Suppose the Hubble constant turned out to be 130 km/sec/Mpc and not 65 km/sec/Mpc. How would that affect our estimate of the age of the Universe?
A) The Universe would be about 30 billion yrs old.
B) The Universe would be about 7 billion yrs old.
C) The Universe would be about 130 billion yrs old.
D) It would have no effect on our estimates of the Universe's age.
E) None of these choices is correct.

A higher Hubble constant implies a faster rate of expansion, leading to a younger estimated age for the Universe. Doubling the Hubble constant from 65 to 130 km/sec/Mpc would roughly halve the estimated age, making it about 7 billion years.
