where did you read that andy? it doesnt sound very plausible..
I can think of a test for the speed of gravity. If light and gravity travel at the same speed then as we rotate the sun we actually rotate the image of the sun, where it was 8 mins ago. This is because the sun is moving about the galactic center.
If gravity is faster (perhaps instantaneous) then we would be orbiting about the actual position of the sun while we would see the image of sun lagging behind. This would mean that our orbit would appear off center.
Giving this some more thought, apart from being incompatible with relativity, this seems non-nonsensical, it leads to orbits appearing unstable but not being unstable.
If there is a flaw in my logic please point it out.
