The Polar Impact Hypothesis v3.0 integrates six propositions into a unified catastrophist framework explaining Earth's geological, biological, and cultural configuration as consequences of a single event: a massive bolide impact on a proto-Arctic supercontinent (Borealia). The six propositions are: (A) Earth's rotational axis was originally parallel to its orbital plane (0° obliquity), and the impact tilted it to the current ~23.5°; (B) Borealia is the physical referent of the Atlantis legend — a supercontinent that "sank into the sea" when the impact created the Arctic Ocean basin; (C) the impact initiated plate tectonic motion from a previously static crust; (D) antipodal hammer shock at the geographic South Pole formed the Antarctic continent as a compression dome; (E) the three distinct solar environments of the pre-impact 0°-obliquity Earth — polar炎天 (North), equatorial horizontal sun (Equator), and polar night (South) — drove the UV-adaptive differentiation of human skin pigmentation; and (F) the three major schools of ancient Chinese cosmology (蓋天説 Gai Tian, 宣夜説 Xuan Ye, 渾天説 Hun Tian) independently encode these three solar environments as preserved cultural memory of the pre-impact Earth. Eight falsifiable predictions are offered. V=N/D: one impact event generates explanatory coherence across six academic disciplines.
