I would like to see this sensitive gravitometer and how it works in orbit.
BTW, isn't the Sun actually the "source" of that pull, and Earth is rotating around it's own axis?
When you point your finger in the direction of the Sun (and keep it pointed in that direction for a while), your finger is actually tracking the Sun.. (compensating the rotation of earth).
So, the Sun's direction in the sky at any moment is exactly where it appears to be... and not ahead of it's image.
