I read that one of the most accepted proofs that gravity waves have energy is Richard Feymann's : imagine beads on a rod, gravity waves can move the beads creating friction and heat so they must have energy.
Why does the heat creation make this such a great proof? Isn't it obvious that if they can accelerate mass than they must at least have potantial energy? I know that I must be missing something here. Can someone please explain?
