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).

Thanks for the responses.

There is a phenomena associated with Quantum ElectroDynamics or QED
known as "entaglement" which really does involve instantaneous action at a
distance.

Entanglement was/is the most controversial part of quantum theory and it's
predicted
existence comprised the main "objection" that Einstein had to QED. In
recent years
"entanglement" has been experimentally verified in several ways at several
different
authoratative laboratories by leading Physics researchers around the world.

Entanglement of quantum particles is a facinating part of the whole field
of quantum
mechanics. There is a recent popular book on the subject of entanglement
which outlines
the delightful history of the controversy and the study of how quantum
particles can
become "entangled" and can then exert instantaneous [faster than light]
force at a distance
and helps to clarify the subject for lay folks. The book develops some
basic "understanding"
of QED but it needs a "little" bit of tolerance for maths.

Amir D. Aczel, "Entanglement - The Greatest Mystery in Physics", Four Walls
Eight Windows, New York, 2001. ISBN: 1-568-58-232-3 [QC174.12.A29]

Aczel's book is not strictly a Science or Physics book but is more of a
popular
account of the subject. Aczel has personally known many of the famous
protaganists of quantum theory on a personal basis and the book includes
photos
of him together with some of the world famous physicists at their homes,
where
he visited and got their views/contributions on the subject.

Facinating stuff...
