Abstract
Recent conceptual advances have allowed us to delve further than ever before into the quantum corrections to scattering amplitudes, perhaps nature’s most perfect microscopic structures. Doing so we have uncovered surprisingly powerful relations known as the color-kinematics duality, and associated double-copy structure. Universal to many theories from the entirely formal to the utterly effective, these structures apply to processes from pion scattering to perturbative QCD to classical black hole scattering and to cosmic inflation. I will introduce the field of scattering amplitudes as a conceptual laboratory for probing the invariant predictive content of physical theory. I will discuss how we have made progress on one of the boundary pushing questions driving this progress: the UV behavior of maximal supergravity, as well as sketch some exciting open roads ahead.
