Quizplus · Accepted Answer

The age of the universe can be estimated by taking the inverse of the Hubble constant. The Hubble constant (H₀) is given as 90 km/s/Mpc. To find the age of the universe in years, we first convert the Hubble constant to the appropriate units. The conversion factor is 1 Mpc = 3.09 x 10^19 km and 1 year = 3.15 x 10^7 s. Thus, the age of the universe in years is approximately 1/H₀ = 1 / (90 km/s/Mpc * (1 Mpc / 3.09 x 10^19 km) * (3.15 x 10^7 s / 1 year)) ≈ 11 billion years.
