Abstract
Strittmatter, Faulkner and Walmesley1 have recently pointed out that quasars with large red-shifts do not appear to be distributed isotropically. The quasars with red-shift z > 1.5 are mainly confined to two regions, one near the North Galactic Pole and the other in the South Galactic Hemisphere. These groups each have an angular diameter of about 30°. Quasars with intermediate z also appear to be distributed anisotropically, but with a larger angular diameter. Strittmatter, Faulkner and Walmesley have suggested that, if future observations confirm these trends, then either (a) the universe is anisotropic for z ≳ 1, or (b) quasars are not at cosmological distances.
