determines the gravitational wave-form at late and early retarded time, generated during a
scattering or explosion, in terms of the four momenta of the ingoing and outgoing objects.
This result was 'derived'earlier by taking the classical limit of the quantum soft graviton
theorem, and making some assumptions about how to deal with the infrared divergences of
the soft factor. In this paper we give a direct proof of this result by analyzing the classical …
