The SAGEX review on scattering amplitudes Chapter 14: Classical gravity from scattering amplitudes

Abstract Scattering amplitudes have their origin in quantum field theory, but have wide-ranging applications extending to classical physics. We review a formalism to connect certain classical observables to scattering amplitudes. An advantage of this formalism is that it enables us to study implications of the double copy in classical gravity. …
