Abstract
IT has long been recognized that isotropic models of the world are singular. The models, be they Newtonian or based on Einstein's equations of general relativity, lead to the prediction of at least one moment in the history of the Universe with an infinite density of matter. A similar singularity has been shown to occur as a result of spherically symmetric gravitational collapse of a cloud of dust1. For some time it was thought that the singularities might be a consequence of the high symmetry of the models.
