Scattering amplitudes in quantum field theory have received a lot of attention in recent years. We have learned that amplitudes provide a surprising link, known as the double copy, between Einstein gravity and Yang-Mills theory. I will describe how this link persists in the classical regime. Consequently we can determine certain gravitational waveforms from amplitudes, and also build on our understanding of classical solutions in gravity to learn about new classes of amplitudes.
