v150: Theory of Cosmic Phase-Transition Prediction — Predicting the Emergence and Collapse of the Universe via the Critical Surface Σ

This work presents v150, the completed cosmic edition of Gamma Theory, integrating the dynamical equations of v40 with the existence conditions (critical surface Σ) formulated in v70–v100. The theory predicts both the emergence and collapse of the universe by analyzing the temporal evolution of the cosmic state Γu(t) = Lu(t)·Eu(t)·Au(t) and identifying the crossing of the Ebihara Boundary. A numerical estimate under model assumptions suggests a cosmic-scale collapse approximately 2×10^11 years in the future. The paper also clarifies the hierarchical structure of phase transitions, distinguishing cosmic-scale transitions from galaxy-group and stellar-system scales. This manuscript establishes Gamma Theory as a predictive framework for the universe’s future evolution.
