If dark matter only interacts with baryonic matter gravitationally, would it pool at the center of stars, planets, and other ordinary mass objects? That is, suppose there was a particle of dark matter, whatever that is, at rest at the surface of the earth. Since it would not interact with normal particles, it seems that it would gravitate down towards gravitational equilibrium at the center of the earth. If so, would we detect such pooling by finding gravitational forces larger than would be predicted by Newtonian physics? Or does the gravitational constant already include, without realizing it, whatever dark matter has pooled?
