Hello, Sorry if this is in the incorrect forum. I've come across a discussion that has made the following argument, but I'm unable reconcile the views. I've searched within and without and have come across no answer that addresses this specific claim. To begin, from my understanding gravity has infinite range. In a universe comprised of only two objects at any finite distance, with enough time they will collide. The argument is that galaxies receding from other galaxies faster than c cannot be influenced by gravity from those galaxies since gravity travels at the speed of c and would never reach them. I thought the force of gravity would only weaken, not outright cease from lack of contact. Is this an "exception" to the model we have for gravity? Thanks for your time.
