How is Hubble's constant related to time?

Answer 1

[Hubble's costant] = #T^(-1)#

The reciprocal of the Hubble constant #H_0# expressed in km/sec/mega parsec is used ro approximate the age of our universe as 13.8 billion years. The dimension# [H_0] = T^(-1)#.

Given that both km and megaparsec are very small and very large units of distance, it should be noted that the dimension of [km/megaparsec= 0 (dimensionless)].

The Hubble time is the reciprocal of the Hubble constant and provides an estimate of the universe's age by showing how long it has been expanding at its current rate. This is how Hubble's constant is related to time.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
