THE SELECTION-STITCH MODEL (SSM): Space-Time Emergence via Evolutionary Nucleation in a Polycrystalline Tensor Network

Standard cosmology is currently stuck between two conflicting measurements of the universe’s expansion (the “Hubble Tension”). This paper proposes that this tension is not a measurement error, but a geometric signal of a phase transition. By modeling the vacuum as a growing 3D crystal of quantum entanglement rather than a smooth sheet, we derive a specific evolutionary timeline: from a stable 2D surface (K = 6), through a transient “gappy” fluid phase (K = 4, Inflation), to a saturated “solid” bulk (K = 12, Big Bang). We demonstrate that the modern universe is undergoing a secondary relaxation into a “Mesh Phase,” activating a geometric repair mechanism that naturally predicts an 8.3% boost in expansion. This framework offers a unified, topological explanation for Dark Energy, Cosmic Inflation, and the Hubble Tension without requiring new particles.
