Polar Impact Hypothesis v4.1: A Unified Catastrophist Framework with Narrative Prior Art — Axial Impact, Atlantis, Plate Tectonic Origin, Antarctic Formation, Human Pigmentation, Ancient Cosmological Memory, Civilization Archetypes, and Lunar Origin

The Polar Impact Hypothesis v4.1 integrates eight propositions into a unified catastrophist framework, with the addition of a narrative preface documenting the prior existence of this theoretical framework as a creative story published on the early internet and presented to Toppan Printing Co., Ltd. (Tokyo) — predating the scientific formalization by more than two decades. The story described a massive meteorite striking the heart of Atlantis, the fallen angel Lucifer flying to space to seek the primordial sea, and the sea returning to restore Earth — a complete structural encoding of PIH v4.1 in mythological form. The eight propositions are: (A) Earth's rotational axis was originally parallel to its orbital plane (0° obliquity); the impact caused the current ~23.5° tilt. (B) Borealia is the physical referent of the Atlantis legend. (C) The impact initiated plate tectonic motion from a previously static crust. (D) Antipodal hammer shock at the South Pole formed Antarctica as a compression dome. (E) Three pre-impact solar environments drove UV-adaptive human pigmentation differentiation. (F) The three major schools of ancient Chinese cosmology (蓋天説 Gai Tian, 宣夜説 Xuan Ye, 渾天説 Hun Tian) encode these environments as cultural memory. (G) Three civilization archetypes arose from environmental necessity: communal-ecological (炎天 — jungle abundance, no scarcity), harmonic-philosophical (陰陽 — balanced light, philosophy of opposition), and technological-expansionist (永夜 — existential necessity of fire, hunting, and tool development). (H) The impacting bolide ejected material that formed the Moon. Eight falsifiable predictions are offered. V=N/D: one event, eight domains of explanatory coherence.
