Peter, I'm going through your derivations in #249, and just a prelimenary query. Not following how you get the simplification of that first G

(1/r

next perform d/dr operation on K

(1/r

1/(r

Can't see this coming out to what you get. Past April Fools here but maybe effect lingering for me (the next bit, G

_{00}expression. When I try it goes like this:(1/r

^{2})(1-1/K) - (1/r)d/dr(1/K) = 8πρ (that's my version of what we start with)next perform d/dr operation on K

^{-1}, before further grouping of terms ->(1/r

^{2})(1-1/K)+(1/rK^{2})dK/dr = 8πρ ->1/(r

^{2}K)(K-1+r/K^{3}dK/dr) = 8πρCan't see this coming out to what you get. Past April Fools here but maybe effect lingering for me (the next bit, G

_{11}-> dJ/dr = (.....) part looks fine). :yuck:
