Emergent Gravitational Constant from Residual Universes: A Numerical Exploration of Environment-Dependent Gravity

This preprint investigates a numerical framework in which the gravitational constant itself is not imposed a priori but emerges from the collective dynamics of simplified residual universes. Using N-body simulations of idealized galactic systems, we show how an effective gravitational constant can arise from local interactions and from the surrounding gravitational environment. The model explores how spatial and environmental variations of this emergent constant may reproduce qualitative features of galaxy dynamics without invoking additional dark matter components. This work is exploratory and aims to provide a computational testbed for studying gravity as an emergent phenomenon rather than a fundamental fixed parameter.
