FTP, what is this displacement in the lines of the spectra of certain galaxies towards longer wavelengths, most famous in its Doppler form?
One version of this phenomenon is caused by high gravitational fields, and likely causes the high values over 3 seen in quasars. Predicted by Einstein, this gravitational version is very similar to the more common version, which is usually given a value expressed as delta lambda over lambda, but for relatively low velocities of recession, the equivalent value v over c is used.
