On the initial singularity and extendibility of flat quasi-de Sitter spacetimes
Abstract Inflationary spacetimes have been argued to be past geodesically incomplete in many situations. However, whether the geodesic incompleteness implies the existence of an initial spacetime curvature singularity or whether the spacetime may be extended (potentially into another phase of the un...
