The Causal Role of Information: Quantum Entanglement as the Driving Force of Cosmic Evolution

This manuscript presents a fundamental physical theory that resolves the profound contradiction between the irreversible thermodynamic entropy and the reversible principle of unitarity in quantum mechanics. We postulate that the observed increase in entropy and the dispersion of energy are not a primary cause but rather the inevitable consequence of a deeper, causal, and unidirectional process: Information Condensation. The physical mechanism of this condensation lies in Quantum Entanglement, which is understood as a universal, emergent network of correlations. We derive a fundamental relationship that directly couples the increase in thermodynamic entropy (ΔSth) with the increase in entanglement entropy (ΔSent), which mathematically formalizes the causal link between energetic dispersion and informational condensation. This theory interprets the Big Bang as a state of minimal informational complexity and "Heat Death" as the culmination of maximal informational density. It further argues that the indestructibility of information causally necessitates the preservation of matter and energy as its essential physical carriers, thereby providing a new explanation for the fundamental conservation laws.
