OPTICS? OR EARTH CURVE?

OPTICS? OR EARTH CURVE?
Have you ever seen Earth curve and distance dependent angular resolution in the same frame at the same time ? What if they are the same thing?

We all know there is an apparent drop proportionate to distance. The mainstream position is that this bottom up obstruction is caused by the geometric physical earth curve. The counter position has always been that his effect is optical in nature, and not due to physical earth curve.

What it comes down to is this: The loss of information at our horizon is either optical, or physical.
If it's physical, things will simply disappear over the horizon.
If it's optical, things will disappear by angular resolution limit of the observer.
We are trying to use math to distinguish which is true.

Our argument:
If earth curve is actually physical, why can I use the values of optical limits of perception to derive the supposed radius of earth to the 8th decimal place?

The loss of information at our horizon is either optical, or physical (or both).

Well lets look at the values we chose to use, and why we chose them.

These are the values we used.
Wavelength = 666 nm
Diameter = 2.16mm

Why did we choose these values?
Well, because they represent the most commonly experienced circumstances of course.
The diameter of the Pupil (typically) ranges from 2-4 nm to 4-8nm, and it narrows the further out you look.

Wavelengths of light vary on a scale, with atmospheric scattering scaling low to high with refraction scaling high to low with the wavelength.
We chose 2.16mm because the furthest field would be most dilated.
We chose orange/red because they are LEAST susceptible to refraction.

Since the angular resolution limit and the expected rate of drop due to distance are two factors that will ALWAYS yield the radius, how can we now conclude that this value is NOT based on optics?

It seems there is now a huge disparity in the amount of evidence for physical curvature VS optical curvature....

I wonder if anyone will ever find any?

I wonder if some glober will present some math to counter the derived the radius with a higher degree of accuracy than 8 decimal places?

I wonder which side is right?
