The Ontomatter Hypothesis: A Novel Framework forGravitational Mediation and Matter-AntimatterAsymmetry

This paper introduces the Ontomatter Hypothesis, a theoretical framework proposing a novel form of fundamental substance that mediates gravitational interactions and potentially explains the observed matter-antimatter asymmetry. We explore its compatibility with General Relativity, its implications for the Einstein Equivalence Principle, and its integration within quantum field theoretical contexts. The hypothesis offers a reinterpretation of the space-time curvature, a mechanism for baryogenesis, and outlines experimental paths for validation.
