    Dan, you wrote:
    "A gentleman I met recently claims to have made an instrument for measuring
    the gravitational field of the sun and moon. He states that when the
    gravitational field of the sun is directly overhead that this occurs  eight
    minutes before local apparent noon. This would indicate that gravitational
    field lines change instantaneously  while the speed of light lags behind."
    
    Ahh, the old "speed of gravity" shtick. If you want to lose yourself in a
    world of crackpots and ranting flakes, convinced that general relativity is
    a grand conspiracy, try googling "TvF" and "speed of gravity". But it's
    off-topic for this list, I think, so I won't go into it further. One place
    where it IS on-topic is the Compuserve SciMath Forum (which is open to
    anyone... you have to create an idea to post, but it costs nothing). You can
    find it here:
    http://community.compuserve.com/n/pfx/forum.aspx?webtag=ws-sciencemath .
    This is actually where the infamous "TvF" peddled most of his "speed of
    gravity" tall tales as far back as the late 1980s, and there are still a few
    people who remember those days on the forum.
