Beginning in the 1970s studies of the redshift effect at Steward Observatory and the National Radio Astronomy Observatory developed evidence that the redshift was an intrinsic non-dynamical property of galaxies. Some of the introductory work was done at Lowell Observatory. A summary of some of the key professionally published references and evidence is presented. More details may be found at SASTPC.org where summary seminars and published professional references may be accessed. A comprehensive book on the subject is in preparation as is a cosmology based upon properties of space and time consistent with the observational evidence.
