WebThe meaning of REDSHIFT is a displacement of the spectrum of a celestial body toward longer wavelengths that is a consequence of the Doppler effect or the gravitational field of the source; also : a measurement of a celestial body's redshift equal to the ratio of the … WebIn general, cosmological redshifts are not the same as Doppler shifts. Redshifts can be measured very accurately. A typical velocity measurement for a galaxy might be 12,540 ± 120 km/s, which corresponds to a redshift of z = v / c = 12,540 / 3x 10 5 = 0.0418.
