Abstract
THE purpose of this report is to point out that recent measurements1 of the red-shifts of quasars provide the most decisive evidence so far obtained against the steady state model of the universe. The previous evidence2,3 consisted mainly of the anomalously4 steep slope of the log N–log S relation for quasars (N is the number of sources with flux density greater than S). This evidence is ambiguous, however, because one could argue5 that many of the quasars may have zero red-shifts and be situated inside our Galaxy. Their log N–log S relation would then have a purely local significance. If we can restrict the analysis to quasars of known red-shift we avoid this ambiguity, provided that we interpret the red-shift as being cosmological in origin, which in this communication we shall do.
