Scientific paper

A new method for measuring the red shift of quasars is used to calculate the distributions of quasars in the universe, as a means to define the form of the universe in its earliest times. The survey was done at Cerro Tololo using a low dispersion prism and photographic plates with fine grain and high contrast. The wideness of the emission lines indicates that some of the gas around a quasar moves at 10,000 km/sec and is hotter than in nebulas. The relatively large distances from earth to the quasars is taken as evidence that processes that created quasars were more active in the early universe than they are recently. The Cerro Tololo survey examined the distribution of quasars with a red shift approaching the present red-shift limit of 3.53 and results consistent with a random distribution were obtained, supporting the hypothesis of a homogeneous universe.
