time, and it is this wave that goes through both Young’s slits at once.

Why then does light travel in a forward direction rather than just spreading out equally? It is as Huygen explained, because the wave has a “front” and a “back”. In our terms, the nodes at the wavelength front started after those at the back, so they are just starting to run the Planck process when those at the back are just finishing it. If the network passes on the processing of each node in all directions, what spreads backwards is cancelled but what goes forwards isn’t. The wave front moves forward due to the processing sequence of the photon wavelength, just as happens for a water wave.

Gauss noted that when a pebble drops in a pool, the initial energy spreads out in ripples of decreasing strength such that the energy flux per ripple is constant, but for friction. As shown in Figure 3.12, each ripple is the same energy spread out over a larger circle. This principle applied to the three-dimensional “ripple” of light is that the processing flux is constant and there is no friction. That a quantum “flux” spreading on a sphere surface reduces power as an inverse square of distance gives the inverse square laws of electricity, magnetism and gravity. It also predicts that processing values cancel at the node as fields do at a point and that processing is passed on every cycle at the speed of light, as fields propagate.The next chapter attributes all the fields of physics to one quantum field.
