Abstract:
The possibility of the expansion of clusters of galaxies has been considered from two points of view. First, if one assumes that the redshift of galaxies reflects velocity of recession, the question arises do the members of clusters of galaxies participate in the general expansion indicated by the law of redshifts, with the clusters themselves expanding In a study of this problem, Neyman and Scott 1 developed a statistical kinematic test of the stability of systems of galaxies. In 1953 the test was applied to the twelve galaxies in the Coma Cluster for which the necessary data radial velocities and magnitudes were available. There was no indication of expansion.
