Physics

There are three possibilities for the shape/curvature of theuniverse: positive curvature (closed), negative curvature (open),and flat curvature. These all imply different things about theultimate fate of the expanding universe. What kinds of observabletests could cosmologists use to distinguish one curvature from thenext? Please write a detailed paragraph explaining what kinds oftheory/observations cosmologists would have to make to determinethat the universe has negative curvature (open)?
