Cosmology of Einstein-de Sitter Universe

The graphs show the expansion of a flat, matter-dominated universe as described by the Friedmann equation. In a flat universe, the cosmological parameters, matter density and vacuum density , are related by +=1. Therefore it is sufficient to vary only . The "shift" slider allows you vary the expansion rate of the initial curve =1 toward the actual value =1.
