Please can somebody explain how the age of the universe can be determined using Hubbles Constant?
If the constant is taken as 10km/s (just for the sake of easiness), how can this be figured out using calculations?
the current value of Hubble constant is 71km/s/Mpc,now if you want to calculate the Hubble time, that is the time that have passed since Big bang, you do:
T=10^{12}/H
where H is the Hubble constant, the result gives the Hubble time in years. If I put 71 in H, if gives 14 billion of years
From the formula you can see that the Hubble constant diminish in value with time, as the Hubble time augments
