Abstract

Despite the rapid strides made in observational and theoretical astronomy, particularly in our century, there are two fundamental questions respecting the universe that defy solution. One pertains to the age of the universe, that is, did the universe have a beginning and therefore have a finite time-scale or has the universe existed without beginning. The other question deals with the dimensions of the universe, that is, is the universe infinite or not. For the time being no satisfactory proof or disproof has been offered either on purely logical grounds or through empirical evidence revealing whether the universe is boundless and eternal or not. It is for this reason that cosmologists must resort to a variety of unverifiable philosophic postulates in the hope of constructing a cosmological model that correlates the known laws of the physical world with the observed facts of nature and simultaneously presents a consistent picture of the universe as it changes in time.
