Observations/Distance
Observations: Distance
We are told we live on a sphere, but all observations prove otherwise. We just see too far.
In fact, this is what woke up the FE community again. Modern consumer optics gave average people to see much further than what should be possible.
Refraction
Because we can see too far, beyond the "curve" of earth, science has refuted these observations stating it's due to refraction. Therefore what you are seeing is actually around the curve, but light is bending up magically so that it appears like the distant object is on a flat surface.
When observations of objects 20 miles away were made, refraction was their answer.
When observations of objects 100 miles away were made, refraction was their answer.
When observations of objects 200 miles away were made, again refraction was their answer.
When observations of objects 400 miles away were made, nuhuhh was their answer.
When observations of objects 700 miles away were made, silence was their answer.
Using a "Curve Calculator" ^{[1]}, we can calculate the observer's height with the distant object's height and the distance the object is, to determine how much curve is between you and the target.
Sagitta is the height of an arc or segment ^{[2]}. If we can see over the bulge or sagitta of earth's curve that would be literally miles high, the explanation of refraction becomes laughable.
