Titre Is it a small world after all? Searching for the shape of the universe
Résumé We know the average spatial curvature of the universe is very small, but that is just simplest aspect of its large-scale shape. What is the topology of the universe? So far our searches for topology have yielded only limits. But when the search space is multi-dimensional, and the searches are specialized, how constraining are they? Meanwhile there are tantalizing hints in the large-angle anomalies of the cosmic microwave background that they may be signs of non-trivial cosmic topology. We will discuss.
