The Hyperbolic Prograde Encounter Model (Technical Research Paper)

This paper defines a producible alternative for the Earth-Moon origin based on the equifinality of Hadean observables. The model posits a 16M⊕ exoplanet encounter at ~55 km/s on a prograde, solar-bent trajectory at 4.5 Gya. Unlike the standard Giant Impact Hypothesis, this model demonstrates that a non-collisional "gravitational heist" satisfies the identical isotopic signatures of the Earth and Moon. Initial tidal priming beginning at 5,000,000 km catalyzed supersonic exsolution of volatiles from a 3600°F convective envelope. Upon reaching the Laplace Limit, Earth’s 3 km/s rotation triggered a tangential elliptical ejection of the silicate melt. This mechanism unifiedly accounts for lunar silicate purity, extreme desiccation via the exo-wake siphon, and the chemical signature of the Late Veneer through sub-orbital fallback.
