The first part of this question is new to me. I would think that if gravity can travel at the speed of light then it would follow the same laws of relative motion. Wether the two bodies are at rest or moving at a high rate of speed the attraction between the two would be the same. But what if the objects are approaching the speed of light, would the gravity field start to deflect from center? If this is true then maybe you would see a diffrence. Then again maybe not. You would think both fields would deflect the same amount.

The second question I have been thinking about for awhile now. I think if a mass would suddenly disapear, then the gravity field would collapse at the speed of light. For a moment, until the field totally collasped, you could witness gravity reverse it self. Objects left behind would be pulled away from the center of the vanishing object.

Let me know what you think.
