Gravitational Physics and Scattering Amplitudes

Scattering amplitudes have recently found a new application to classical gravitational-wave physics. In this talk I will discuss why amplitudes can be useful in this area, and outline how to extract classical observables from the amplitudes. We will see that the basic aspects of classical physics in turn yields interesting new constraints on the structure of multiloop, multileg amplitudes.
