Abstract
The improvement of the Friedmann models of the Universe with the inclusion of non-interacting radiation was first made by Lemaitre in 1927. These ‘improved Friedmann models’ are discussed and it is shown that they require modification in the early Universe because of pair production at high temperatures.Keywords
