Part 9/13:
The flat Earth defenders often argue that perspective effects could explain the observed curvature or the way horizons appear. The presenter dismisses this idea as insufficient, explaining that perspective alone cannot fundamentally alter the physical curvature of the Earth's surface. They emphasize that if perspective were solely responsible, features like the horizon should appear flat when viewed directly in perpendicular directions, which they do not.
The video also discusses how the horizon remains consistent from ground level to high altitude. Both the globe and the Flat Earth model require a horizon that appears as a continuous circle surrounding the observer, which can only be explained convincingly by a spherical Earth.
