I agree with Doc. Al that, "For the simplified case of a uniform density spherical planet, the gravitational field varies linearly from 0 at the center to its full value at the surface." But, what is the effect, if any, on the shape and density distribution of such a sphere over time (e.g., billions of Earth years)?
For example, over such time would the sphere begin to sort itself by density (e.g., from least dense at the core to most dense at approx. r/2)? And if so, would the newly distributed density affect the shape of the sphere (e.g., from a solid sphere to a hollow one)?
