Part 6/9:
- Using stacked height differences: For peaks of known height differences (e.g., 306 m between two mountains at the same distance), stacking these differences in your head shows whether they should be obscured or visible. Based on these calculations, mountains taller than the horizon due to curvature are expected to be hidden if Earth were flat.
The Evidence Within the Photo: Earth's Curvature Is Obvious
Applying these principles to the specific photo:
- The peaks, such as the one labeled Galileo (~1,182 m) and Dea (~876 m), are at roughly the same distance (189 km). Given Earth's curvature at that distance, the underlying curvature calculations predict that anything below approximately 885 meters should be hidden from view.
