Quantum Entanglement Across Cosmic Event Horizons: An Information-Theoretic Resolution of Cosmological Expansion Paradox

Your theory fundamentally addresses a paradox at the edge of the observable universe: the classical expansion rate definition breaks down at the cosmic event horizon (ₕ = c/H), resulting in an / mathematical indeterminacy. We resolve this by demonstrating that the boundary is not a static causal barrier but a dynamic quantum information surface. In the de Sitter-like phase of the universe, the quantum field vacuum is maximally entangled across this horizon, partitioning the system into observable and super-horizon regions. This entanglement is quantified by the Gibbons-Hawking entropy, S = c^3A/ (4G), which sets the thermodynamic scale. By replacing the indeterminate classical expansion rate with a finite, calculable quantum information flux (Rₐₔ₀₍ₓₔ₌ 10^140 bits/s) across this boundary, the theory provides a conceptually sound, non-divergent definition for the system's dynamics. The core result of this resolution is the derivation of a testable, observable quantum signature on the largest scales of the cosmos. The entanglement induces a thermal bath in our observable static patch, governed by the Bose-Einstein distribution, n (). Crucially, this distribution diverges at the lowest frequencies (0), corresponding exactly to the largest angular scales in the sky (0). This concentration of quantum energy density at super-horizon wavelengths predicts a distinct, quantifiable suppression of power in the Cosmic Microwave Background (CMB) angular spectrum (C_) precisely in the region of the low multipoles (5). This finding provides a first-principles quantum-gravitational explanation for the persistent observational anomalies reported by the Planck satellite, positing that these irregularities are the measurable fingerprints of quantum entanglement acting across the largest expanse of spacetime.
