Gravitational red-shift according to the Bi-metric theory of gravitation.
Abstract
Gravitational redshifts are calculated according to the bimetric theory of gravitation (BM) for pulsars, using a broad range of equations of state (EOSs), as well as for quasars, assuming constant density. It is shown that the reported pulsar redshift of z = 0.28 rules out in BM (as well as in General Relativity (GR)) the soft EOS of Canuto and Chitre (1974). Quasar gravitational redshifts may be very large in BM (in contrast to those in GR), and the large observed quasar redshifts can thus be gravitational in origin.
