Suppose new experimental evidence were to point to a Hubble constant value of H₀ = 50 km/s/Mpc. A calculation of the age of the universe using this value would give A) the same value now calculated, namely 13.4 billion years. B) an age younger than 13.4 billion years. C) an age older than 13.4 billion years. D) a different value of the age, but more information is needed to estimate what it would be.

The Hubble constant (H0) is inversely proportional to the age of the universe. A lower value of H0 implies a larger age for the universe. Therefore, if the Hubble constant were found to be 50 km/s/Mpc, this would suggest an age older than the currently estimated 13.4 billion years.
