This paper proposes a structural explanation for Venus’s retrograde rotation based on the vortex model of Interference-Based Generative Theory. Rather than relying on the conventional giant impact hypothesis, this model derives the retrograde rotation as a structural necessity from three converging conditions: Venus’s formation position between the solar vortex and the pre-established Earth vortex; Mercury’s orbital pulsation creating periodic modulation of the solar prograde torque; and a 5:1 resonance between the Venus-Earth synodic period and Venus’s solar day (583.93 ÷ 116.75 = 5.0015). The inverse-square law, spacetime curvature, and gravitational phenomena are reinterpreted as consequences of vortex structure— absorption and leakage differentials maintaining persistent rotational motion.
