The age of universe can also be determined by working out the Hubble's constant which is nothing but the current expansion rate of universe.

Once the Hubble's constant is worked out, the age of universe can be calculated by following mathematical relation

Age of Universe= $\frac{2}{3H_{0}}$

where , $H_{0} =$ Hubble's constant
