In a nutshell, the researchers used the detection of gravity waves to triangulate to where the waves came from. Within seconds came light from the same source.
For certain the light was pointing back to the location of the emission point. If the detectors were able to triangulate back to the same position in space, then the gravity waves did not tug the detectors toward the location of the emitting object, but toward the location where the emitter was at the time of emission. Neither the light nor the gravity waves provide any information about where the emitting object has moved to at the time of observation.
Therefore, is the force of gravity shared between two objects delayed by the propagation of the gravity waves? If so, the two objects are not actually pulling on each other. The waves are not attached to the emitting objects.
So, my first confusion is: Even if the reaction is just a matter of space being warped, how do two objects dealing with a delayed exchange of energy obtain a stable and sustainable orbit?
My second is: Could an object appear to be getting pulled toward nothing at all? It could be getting pulled toward a position where a gravity emitter used to be.
(I'm sorry I was not clear, and maybe I am still not. I deeply appreciate your patience.)
