If the Hubble constant is 73 km/s/Mpc then the age of the universe is 13.4 billion years, assuming a uniform expansion. Suppose it were discovered that the Hubble constant is actually larger than 73 km/s/Mpc. What effect would this have on the calculated age of the universe?
A)Without another factor, the average mass density of the universe, the age of the universe cannot be estimated from this information.
B)It would decrease the calculated age of the universe.
C)Because the Hubble constant simply relates galaxy motion to its distance from our galaxy, it has no connection with the age of the universe.
D)It would increase the calculated age of the universe.

A larger Hubble constant implies a faster rate of expansion, which means the universe would have taken less time to reach its current size, thus decreasing the calculated age of the universe.
