Some of information on this graph, developed for the article by Lawrence Krause of Case Western Reserve University in theJanuary 1999 issue of *Scientific American*, has been examined in similar graphs on the previous page. Six further comment: 1) the vertical axis denotes the density of the energy associated with the Cosmological Contant; the horizontal axis refers to matter density; 2) the yellow line is a plot of the possible combinations of Ω_{Λ} and Ω_{M}; it defines a Flat Universe and is a boundary between Open and Closed Universe; 3) the blue line divides Accelerating and Decelerating Universes, determined by the numerical difference between the two Ωs,
which leads to a statement about the relative strengths of gravity and expansion, thus indicating how expansion rates vary with time; 4) the red line predicts the long term history of a Universe that expands steadily; 5) the lower yellow dot describes a Standard Model Universe with no Cosmological Constant affecting it, and 6) the upper yellow dot positions a Universe with the current best estimate of the dark energy density at Ω_{Λ} = 0.7.
