Abstract/Summary Hubble's Law, v = HD (recession velocity is proportional to distance), is a theoretical result derived from the Friedmann-Robertson-Walker metric, v = HD applies at least as far as the particle horizon and in principle for all distances. Thus, galaxies with distances greater than D = c/H are receding from us with velocities greater than the speed of light and superluminal recession is a fundamental part of the general relativistic description of the expanding universe. This apparent contradiction of special relativity (SR) is often mistakenly remedied by converting redshift to velocity using SR. Here we show that galaxies with recession velocities faster than the speed of light are observable and that in all viable cosmological models, galaxies above a redshift of three are receding superluminally.
