## Metric Solves Grav. Gauss' Law (2/2)

- Write out the definition of the Christoffel symbol of the second kind:

- Static, so .
Diagonal, so
.

- Write out in terms of the components:

- This is the singular 1/R solution to the Poisson equation with canceling
exponentials.

A physically-relevant, dynamic metric solves the GEM field equations.
