From Double-Slit to Black Hole: The Self-Consistency of Events, Entropy, and the Quantum Universe

——A Unified Framework Based on the Philosophy of Events

Abstract

The double-slit experiment reveals the fundamental dilemma of quantum observation, black hole thermodynamics exposes the deep conflict between general relativity and quantum mechanics, and the heat death hypothesis points to the ultimate destination of the arrow of time. This paper, based on a series of interconnected insights, constructs a self-consistent unified framework: (1) Spacetime is not a pre-existing background but the macroscopic emergent result of microscopic quantum events interacting; (2) Entropy is not an intrinsic property of a system but a relational property describing the probability distribution of events—an isolated elementary particle in a pure state has zero entropy; (3) A black hole is the result of a stellar collapse event, and its thermodynamic destiny is uniquely evaporation, with evaporation entropy being the sole entropy change; (4) "Heat death" does not describe the entire universe but precisely describes the irreversible process of a single black hole evaporating from its high-entropy state to a zero-entropy elementary particle; (5) The universe, as an isolated system composed of countless black hole evaporation events, has no upper bound on its total entropy, and gravitational negative heat capacity along with cyclic structures prevent global heat death. Within this framework, quantum mechanics, relativity, and thermodynamics achieve self-consistency on the basis of "event ontology."
