Cosmology and the Quantum Gravitational Origin of Dark Components: Dynamic Zeros and Spacetime Emergence

Cosmic dark components (dark energy and dark matter), accounting for ~95% of the universe’s total energy budget, remain a key puzzle in modern cosmology, with their origin and the "cosmic coincidence problem" (why their densities are comparable today) unresolved. This preprint unifies the quantum gravitational origin of dark components via a spacetime quantization framework driven by dynamic zeros, integrating graviton Bose-Einstein Condensate (BEC) dynamics and tensor network spacetime evolution. We show that the phase transition of graviton BEC during cosmic inflation shapes the initial distribution of dark components, while the discrete symmetry of dynamic zeros derives their evolution equations—naturally resolving the coincidence problem. Additionally, we propose a unitary solution to the black hole information paradox: information absorbed by black holes is encoded in the high-dimensional geometry of the event horizon and retrieved via dynamic zero-mediated quantum entanglement. The study’s predictions, including primordial gravitational wave tensor spectra and mass constraints on ultralight bosons in graviton BEC, are compatible with current cosmological observations and offer testable targets for future high-energy astrophysical experiments.
