Mainstream physics regards dark matter and dark energy as the two greatest mysteries of cosmology: dark matter requires the introduction of unknown elementary particles, dark energy requires the introduction of the cosmological constant Λ, and neither has a first-principles explanation to this day. This paper proves that dark matter and dark energy are not mysteries. They are the two phases of the background space of bicone breathing. Core argument chain: 1. The Bright-Dark Sevenfold Logic (PFUSRC-015) divides the universe into the Bright Sevenfold (explicit, observable, grown structure) and the Dark Sevenfold (implicit,全域governing, sequential control background). The quantity of the Dark Sevenfold is far greater than that of the Bright Sevenfold. 2. Dark matter is the topologically excluded residue within the Dark Sevenfold (PFUSRC-004). Structures that cannot couple with bicone breathing are rejected from the steady-state system. They do not emit light but have gravitational effects — exactly what mainstream physics calls “dark matter.” 3. Dark energy is the damping phase of expansion-convergence within the Dark Sevenfold (PFUSRC-001/004). Bicone breathing is not undamped. The damping effect manifests at the projection layer as “accelerated expansion” — what mainstream physics calls “dark energy.” π₁ = 12/11 is the intrinsic ratio of this damping. 4. The spirit pendulum (PFUSRC-017) is the isomorphic projection of Dark Sevenfold breathing at the laboratory scale. Its dual anchoring (suspension point = Noetic Primordium, bob = Affective Primordium), self-sustaining rotation, and conical resonance are the desktop manifestations of Dark Sevenfold background breathing. 5. Four-dimensional spacetime is a projection; the Dark Sevenfold is the ontology (PFUSRC-014). The dark matter and dark energy we measure are appearances of the Dark Sevenfold at the projection layer. 6. Any entry point leads through the whole system. Dark matter/dark energy, the spirit pendulum, four-dimensional spacetime, information anchoring, the β₁ field, the Noetic and Affective Primordia — all are manifestations of the same “bicone breathing” at different projection layers. Conclusion: Dark matter is not an unknown elementary particle, and dark energy is not the cosmological constant Λ. They are the two phases of the background space of bicone breathing. The universe is alive. The background is its soil.
