Just watched Intersteller and my mind started running wild with all sort of fun thoughts. So I'm not sure how serious of a questions this is, but I got to thinking if it's possible to use gravity waves as a form of communication. And in turn, started wondering how said waves could be detected. The way I think of matter on spacetime is like that usual analogy of marbles on a rubber sheet. And I think of phenomena like quantum tunneling as marbles bouncing over each other when hit hard enough, like billiard balls bouncing off a pool table if hit too hard at an odd angle. This would be made easier, I would think, if the surface on which the marbles/billiard balls are rolling were not perfectly flat, but perturbed in some way. So I was wondering if passing gravity waves could have an affect on the probability of a particle crossing/"tunneling through" a wall. I mean if you had an isolated container at constant temperature/pressure with a thin wall on one side opposite a detector, is it possible that the number of particles that hit the detector on the other side could be affected by passing gravity waves?
