From the 1970s to the present, the accepted value of H has almost doubled, so:
A)the age of the universe is twice as old as we originally believed.
B)the age of the universe is half what we believed.
C)the Copernican principle is not valid beyond our solar system.
D)the ages of the oldest globular clusters are invalid.
E)the critical density must also be halved.

Question

Quizplus · Accepted Answer

The Hubble Constant (H) is used to estimate the age of the universe, with a higher value indicating a younger age. Since the accepted value of H has almost doubled, it means that the age of the universe would be half of what was initially believed. The Hubble constant (H) is used to estimate the age of the universe based on the expansion rate of the universe. As H has almost doubled from its originally accepted value, this means the estimated age of the universe has decreased by half. Therefore, the best choice is B- the age of the universe is half what we believed.
