Narlikar, J.

It is shown that the cosmological model based on this solu- tion satisfies all the observational tests and thus is a viable alternative to the standard big-bang model. The present model is free from singularity and particle horizon and provides a natural ex- planation for the flatness problem. We argue that these features make the creation-field cosmologi- cal model theoretically superior to the big-bang model.enCosmologySingularityArticle
