OT: Gravity, Dark Energy, Universal expansion

It wouldn't be that hard to predict the suns' position in eight minutes.

So. If gravity is found to travel at c and the earth orbits the suns' actual position...Could gravity be 'connected' to the object it came from?

I'm confused. So there's both experiments that show that gravity is indeed travelling at the speed of light( or close to it ), and actual observations of the opposite?

Then that would indicate, as narf says, that there's some sort of connection to the object it came from. Perhaps gravity 'predicts' where the sun is going to be at the moment it reaches earth?

So if something was to suddenly push the sun out of its original and predictable path, it might take a while before gravity would catch up and start pulling us in the right direction again.

That's what people are saying. I have little knowledge of the situation - Just trying to make sense of it.
