If the Hubble constant is 75 km/s/Mpc, then the age of the universe is 13 billion years. Suppose it were discovered that the Hubble constant is actually larger than 75 km/s/Mpc. What effect would this fact have on the estimated age of the universe?
A) The estimated age could be increased or decreased, depending on the recession velocity of the galaxy being investigated.
B) The estimated age would be the same.
C) The estimated age would be decreased.
D) The estimated age would be increased.
