This paper proposes a unified, physical solution to two of cosmology's greatest mysteries: the matter-antimatter asymmetry (baryogenesis) and the universe's accelerated expansion (dark energy). Using the principles of the D1 Unified Field Theory, the paper presents a novel mechanism where the same process that created the excess of matter in the early universe is, in fact, the physical source of dark energy. The framework moves beyond abstract concepts by providing a single, cohesive, and testable model that links these two seemingly unrelated phenomena. This work offers a new perspective on fundamental cosmic puzzles and lays the groundwork for future experimental verification in both cosmology and particle physics.
