Abstract
The energy-momentum radiated in gravitational waves by an isolated source is given by a formula of Bondi. This formula is highly nonlocal: the energy-momentum is not given as the integral of a well-defined local density. It has therefore been unclear whether the Bondi formula can be used to get information from gravity-wave measurements. In this article, we obtain, from local knowledge of the radiation field, a lower bound on the Bondi flux.
