Title: Is it a small world after all? Searching for the shape of the universe
Abstract: 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.
