Revised version corrects angular momentum and isotope values for the Earth-Moon system and related celestial bodies, suggesting new implications.
Version 6 (July 2026). This revision corrects several numerical errors in Version 5 (June 2026), including the total angular momentum (off by ~10^7), the Earth–Moon Δ¹⁷O value (corrected to ±0.016‰ per Wiechert et al. 2001), the solar escape speed at 2.0 au (corrected to 29.8 km/s), relative velocity statistics, and the fragmentation formula. Additional changes include: added Roche-limit staging for tidal disruption (§2.2); clarified massless test particles (§3.1); added upper-bound caveat and Theia uniqueness argument via angular momentum scaling (§4.2–4.3); tightened isotope argument to "NC scatter ≫ Earth–Moon difference" (§5.1); expanded limitations to include tidal disruption SPH and satellite capture timescale (§9); added returned-sample references (Dai et al. 2026, Jin et al. 2024, Li et al. 2026, Ma et al. 2026) and Prediction P7. Readers who cited Version 1 should check §3.3, §4.2, and §5.1 for corrected values.
