Its worth pointing out though that if light were to not
decrease in observed frequency the farther from source in a non
expanding universe it would then be travelling at infinite speeds

This is not correct.
What you say here is: 'Light frequency drops over distance.'
And you are also implying that that has to do with the speed at
which light travels.

Whatever picture you may have of light, if we take a pond, throw a
stone in it, we see a circular wave pattern emerging from where the
stone hit the water.
The wavelength (frequency) will not change.
Ducks at fixed positions from the source (1 meter, 2 meters, etc) will
bump up and down on those waves in the *same* frequency, and the pool
was not expanding.

(Somebody else give the particle 'photon' explanation, this was the 'wave'
one).

So I think you have some misunderstanding of what EM waves are.
Possibly , but I dont think you`re right in saying an em
wave propogates through space like a water wave. To start
with the water wave is one where the molecules go up and
down and back and forth I believe,... but with EM waves I
thought its just flux, intensity, frequency, and spin. No
movement like water. Isnt this the case? And if so then
how does that explain momentum in EM waves?
For a moment yesterday it thought you wanted to state that *time* changed,
but this does not seem to be the case.

You can see from above model that as a duck swims away from where the stone
hit, the faster it goes the less bumps (wave maxima) it will pass per unit of
time, it sees a lower 'frequency', Doppler effect.

If the duck was fast enough, then it could even keep up with the wave and see
DC (a fixed elevation level, it could always ride a 'high' (wave top) or 'low'
(wave bottom, or anywhere in between.).
Yes but as I say above were not talking now about ducks on water waves.
My impression is that light does not propogate in the same mechanical
way as the water waves?
