In 1973, astronomer [[William G. Tifft]] was the first to report evidence of this pattern. Recent discourse has focused upon whether [[redshift survey]]s of [[quasars]] (QSOs) have produced evidence of quantization in excess of what is expected due to [[selection effect]] or [[galaxy cluster|galactic clustering]].<ref>{{cite journal |last1=Trimble |first1=V. |last2=Aschwanden |first2=M.

Redshift quantization is a controversial topic considered to be in the fringes of modern astronomy. Though the idea is generally discounted by the large majority of astronomers, peer-reviewed publications and discourse on the topic still continue to the present day.<ref>{{cite book |last1= Babu |first= G.
