Abstract

THE age of the Universe is one of the most interesting cosmological parameters. The fact that the age is finite has intriguing philosophical as well as physical implications. An accurate age when compared to the present expansion rate parameter, the Hubble constant H0, can in the standard big bang model even determine the large scale structure of the Universe, that is decide whether the Universe is open or closed. This note combines the various constraints of the traditional dating methods in the context of the standard cosmological model to see which age can satisfy them all. This simultaneous solution is more restrictive than the previous ranges on the age of the Universe, and agrees with the description of the Universe given by Friedmann.
