Perhaps we can agree that they could at least share a common media

Hi Jim,

Certainly, at a minimum.

A load
is required to reveal the cancellation.

A load - like a transducer of some sort. That would indeed be
required in order to convert the effect to a form that we can more
readily observe.

Every mapping of an antenna's radiation lobe characteristics presumes
this. We call them receivers.

No load, and any issue of
cancelling fields is strictly limited to what goes on between the
ears.

I hope you're not suggesting that if we cannot observe the
interference effect, it does not occur.

Contrary to the implication of Tom's tree falling unheard in the
forest, no I am not suggesting that. If one plants a load at a
distance and ignores it; then, yes, interference occurs. Remove the
load, and you remove interference.

1. Interference follows the load.

2. A load will also perturb the fields by the degree it couples to
the fields, and create a new interference solution.

There is good reason to
believe that just the opposite is true, Richard. It's a real paradox.

Not sure what the paradox is, but I trust you will elaborate if
necessary.
