If the uncertainty in the Hubble constant H₀ = 73 km/s/Mpc is 10%, leading to values of between 65.7 km/s/Mpc and 80.3 km/s/Mpc, what is the corresponding range in the estimated age of the universe? A)1.7 billion years, from 12.2 to 14.9 billion years B)2.8 billion years, from 12.8 to 15.6 billion years C)There is insufficient information to calculate this uncertainty from the given numbers. D)1.4 billion years, from 12.7 to 13.9 billion years

Question

Quizplus · Accepted Answer

The age of the universe is inversely proportional to the Hubble constant. A higher Hubble constant implies a younger universe, and vice versa. Given the range of the Hubble constant from 65.7 to 80.3 km/s/Mpc, the corresponding ages of the universe can be calculated using the inverse relationship, leading to a range of ages that spans approximately 1.7 billion years, from 12.2 to 14.9 billion years.
