Let's begin by discussing the source of Newtonian gravity. Later, we can also touch on the source of Einsteinian gravity. So, what substance generates a point mass? If Euclidean space were a foliation with a typical fiber in the form of a 3-dimensional sphere, then the source of gravity would be the vector (covector) field generating this foliation. Locally, such a vector field can be represented as a linear vector field orthogonal to the unit 3-sphere of 4-dimensional space. Then, the Newtonian gravitational potential is the angle (hyperbolic) of deviation of the vector field from orthogonality to the 3-sphere. In the limit, the angle tends to infinity, and therefore the source of a point mass is a vector field tangent to the 3-sphere.
