### Abstract

This will be a talk for a general audience explaining the dual role that the scalar curvature plays in differential geometry and in general relativity. Both subjects motivate questions about the geometric structure of spaces with scalar curvature bounded from below. We will describe some of these questions by analogy with similar questions for surfaces where the answers are largely known. In the physical case of dimension three we only have partial knowledge and many questions remain.
