Black Holes as Ontological Defragmenters: Resolving the Information Paradox via Erasure

The Black Hole Information Paradox arises from the conflict between the unitary evolution of quantum mechanics (which forbids information loss) and the thermal nature of Hawking radiation (which implies it). This paper proposes a resolution by abandoning the assumption of unitarity in favor of a Finite-Capacity Computational Ontology. We argue that black holes function not as anomalies, but as Ontological Defragmenters: mechanisms necessary to prevent the informational saturation of the universe. In a system where time requires the continuous erasure of past states (The Null Pointer Paradigm), black holes serve as high-density erasure zones, converting "used" quantum information into "clean" vacuum energy (Hawking Radiation). Furthermore, we present an Order-of-Magnitude Estimate linking the thermodynamic cost of this universal erasure process to the observed value of the Cosmological Constant (Λ). We demonstrate that the cumulative heat generated by the erasure of information over the age of the universe approximates the energy density of Dark Energy, suggesting that cosmic expansion is the thermodynamic exhaust of temporal processing.
