[Rebond primordial comme alternative à l'inflation]
Quoique le paradigme inflationaire soit maintenant communément accepté comme représentant la meilleure explication des données cosmologiques, il n'est pas pour autant possible de dire qu'une telle phase soit avérée. Pour s'approcher d'une telle conclusion, on peut suivre deux chemins différents : on peut explorer les conséquences de l'inflation pour la pousser dans ses derniers retranchements, ou bien, au contraire, étudier en détail les alternatives possibles. La première option faisant l'objet de la plupart des contributions de ce volume, nous nous concentrons ici sur la seconde, et présentons les modèles dans lesquels une phase de contraction est suivie d'un rebond conduisant à notre époque d'expansion.
Although the inflationary paradigm is the most widely accepted explanation for the current cosmological observations, it does not necessarily correspond to what actually happened in the early stages of our Universe. To decide on this issue, two paths can be followed: first, all the possible predictions it makes must be derived thoroughly and compared with available data, and second, all the imaginable alternatives must be ruled out. Leaving the first task to all other contributors of this volume, we concentrate here on the second option, focusing on the bouncing alternatives and their consequences.
