Part 15/15:
Science relies on repeatable, measurable phenomena, and numerous experiments—ranging from high-altitude photography to long-distance observations—corroborate Earth's curvature. Claims to the contrary often ignore the limitations of perspective, atmospheric conditions, or surface irregularities that have been thoroughly studied and understood within the framework of globally accepted physics.
In essence, the bottom-up horizon disappearance, supported by a multitude of evidence, remains a robust indicator of Earth's curvature—not an artifact of mirages, wave interference, or perspective distortion alone.
