An age of 9.3 + or - 2.0 Gyr is derived for the Galactic disk on the basis of comparisons between the sudden drop in the observed luminosity distribution and theoretical evolutionary white dwarf models and allowance for a mean prewhite-dwarf lifetime of 0.3 Gyr. To obtain the age of the universe, the time between the big bang and the first appearance of stars in the Galactic disk is added. The age of the universe is estimated to be 10.3 + or - 2.2 Gyr. 39 references.

The age of the universe is estimated to be 10.3 + or - 2.2 Gyr, derived from the Galactic disk age and the time between the big bang and the first appearance of stars in the Galactic disk.
