Sky surveys for multi-messenger sources in the coming decades hold exciting prospects for understanding the nature of dark matter, primordial fluctuations, and gravitational wave sources. Predictions with control over model-independent uncertainties will be crucial for meaningfully interpreting data, and presents an opportunity for particle physicists to make an impact through novel application of tools such as renormalization, effective field theory, and scattering amplitudes. I will describe how quantum field theory enables precision physics in this new arena with three examples of state-of-the-art predictions: the gamma ray spectrum from annihilating dark matter, the statistics of cosmological density fields, and the inspiral of binary black holes.
