I know the general premise is that the "speed of gravity" is equal to that of light speed, but something that doesn't quite make sense to me is this;
Space itself can, and does expand faster than the speed of light right? By proxy it should be able to contract faster than the speed of light. Since a massive object causes gravity by warping space-time around it, that process of warping space-time should also be capable of moving faster than light. Therefor if you could magically disappear a star or magically make a star, the reach of the gravity and it's effect on distant objects should be able to travel as fast as the universe is expanding or as fast as the universe is capable of expanding. So the speed of gravity so to speak should be limited only by the maximum expansion rate the universe itself is capable of attaining.
Now I know this is wrong. People much smarter than I have worked on it and come to the conclusion that the correct answer is C. I'm hoping some of those people much smarter than I who read these forums can explain why that is.
Thanks in advance!
