SUMMARY
The discussion centers on the visibility of Earth's shadow at the horizon and the feasibility of calculating Earth's curvature based on this phenomenon. It is established that one cannot accurately determine the curvature solely by observing the colored band due to the Earth's non-spherical shape. Factors such as observer height and distance to the horizon are critical, along with atmospheric refraction, which affects the perceived radius of the Earth. These elements complicate any straightforward calculations regarding Earth's curvature.
