Query: The Geometric Gravitational Internal Problem   In a geometric unified theory there is an energy momentum equation, apart
from the field equations and equations of motion. The general relativity
Einstein equation with cosmological constant follows from this energy momentum
equation for empty space. For non empty space we obtain a generalized Einstein
equation, relating the Einstein tensor to a geometric stress energy tensor. The
matching exterior solution is in agreement with the standard relativity tests.
Furthermore, there is a Newtonian limit where we obtain Poisson's equation.
