Scientific paper

The article reviews the problems of a dynamic or static universe, isotropy throughout the universe, the Cosmological Principle, the Principle of Equivalence, and redshifts. The problem of whether the rate of expansion is greater than the velocity for escape of galaxies from the universe, and the related problem of the total mass and average mass density of the universe, are discussed. The importance of the deceleration parameter, and the difficulties in measuring or estimating the intrinsic brightnesses of galaxies, are emphasized. The author cautiously infers that the universe contains too little mass to stop indefinite expansion.
