Constraints on Decelerating Cosmologies
In a steadily decelerating Universe which is matter dominated but open with a density ratio to the critical density 0.26, H0t0 < 1 (Peacock 1999). A Universe which is accelerating now, and has 0.26 and a vacuum energy density ratio 0.74, has H0t0 1 (Carroll, Press & Turner 1992). The uncertainty in the product of equations 1 & 2 can be calculated from the normally distributed errors in H0 and t0. Figure 1 shows the probability distribution for H0t0 for two assumptions: tf = 0 and 1 Gyr.
