"The change in field is an electromagnetic wave, and it propagates at the speed of light. Now: since the changes in an electromagnetic field propagate at c, how is it possible that orbits in a central electrical potential remain stable? Does an electron "see" where the potential well is now, or where it was some time ago?"

I don't necessarily accept your premise that the field itself doesn't propagate.

A disturbance to a field may very well propagate at Light speed, but that's an entirely different action, in my opinion, than the field *itself* propagating.

But once the field is there, it's there. What aspect of the field needs to propagate, other than any changes to it?
