Question

In 2013, the value of the Hubble constant Ho determined by the results from the Planck satellite mission, was 67.8 km/s/Mpc. Using this value, the age of the Universe can be estimated to be approximately 14.5 billion years. If the value of Ho was 60 km/s/Mpc instead of 67.8 km/s/Mpc, how would that affect the estimated age of the Universe? It is impossible to tell without more O information The estimate for the age of the Universe would be more than 14.5 billion years old. The estimated age of the Universe would not change. The estimate for the age of the Universe would be less than 14.5 billion years old. Planck Satellite The Planck satellite has been used to measure cosmological arameters with great accuracy.

Explanation / Answer

age of uinverse= 1/ Ho

ho = 60 km/s/ Mpc = 60 ( km/s) / ( 3 x 10^19 km) = 20 x 10^-19 s^-1

1/H = 1/ (  20 x 10^-19) = 10^19/ 20 = 5 x 10^17 = 15.8 billion years apprx

option b
