The Cosmical Constant and the Age of the Universe

Abstract:

The present investigation deals with a question how much the age of an expanding universe can be lengthened by the introduction of the cosmical constant in the relativistic cosmology. The age and the redshift-magnitude relation of galaxies are calculated for various values of the deceleration parameter and the cosmical constant, which characterize the universe models. The comparison with the observational data on the redshift-magnitude relation indicates that, if the effect of the evolution of galaxies is neglected, the age is not beyond 13 ×109 years and that cosmical constant can not be greater than 6 ×10-55 cm-2.
