grad students that should know things by now (like me!): [though in my defense, I have not had any GR yet, only what I've picked up in some books] My 2 questions: The effect of our time distortion from being near the earth is cool and all, can I assume we have a similar GR effect from being "near" the Sun? Is the effect any different because on the earth we are held at a potential by a normal force(ground) while around the Sun we're "held" equipotential by our elliptical orbit (which is moving, and thus constantly accelerating)? If the earth stopped rotating, it would change some correct? Because we lose some acceleration? I care not about magnitudes, I know it may be very small.
