I guess for now I will accept that a radio wave is a force field (or
energy field, if you like), and leave it at that (still seems to imply
action-at-a-distance). When I was in school, if this question were
asked, the professor would right down Maxwell's Equations on the
blackboard and state that they explain everything. I suppose that's
about as good as anything.
Thanks for the responses.
