A Unified Cognitive Phase Space Theory: From Quantum Measurement to Cosmic Acceleration

This paper proposes a self-consistent, globally unified physical framework—the Cognitive Phase Space Unified Theory. Based on the three foundational axioms of the Origin of Curiosity theory and the cognitive tensor evolution equation, this framework establishes a cognitive-quantum modified Schrödinger equation and a cognitive-gravity modified Einstein field equation through canonical coupling, constructing a complete mathematical chain connecting microscopic quantum behavior with macroscopic cosmic evolution. The core unifying conclusion is that wavefunction collapse induced by microscopic quantum measurement and the cosmic acceleration observed at macroscopic scales are two manifestations of the same information-geometric process—the monotonic decrease of cognitive entropy—at different spatiotemporal scales. The microscopic cognitive-quantum coupling constant and the macroscopic cognitive-gravity coupling constant satisfy a strict reciprocal relationship, derived from cross-scale information action and full-field dimensional self-consistency, embedding both quantum mechanics and general relativity into a unified cognitive information-geometric framework. This paper proposes three sets of cross-verifiable joint quantitative observational predictions, covering ground-based quantum measurement platforms, next-generation space-based gravitational wave detectors, and high-redshift galaxy surveys, capable of distinguishing this theory from mainstream frameworks such as the many-worlds interpretation, entropic gravity, the standard ΛCDM model, and decoherence theory. This theory naturally resolves three long-standing physical puzzles: the fine-tuning of dark energy, the anthropic coincidence of the universe, and the quantum measurement observer paradox.
