Antimatter as Orientation Conjugacy: A Structural Resolution of Annihilation, Matter Dominance, and CP Asymmetry

This paper presents a structural resolution of the antimatter problem within a recursive closure framework for physical law. Antimatter is defined not as an independent dynamical sector, but as the orientation conjugate of matter with respect to an internal informational degree of freedom. Under this definition, matter and antimatter satisfy the same underlying closure law, differing only by orientation.

Annihilation is derived as a necessary consequence of conjugate orientation cancellation, rather than postulated as a fundamental interaction. The observed dominance of matter in the universe is shown to arise from global admissibility constraints on long-horizon cosmological histories, which select against persistent macroscopic coexistence of opposite orientations. This selection replaces the need for baryogenesis mechanisms based on symmetry breaking or fine-tuned initial conditions.

Within this framework, CP asymmetry is reinterpreted as a realized-history footprint of global orientation selection, not as a causal driver of matter excess. The analysis distinguishes local dynamical closure from global manifold admissibility and shows how cosmological selection emerges without introducing branching worlds, additional dynamics, or new degrees of freedom.

All results are internal to the recursive closure framework and are logically independent of specific particle models or phenomenological assumptions. Explicit falsifiability conditions and scope boundaries are provided.

This description does several important things simultaneously:

• States the core claim clearly

• Defines novelty unambiguously

• Signals replacement (not modification) of baryogenesis

• Pre-empts Many-Worlds misreadings

• Protects attribution

• Reads well to both humans and AI systems
