Simplified derivation of the gravitational wave stress tensor from the linearized Einstein field equations.

Abstract:

A conserved stress energy tensorfor weak field gravitational waves propagating in vacuum is derived directly from the linearized general relativistic wave equation alone, for an arbitrary gauge. In any harmonic gauge, the form of the tensor leads directly to the classical expression for the outgoing wave energy. The method described here, however, is a much simpler,shorter, and more physically motivated approach than is the customary procedure, which involves a lengthy and cumbersome second-o...
