Abstract Will and Eardley (1977) have concluded that systems such as the binary pulsar PSR 1913+16 could provide a test of the viability of the bimetric theory of gravitation since in the framework of that theory, such a system would emit dipole gravitational radiation (except in special cases), as a result of which the orbital period would increase rapidly with time. The present paper questions this conclusion by noting that the bimetric theory yields an essentially time-symmetric source field. It is argued that a physical system does not lose or gain energy by emitting gravitational radiation, that PSR 1913+16 should not lose or gain energy by emitting dipole radiation, and that the change in orbital period discussed by Will and Eardley would not be observed even if the bimetric theory were valid. The possibility is considered of distinguishing between the general theory of relativity and the bimetric theory on the basis of the effect of quadrupole gravitational radiation on the orbital period of PSR 1913+16.
