A DESI universe with time-dependent dark energy is 119 Myr younger than a LambdaCDM universe
Abstract
On the basis of their redshift and Lyman-alpha measurements, the Dark Energy Spectroscopic Instrument (DESI) collaboration suggest that dark energy varies with the scale factor a as de(a)= \, a-3(1 + w0 + wa) e-3 wa (1-a)de,0 in which w0 = - 0.752 0.057 and wa = - 0.86+0.23-0.20 . Such a DESI universe is 119 Myr younger than the LambdaCDM universe.
