He insists that my usage of the word field is not standard in physics and that medium should be used. As if quantum field, electromagnetic field, gravitational field, Maxwell's field equations aren't standard in physics.
Show us examples from actual textbooks where they say "light travels through an electromagnetic field" or "sound moves through a density field".

Despite the fact that I used your own analogies, you never answered my questions:

How about a stick of dynamite and a nuclear bomb, both a high altitude? The shockwaves are both spherical.

Light is a wave, it is not an analogy.
An electromagnetic wave satisfies a (mathematical) wave equation.

Physicists use analogies to make the rigorous treatment more understandable, not to substitute it.

Style over substance.
Instead of complaining about my style, you should address the substance of my points.

Please show us exactly what are these "obvious" deficiencies and what is wrong with them.

It is fairly clear that you are confusing isotropy and homogeneity.
The fact that you prefer complicated waves and avoid my examples (see my questions above), is a sign that you cannot make your idea work as you would like.

If you all think that snippyness is ok but that pointing out errors in sombody's posts is an attack then you all have some insoluable problems.
Why don't you stop complaining about my tone, and show us exactly why my points don't stand.

It's time to put your money where your mouth is.
