A Novel Hypothesis of Cosmic Evolution: Resolving the Superluminal Paradox, Reconstructing Black Hole Interior Dynamics, and Quantifying the Cyclic Timescale of the Universe

This paper proposes a novel cosmic evolution hypothesis that identifies the Oppenheimer limit as the minimum quantum threshold for the transition from classical general relativity to quantum gravity. By strictly distinguishing matter motion from spacetime background flow, the hypothesis resolves the long-standing superluminal infinite-mass paradox and establishes a physically valid finite-mass superluminal mechanism. It reconstructs the complete singularity-free evolutionary chain inside black holes, including spacetime folding, quantum compression, and cosmic rebound. Based on an original cosmic critical coefficient and dynamical equation, the full cyclic lifetime of the universe is quantitatively calculated to be 50–60 billion years. This work provides a new self-consistent paradigm for unifying gravity and quantum mechanics and solving key problems in cyclic cosmology.
