A novel type of matter coupling in the Einstein gravity is discovered. This type of matter coupling is theoretically self-consistent in the sense that all constraints in the Hamiltonian are preserved to be first class. At low energy scale it recovers the classic standard predictions of the Einstein gravity minimally coupled with matter content, including the gravitational potential and the equivalence principle, while at the high energy scale much richer phenomenology is granted. We predict a lower bound on the cross section between dark matter particles and Standard Model particles in this framework. The novel matter coupling may provide a resolution to the cosmological singularity problem.
