This paper proposes a novel quantum gravityframework based on the transient annihilation and regeneration of positron pairs, aiming to unify quantum mechanics and generalrelativity. The model integrates insights from black hole thermodynamics by addressing the information paradox through Hawking radiation dynamics and incorporates phase transitionsinto the theoretical framework to explain the evolution of dark energy. The proposed graviton model is further supported by advancements in gravitational wave detection technology,Additionally, the paper explores the application of quantum sensing technologies, such as superconducting quantum interference devices (SQUIDs), for dark matter detection, leveraging ultra-cold atom interferometers to study cosmicmicrowave background radiation fluctuations. The model's predictions are supported by a rigorous theoretical framework and experimental validation strategics, including quantitativeBayesian factor analysis and feature spectral matching tests. Future research directions include the development of numericalrelativistic codes for dynamic spacetime grids, the establishment of an inter-institutional dark energy time landscape observatory, and tabletop experiments using superconducting quantuminterference instruments to test the theory's predictions in Earth-based settings.
