If accelerated objects emit gravitational waves, and gravity is said to have an infinite reach, is it fair to say that all space would contain gravitational wave energy, coming and going in all directions, from a potentially infinite history of the relative motion of celestial objects?All space does contain gravitational wave energy simply because all space is near accelerating objects. But gravity waves travel at light speed, so a given event can only reach as far as the event horizon, just like light.
Gravity on the other hand is a field and does not propagate at some speed, so gravity has no finite bound to its effect.
Information can be transmitted via gravity waves, but not via gravity.
