The presently accepted value of the Hubble constant gives an age of:
A)4.5 billion years.
B)8-9 billion years.
C)14 billion years.
D)18 billion years.
E)22 billion years.

Question

Quizplus · Accepted Answer

The presently accepted value of the Hubble constant is approximately 70 km/s/Mpc. Using this value, the age of the universe can be estimated using the equation T = 1/H0, where T is the age of the universe and H0 is the Hubble constant in units of km/s/Mpc. Substituting in the given value of H0, we get T = 1/70 km/s/Mpc = approximately 14 billion years. Therefore, the best choice is C, 14 billion years. The presently accepted value of the Hubble constant is around 70 km/s/Mpc, which corresponds to an age of the universe of approximately 14 billion years.
