=tinsley diagram= The Tinsley Diagram, devised by Deborah Tinsley, is a diagram used in cosmology which plots H_0t_0 against log(sigma_0 ), where H_0 is the current value of the Hubble constant, t_0 is the current age of the universe, sigma_0 is the density parameter related to the more modern density paramter, omega_0 by omega_0=2sigma_0. Lines are plotted for various values of q_0, the deceleration parameter. The line for k=0 can be plotted to differentiate the regions of positive and negative universal curvature. The line for lambda=0 can also be plotted, to separate regions of positive and negative values.

A useful implementation of the Tinsley diagram is found by calculating the current value for H_0t_0 (explain methods) and plotting this line. Since the current age of the universe is always greater than the age of any object we see, we can say t*
