This model is sometimes called the Standard Model of modern cosmology, although such a description is also associated with the further developed Lambda-CDM model. Robertson and Arthur Geoffrey Walker – are variously grouped as Friedmann, Friedmann–Robertson–Walker ( FRW), Robertson–Walker ( RW), or Friedmann–Lemaître ( FL). Depending on geographical or historical preferences, the set of the four scientists – Alexander Friedmann, Georges Lemaître, Howard P. The general form of the metric follows from the geometric properties of homogeneity and isotropy Einstein's field equations are only needed to derive the scale factor of the universe as a function of time. The metric describes a homogeneous, isotropic, expanding (or otherwise, contracting) universe that is path-connected, but not necessarily simply connected. ) is a metric based on the exact solution of the Einstein field equations of general relativity. The Friedmann–Lemaître–Robertson–Walker metric ( FLRW / ˈ f r iː d m ə n l ə ˈ m ɛ t r ə .
