"Speed" of gravity. Whats the problem. I keep finding stuff on the net about the speed of gravity and how some people contest it should be c, the speed of light. Now I lean more towards an infinite "speed" of gravity, but I really cant see why gravity should be restricted by c. People say that nothing can travel faster than the speed of light. But objects appear to expierience gravitational force direction changes instantly. So what's the problem. Nothing has travelled faster than the speed of light. Two object have just experienced accellerations at the same time. Relativity says that masses cannot travel at the speed of light relative to one another, but why should this apply to forces. No Thing has travelled faster than light.
