Unified Meta-Spacetime Theory (UMST-X²): A Meta-Informational Framework for the Emergence of Geometry, Causality, and Physical Laws

This work presents the Unified Meta-Spacetime Theory (UMST-X²), a next-generation theoretical framework in which spacetime, causality, and cosmic evolution emerge from two fundamental meta-geometric fields: the Quantum Information Field and the Meta-Causal Potential .The theory constructs a fully closed mathematical system describing how curvature, causal structure, and temporal directionality emerge from informational and meta-causal dynamics. UMST-X² reproduces the key successes of General Relativity while providing new explanations for several open problems in modern cosmology, including dark-matter-like gravitational behavior, dark-energy-like cosmic acceleration, CMB low-ℓ anomalies, and the Hubble tension.The framework naturally predicts direction-dependent expansion, anisotropic large-scale structure formation, and informational curvature lensing. In addition, the work provides a complete numerical simulation roadmap for future testing of UMST-X² through high-resolution cosmological modeling.This document represents the extended 50-page theoretical version of the model.
