DESCRIPTION:The remarkable detection of gravitational waves by
  the LIGO/Virgo\ncollaboration has opened a new wi
 ndow into the cosmos.  In this\ncolloquium we expl
 ain how particle theorists can help out with\ncalc
 ulations directly relevant for gravitational-wave 
 emission from\ncompact astrophysical objects.  The
  past decade has seen enormous\nadvances in our ab
 ility to compute quantum scattering amplitudes\nma
 king seemingly impossible calculations tractable. 
  These advances\ninclude ideas such as the duality
  between color and kinematics\,\ndouble-copy relat
 ions and generalized unitarity\, and improved\nint
 egration methods.  After introducing these concept
 s\, we explain how\nthese ideas are transferred to
  the state-of-the-art calculations for\nthe binary
  black hole inspiral problem.
