Abstract
In a recently published article, Rahman and Banerji (1985) have shown that certain Friedmann-Lemaître-Robertson-Walker cosmological models with zero cosmological constant in the scale covariant theory of Canutoet al. (1977) do not have an observable singularity of infinite density in the beginning. This is in contrast to the corresponding general relativistic models, each of which has a big-bang singularity (see, for example, Ellis, 1971). In this note we show that the cosmological models in the scale-covariant theory which have been considered as possible viable models of the Universe by Canuto and his co-workers each possesses a singularity where the energy density diverges.
