#SpaceWatchGL Interview: Hunting Gravitational Waves, An Interview With Professor Catia Grimani

Like all waves, gravitational ones transport energy, producing perturbations. We can visualize them by imagining a rope which we hold at one end and is tightly fixed on the other one; when we give a vertical impulse to it, we produce a perturbation -- a "wave" -- that propagates forward to the other end.
