Answer:

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·D# where #D# is the distance of a Galaxy, #v# the velocicty of remoteness and #H# is the Hubble constant #H=75 kms^-1#

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

#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
