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. -FER --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
