Flat Earth Sun Simulator v303 · 3D + ANALYSIS

Perspective compresses objects toward a vanishing point on the horizon line, and that line is at eye level, dead ahead. A light 3,000 miles up can approach that line but its geometry never carries it below the flat plane you stand on — there is no angle at which a lamp above the floor sinks beneath the floor. Perspective would also shrink the sun to a vanishing dot as it receded, yet the setting sun keeps its full disk right down to the horizon and reddens rather than shrinking. The amber path above is the honest result: under the flat model the sun remains geometrically above the horizon throughout the entire 24-hour cycle, dimming but never setting.
