G Model: A Fundamental Causal-Spacetime Framework for Gravity

The G Model investigates whether gravity can emerge from the structure and dynamics of spacetime itself. It proposes a minimal local causal structure built from four balanced lightlike directions and six pairwise causal connections.

The framework distinguishes matter from spacetime, treats matter as a disturbance of the causal fabric, and retains failed approaches and no-go results as part of its research record.
