✦ Synopsis
In Rosen's "bimetric" theory of gravity the (local) speed of gravitational radiation u. is determined by the combined effects of cosmological boundary values and nearby concentrations of matter. It is possible for v. to be less than the speed of light. I show here that emission of gravitational radiation prevents particles of nonzero rest mass from exceeding the speed of gravitational radiation. Observations of relativistic particles place limits on v, and the cosmological boundary values today, and observations of synchrotron radiation from compact radio sources place limits on the cosmological boundary values in the past.
