Abstract: The era of gravitational wave science is unfolding in spectacular fashion, with multiple detections reported by the LIGO-Virgo-KAGRA collaboration and many more anticipated from future observatories such as LISA and the Einstein Telescope. Motivated by these experimental breakthroughs and the expected scientific output, the community has embarked on a concerted effort to construct high-accuracy waveform models for the emission of gravitational waves from binary systems. In this talk, I review how ideas and techniques from particle physics — such as effective field theory methods and modern integration techniques from collider physics — have impacted our understanding of the two-body problem in general relativity.
