Dynamical Origin of the Baryon-Antibaryon Asymmetry of the Universe: Interpretation Based on Continuous Ejection from the Central White Hole and Primordial Field Phase Transition

Baryon-antibaryon asymmetry is an unsolved core puzzle in modern particle physics and cosmology. According to observational results from the Planck satellite, the baryon-to-photon ratio is expressed as $\eta=\frac{n_\mathrm{b}-\bar{n}_\mathrm{b}}{n_\gamma}\approx6.1\times10^{-10}$, which reveals the net surplus of baryonic matter over antimatter. Extensive mainstream studies have been constructed around CP violation and baryogenesis theories, yet these frameworks fail to precisely fit observational data and naturally fulfill all three Sakharov criteria simultaneously. Breaking the conventional paradigm of microscopic parameter fine-tuning, this paper establishes a dynamical deduction system from the macroscopic perspective of primordial field phase transition based on the cosmic evolution framework of central white hole and void field. In the extreme spacetime of primordial cosmos, chaotic energy produces primordial baryons and antibaryons strictly at a 1:1 ratio. The subsequent rapid cosmic expansion induces irreversible global vacuum
