A Conceptual Framework for Dark Matter and Dark Energy as Manifestations of Quantum Gravitational States

We propose a conceptual framework in which dark matter (DM) and dark energy (DE) emerge as different manifestations of the quantum gravitational field. Using the density matrix formalism for gravity, we distinguish: 1. Locally decohered gravitational states (ρdec): classical on local scales, potentially corresponding to DM. 2. Globally coherent gravitational states (ρcoh): quantum coherent on cosmological scales, potentially corresponding to DE. This framework does not modify existing formalism, but offers an interpretational reading. It establishes the conceptual priority of the idea and allows for subsequent expansions or formal developments.
