SUMMARY
The discussion centers on the Ricci Tensor Equation as presented in Zee's "Einstein's Gravity in a Nutshell," specifically on page 363 during the derivation of the Schwarzschild solution. The equality of the right-hand side (rhs) and left-hand side (lhs) is established by noting that the solution is independent of the time coordinate, leading to the vanishing of derivatives with respect to that coordinate. The factor of 2 arises from the dual possibilities of the parameters sigma and kappa taking values of r and t, which can be represented in two distinct ways.
