Emergent Spacetime from Matter: A Unified Framework

We explore a framework in which spacetime emerges locally from matter, rather than existing as a pre-defined background. Gravitational phenomena arise from spatial inhomogeneities between locally generated metrics. We present the mathematical structure, show consistency with General Relativity in the weak-field limit, describe the global evolution of the cosmic metric, and discuss observable consequences including early galaxy maturity and redshift measurements. The model provides a unified explanation for apparent cosmic acceleration and recent JWST observations of unexpectedly mature high-redshift galaxies.
