A remarkable connection between the loop expansion of quantized gravity and classical general relativity allows for the computation of two-body dynamics in general relativity using a number of new amplitude tools developed in recent years. The resulting expansion is known as Post-Minkowskian (in contradistinction to Post-Newtonian) and the new method promises to overturn all previously used techniques for analytical calculations of gravitational wave signals of two merging black holes. I will outline the program and illustrate with examples of the calculation of classical gravitational scattering angles.
