The Yonaguni secret

Abstract: This report provides a structural and mathematical deconstruction of the underwater formation off Yonaguni Island, Japan. By applying principles of structural mechanics (Strength of Materials) and logistics, the author identifies a consistent modular system (0.25m and 0.05m) used throughout the site. The study concludes that the monument is not a natural formation or a religious temple, but a functional maritime port terminal cast from geopolymer concrete, likely associated with the expansion of the Chinese Shang Dynasty around 1000 BC.
