1.1 If ΩM = ΩT = 1, then ΩM(a) = ΩT(a) = 1 for all a(t). Structure formation never ceases as larger and larger regions of negative Newtonian energy detach from the expansion. The values of the Ω’s for the ΩM = ΩT = 0.3 and the ΩM = 0.3,ΩΛ = 0.7 models are shown in Fig. 1. Fig. 1 The solid lines show ΩM(a) and ΩΛ(a) for (ΩM = 0.3,ΩΛ = 0.7). The dashed line shows ΩM(a) for (ΩM = ΩT = 0.3). The universe remains matter dominated for a longer period in the first case 1 2...
