High-precision theoretical predictions for the motion of binary black hole or/and neutron star systems are essential for maximizing the discovery potential of current and future gravitational-wave observatories, such as LIGO-Virgo-KAGRA, Taiji, TianQin, and Einstein Telescope. Surprisingly, the most powerful analytic toolkit for the classical problem originates from Quantum Field Theory. This presentation explores how Effective Field Theory approaches combined with state-of-the-art Feynman multi-loop techniques have revolutionized our ability to solve the gravitational two-body problem with unprecedented analytical precision.
