Gravitational Dynamics from Scattering Amplitudes

Gravity is a fundamental force but so weak that we have limited
understanding of its extreme interactions. A recent exciting development
is the detection of collisions of black holes in the Universe. These
phenomena witnessed by the Laser Interferometer Gravitational-Wave
Observatory (LIGO) have refreshed enthusiasm for exploration of
gravitational interactions and stimulated critical advancement of
precision analysis of merger events. We will in this talk outline how to
derive dynamics in general relativity by application of modern on-shell
amplitude techniques and discuss how such methods can complement
existing technology and facilitate computational progress.
