Next, understand the definitions and the similarities (the links) between the two;
In geometry, curvature may be defined as the mathematical obstruction within a curvilinear coordinate system, so that it cannot be transformed into a flat coordinate system. In the general theory of relativity, gravitation may be defined as the obstruction of tidal forces within a gravitational field, so that it cannot be transformed into a field of flat spacetime.
Then the 'Connection' (The Christoffel symbols), between energy and negative divergence.
ie. Curvature Tensor = Energy Momentum
roughly speaking; The metric must equal the E=mc^2 of all the mass within a given space (3D) and over a given time.

Valiant effort. Why bring real science into this pathetic discussion. Most people get lost with integrals let alone matrices. They would far more prefer to argue from a totally nebulous basis. It makes hand waving almost acceptable.
