ABSTRACT: The
nonlinear affine Goldstone model of the emergent gravity, built on the
nonlinearly realized/ hidden affine symmetry, is concisely revisited. Beyond
General Relativity, the explicit violation of general invariance/relativity,
under preserving general covariance, is exposed. Dependent on a nondynamical
affine connection, a generally covariant second-order effective Lagrangian for
metric gravity is worked out, with the general relativity violation and the
gravitational dark matter serving as the signatures of emergence.
