The shape of the universe, in physical cosmology, is the local and global geometry of the universe. The local features of the geometry of the universe are primarily described by its curvature, whereas the topology of the universe describes general global properties of its shape as a continuous object. The … Zobraziť viac As stated in the introduction, there are two aspects to consider: 1. its local geometry, which predominantly concerns the curvature of the universe, particularly the observable universe, and 2. its global … Zobraziť viac The curvature is a quantity describing how the geometry of a space differs locally from the one of the flat space.
