One оf the eаrlier estimаte оf the Hubble cоnstаnt was 500 km/s/Mpc in early 1900s. In early 2000s, measurements of Hubble constant using Cephied stars yield 72 km/s/Mpc. In recent years, the new methods of using red giant stars has been developed and this new method yields 70 km/s/Mp. If you are to compare the 2 recent values, 72 or 70km.s/Mpc, which estimate will results in greater age of the universe? t = 1/Ho Explain your reasoning in as much details as possible.
