Web[6] discovered the singularities in the FRW model. At the epoch of big bang, the entire three-surface shrinks to zero volume and the densities and curvatures grow to infinity. Hence by FRW models, the universe has an encompassing space-time a singularity during the big bang at a finite time in the past. 2 Earlier Concepts about the Universe WebLet’s go back to the FRW metric in Eq. (2.1). There, the scale factor a(t) depends on time, and it describes the situation that the radius of S2 evolves in time. As the radius changes in time, distance between any given two points on the sphere also changes with the same rate. This is the essence of the FRW world model!
