The Importance of Earth's Curvature: Differentiating Earth Models
The presenter clarifies that front-to-back curvature—the curvature along the line of sight—serves as the key differentiator between the spherical Earth and the Flat Earth model. Flat Earth proponents often focus on the lack of observable curvature across the horizon's width but tend to overlook the fact that the curvature along the depth—away from the observer—is well documented through various visual and physical phenomena.
