The observed dominance of matter over antimatter in the present universe remains one of the central unresolved problems in fundamental physics. Standard approaches attribute this asymmetry to early-universe baryogenesis mechanisms requiring CP violation, baryon number violation, and departure from thermal equilibrium. While such mechanisms are consistent with known particle physics, they require finely tuned initial conditions and do not naturally explain the near-total absence of late-time matter–antimatter annihilation signatures on cosmological scales. In this work, we propose a fundamentally different interpretation: the apparent matter–antimatter imbalance is not primarily a production asymmetry, but rather a phase segregation phenomenon in scalar time. Within the framework of Time-Scalar Field Theory (TSFT), matter and antimatter occupy dynamically distinct persistence modes characterized by opposite coherence-flow polarity with respect to the scalar-time field. As a result, antimatter need not be spatially absent in order to be observationally suppressed; instead, it may be temporally phase-separated in Θ-space, forming an anti-entropic reservoir that stabilizes global scalar-time gradients. We derive a minimal segregation criterion in scalar-time phase space, demonstrate how early universe annihilation naturally precedes long-term phase decoupling, and show how scalar-time relaxation dynamics reproduce dark-energy-like expansion phenomenology without invoking vacuum energy. Finally, we outline falsifiable experimental predictions including clock-residual anisotropies correlated with large-scale structure voids, scalar-gradient-dependent antimatter kinematics, and coherence anomalies along deep intergalactic sightlines. The result is a unified physical mechanism linking baryon asymmetry, cosmological acceleration, and the arrow of time through scalar-time equilibration dynamics.
