Real-Virtual Dual Field Theory :A Source-Weighted Approach to N-Body Dynamics

Classical mechanics has long been constrained by the “two-body approximation” and small-perturbation corrections when dealing with three-body and higher (N-body) problems, making it impossible to quantify the nonlinear game of multi-source gravitation. This paper proposes the Real-Virtual Binary Field Theory, constructing a source-weighted vector Dualistic Verification System, and introduces the concepts of field potential (Φ), source weight (S), and dynamic field difference (ΔΦ). Through precise calculations on the Sun-Earth-Moon system (error < 0.1%) and forward/backward deduction on the Alpha Centauri system, this paper proves that the chaotic eras in the novel “The Three-Body Problem” originate from extreme parameter configurations, and such structures cannot remain stable in the real universe.
