The footnote for #8 says that the calculations are "complicated or contrived", and that the fundamental formula was "conformed" to match the observed perihelion precession.  No one doubts that the derivation is complicated.  But "conformed" seems to say that something was "tweaked" to match the precession.  The formula is complicated to solve but simple to write: <math>G_{\mu\nu} = 8 \pi K T_{\mu\nu}\,</math>.  There's nothing in it that can be "tweaked"--not 8, not pi, and not K (Newton's constant of gravitation.)[[User:JudyJ|JudyJ]] 17:08, 21 January 2012 (EST)

:Yep, this is also confusing to me. Does Andy Schlafly know relativity? As you said, nothing can be tweaked in that equation (to "conform" to whatever events). The tensor that represents curvature has to have divergence 0, so that energy-momentum is locally conserved, and the 8*pi*G is determined from the fact that it has to reduce to Newtonian gravity in the weak-field limit.
