...............Logical Deduction
If one presumes that light can only traverse a certain amount of space -time substrate in a certain amount of time , then logically , gravitational compression of S.T. would result in longer traverse times for a given distance .  The alternative concept is that of ST as a virtual river .  This would explain light being unable to overcome a "river" moving "faster" than it can .  Alright , time will tell ! P.M.

I think that SR~GR says that light always travels at the same speed in its own frame (ie c kmps) but that in a gravity field the light's frame suffers time dilation which makes that light appear to be slower to observers who are located in a weaker gravity field, plus the light's frame suffers length contraction in a radial direction (two radial directions)(in & out) which to the outside observer further slows the light in thems two radial directions -- hencely the slowing is apparent & relative (at least thats what i think Einsteinians think).

In my aetheric universe the speed of light c is variable, c is only ever fully achieved at a location well away from any mass or other photons or other radiation (ie c is never fully achieved). This is because photons are slowed by photaeno-drag, the photaenos emanating from the main central helical body of a photon are slowed when they fight with other photaenos, all fighting for the use of the aether (a photaeno being a vibration or spin or something of  the aether)(& aether does not have an infinite capability in that regard). The slowing or drag of the photaeno feeds back to the main body thusly slowing the main body too.
Or if u like u can simply say that the longitudinal progress of the main helical body is likewize slowed for the same reasons as the outwards progress of the photaenos are slowed (no photaeno feedback needed)(simpler really). I suppose that we can give this drag its own name, eg photon drag.

Photaeno drag might be equal to photon drag, or not (i havent thort this throo).
Photaeno drag affects the speed of radiation (eg em fields)(em fields might travel at c)(or i should say at c', ie less than c).
Photon drag affects the speed of light c, c is usually reduced to say c' (which might not be equal to the c' mentioned for the speed of an em field).
The reduced speed c' probly doesnt depend on direction (but praps it does).

Conrad Ranzan's DSSU theory says that the infinite universe is made up of large cosmic cells, each cell having areas of concentrations of stars etc, & with areas of voids -- however every inch is filled with aether of constant density but varying speed (aetherwind).

Not sure what aether wind is , but I'd be willing to bet it's less dense in intergalactic voids .

Aetherwind is what an MMX detects (fringeshift) & measures (kmps)(if calibration is accurate)(ie kmps/fringeshift).
On Earth the aetherwind is about 500 kmps, blowing south to north about 20 deg off Earth's spin-axis, RA 4:30.
In the best aether theories that i see the aether has a constant density, but a varying speed.
Conrad Ranzan mentions cosmic voids & also zones of concentration of galaxies.

When you say "gravitational field" you realize nobody knows what Gravity is right. So what is that field then?

I daresay that there are lots of theories re what is gravity. And all of these will be compatible with having some sort of gravity field.
For aetherists a GF can be defined in one or two ways.  A simple way is to have the field describe the force at any location &/or time. Or one could get closer to the cause, which is primarily the acceleration of the aether flow flowing into matter where it is annihilated -- in which case the GF could be defined in terms of that-there aether acceleration.

For Einsteinians there is no force, gravity is due to a bending of spacetime -- in which case the GF might be a description of the way  that spacetime bending varies with location &/or time.

Or on the other hand one doesnt have to know the micro cause of gravity -- but one can nonetheless well describe the measured force field & how it varies with location &/or time.

In any case no matter how much u know or think u know there will always be an underlaying mystery -- meaning that we will never fully understand anything -- every answer raises an even more difficult mystery.

The field is a measure of the attraction a test mass (1kg) feels towards another mass. This can be measured as a force or as an acceleration eg g.
Relativity doesn’t say there is no force, just looks on it as a fictitious force (ie frame dependant, as with centrifugal force). The force is the one you measure every time you step on the bathroom scales and is very real.
