On negative mass in inflating universes

Abstract: We consider negative mass solutions in inflating universes. These universes correspond to asymptotically de Sitter space-times. We show that negative mass makes perfect physical sense and could be of relevance in the early universe.Résumé : Nous évaluons les solutions de masse négative au problème d'un univers en inflation. Ces univers correspondent asymptotiquement à des espace-temps de de Sitter. Nous démontrons que la masse négative est physiquement parfaitement acceptable et qu'elle pourrait être pertinent… Show more
