## Main Question or Discussion Point

As I understand it, Newton considered the influence of gravity between two objects to be instantaneous.

Now it would appear that gravity has a speed limit. If the earth is influenced by the sun from where it was 8 minutes ago, how does the earth keep up with a traveling sun?

Does relativity and frames of reference play a mathematical role in this? What about simple vector analysis?

Thank you in advance.
