I’ve heard of a light cone, but never heard the term gravity cone. Seems to me a light cone is kind of misnamed or arbitrary. It’s more like an information cone. There’s nothing special about light. You just can’t feel things that happen outside the light cone. So if a big object moves outside your light/gravity cone, you’ll never feel the gravity wave. Should it just be thought of as a gravity cone? Or a causality cone? Or an information cone?

Am I misunderstanding this concept?
