Beyond Fusion: A Hypothetical Non-Fusional Reactor Model for Stellar Energy Generation

This paper presents a speculative theoretical framework for stellar energy production without nuclear fusion, proposing an alternative "reactor-like" mechanism to sustain a Sun-like star’s luminosity of 3.826 × 10^26 W and hydrostatic equilibrium over billions of years. Exotic processes, including enhanced gravitational energy conversion, exotic matter annihilation or decay, and quantum vacuum energy extraction, are explored through conceptual analysis, mathematical modeling, and observational implications like altered neutrino emissions and density profiles. Grounded in established physics where possible, the models rely on hypothetical extensions beyond the Standard Model (BSM). Data from the Jiangmen Underground Neutrino Observatory (JUNO), starting August 26, 2025, confirming ^7Be, pep, and CNO neutrino fluxes consistent with the Standard Solar Model (SSM), alongside Deep Underground Neutrino Experiment (DUNE) enhancements, empirically negate non-fusional mechanisms. This thought experiment challenges stellar astrophysics, highlighting BSM possibilities while acknowledging its lack of observational support, violations of conservation laws, causality and sustainability issues, inconsistencies with the Hertzsprung-Russell diagram’s fusion-driven main sequence, and self-refutation due to reliance on contradictory data. It exemplifies the scientific method’s rigor in testing speculative hypotheses.
