>strongest nudges, more distant ones giving smaller nudges. This is one of the phenomena I've attempted to model & in Ampère’s view, the “wave” is simply the cascading pattern of those interactions, which we interpret as having electric and magnetic components, but which are in fact two aspects of the same underlying force.
This "cascading pattern" literally is just a field though lol. The Maxwell system is symmetric hyperbolic and the wavefront set of [math]F[/math] propagates along null bicharacteristics. Singular support lives on the light cone, i.e. there is no spacelike transport. Your cascading nearest‑neighbor pushes is a verbose re‑description of a local hyperbolic PDE with retarded Green’s function.
