where by (r, θ, φ) correspond to the spherical coordinate system. This metric has only two undetermined parameters. An In general dimensionless size scale factor R describes the dimensions scale from the universe as being a functionality of time (an increase in R would be the expansion on the universe),[152] in addition to a curvature index k describes the geometry. The index k is outlined to make sure that it normally takes only one of 3 values: 0, akin to flat Euclidean geometry; 1, akin to a space of good curvature; or −1, comparable to a space of good or negative curvature.
