Hubble's constant is used to estimate the age of the universe based on the rate of expansion. If the constant were twice as large, that would mean the universe is expanding at a faster rate than we previously thought, which would mean it has taken less time to expand to its current size. Therefore, our estimate of the expansion age of the universe would be cut in half.
