That, Paul, is what's known as an "oops" on your part. The Lense-
Thirring Effect does in fact predict rotational inertial dragging of
frames in the vicinity of a rotating body, and it is an effect that
has been experimentally confirmed. While the amount is infinitesimal
for a mass as small as the Earth (assuming it to be rotating, which I
disavow), it is nonetheless non-zero. A rotating body DOES have a
mechanical influence on the periods of objects around them -- it's
generally too tiny to detect.
So, while you might be correct on raw Newtonian grounds, in the
absolute empirical scheme of things the only thing exposed by your
post is your own weakness in physics. True, the magnitudes of the
Lense-Thirring Effect likely don't affect your primary argument, BUT
your blanket statement goes too far in asserting zero influence.
Don't think to say that Newton "is good enough." Long's 1970
determination of G using a Cavendish torsion balance, set up with
precision elemental rings, showed deviations in the value of G (based
on Newtonian theory) of 0.37%. That means Newton is off by a whoping
1 part in 300, and this error was readily detectible in an earth-
bound laboratory. Einsteinian theory can't explain that anomaly
either, so GR is likewise an unreliable codification of gravitation.
That said, I'm still interested in hearing from Robert as to what HE
meant by his comment (perhaps it had something to do with accounting
for elliptical orbits, which would entail accelerations/decelerations
if they were assumed to be circular, or he sees something else
entirely that needs to be factored in...)

Martin
