Gravity as a Response Field in Spacetime

We present empirical evidence that gravitational observables do not scale monotonically with mass and cannot be accounted for by mass-derived or collectively sourced spacetime curvature alone. Using CMB lensing-galaxy cross-coorlations, redshift stratification, structural and morphological controls, and extensive null tests, we show that gravitational coupling depends on environmental and organizational properties independent of total mass. These results motivate a response-field description of gravity, in which gravitational effects arise from the activation of a pre-existing fied rather than being generated directly by matter. All data and analysis materials required to reproduce the results are publicly available via a linked data archive.
