Expert Solution
Concept and Principle:
  • As per Hubble's law, the universe is expanding. If we assume that the expansion's apparent velocity has been constant, we can estimate the time the expansion was happening.

 

  • This gives us the age of the universe and can be derived from Hubble's law. This time also known as Hubble's time is given by,

τH=1H0

Here H0 is the Hubble's constant.
