You can get redshift both through gravity and through motion (apparent motion).Simons said:forgive me if I am wrong, but isn't red-shift the result of the doppler effect? (red=lower frequency, meaning a cosmic body is moving away from the viewer, thus increasing the wavelength of light emitted in the opposite direction of motion, likewise blue-shift means an object is moving towards the observer and is producing a perceived higher frequency of light) ??
