If Venus can be considered to be spinning against the gravitational field could this explain the longer duration of its day. In turn could this give us a hint at the mechanism of gravitation?
-
The fact that the angular rotation of Venus on its axis is opposite (and nearly equal) to the rotation of Venus around the Sun is definitely one factor that contributes to the very long duration of a day on Venus (http://en.wikipedia.org/wiki/Venus#Orbit_and_rotation), at about 4 Earth-months.
The length of a day on Venus has changed measurably since the first satellites visited it in 1990. The length of the day is thought to be affected by heating and expansion of the atmosphere (as is Earth's rotational period).
This may give us some ideas about gravitational/tidal locking of orbits, but I don't see how it would give us deep insights to the nature of the graviton, gravitational waves, or anti-gravity.

I don't think we'll have answers unless gravitational waves are detected. Theories just can't be tested.

Could the gravity probe b data show that it is the opposing vortices of the sun and venus that causes the slow rotation? See the video here:
