Cosmic Data Rendering: The Impact of Quantum Entanglement at the Black Hole Boundary on the Expansion of De Sitter Space

While modern holographic cosmology has been successfully demonstrated in Anti-de Sitter (AdS) space, it faces a fundamental challenge in the realistic De Sitter (dS) space—which possesses a positive cosmological constant and exhibits accelerated expansion—due to the inability to specify a global screen upon which information can be projected. This study proposes redefining the holographic screen of the expanding universe not at the unreachable boundary of cosmic infinity, but at the "local event horizons" of black holes distributed throughout the universe like a network. To demonstrate this, we analyze vacuum quantum fluctuations (Hawking radiation) occurring near the event horizon by combining them with the ER=EPR hypothesis. When one member of an entangled particle pair falls into the black hole, increasing the informational entropy (2D data) of the horizon, the partner particle emitted into the external cosmic space—while maintaining its entanglement—is fundamentally compelled to expand the metric of the physical field it occupies in order to render this increased backend data. Consequently, this paper argues that the accelerated expansion of the universe is not a blind repulsive phenomenon caused by unknown dark energy, but rather an information-theoretic and thermodynamic evolutionary process in which the frontend space (the universe) expands its own rendering capacity in synchronization with the increase in quantum information processed by the black hole network.
