See details below

Explanation:

Following Lamaitre's Theory, the age of universe is depending of the moment of BigBang (Gamov made a fine tunning of this theory)

By other hand, Hubble's theory give a formula to evaluate the age of universe by

$v = H \cdot D$ $v=H·D$ where $D$ $D$ is the distance of a Galaxy, $v$ $v$ the velocicty of remoteness and $H$ $H$ is the Hubble constant $H = 75 k m s^{- 1}$ $H=75 kms^-1$

If we take a Galaxy at 1 megaparsec = $30.87 x 10^{18}$ $30.87 x 10^18$ km, then

$\frac{1}{H} = \frac{D}{v} = \frac{30.87 \times 10^{18}}{75} = 4.12 \times 10^{17} s e g = 13 \times 10^{19} y e a r s$ $1/H=D/v=(30.87xx10^18)/75=4.12xx10^17 seg=13xx10^19 years$

Nowadays, the trend is go down the Hubble constant and then, the age of univers is growing in the same proportion
