Multiple Choice
For any object moving uniformly, velocity = distance/time. If so, in the Hubble relationship for the expansion of the universe, V = H0d, what is the significance of the constant 1/H0?
A) It is the inverse of the velocity that the object would have at a standard distance of 10 pc.
B) It represents the average spacing between objects in the universe at the present time.
C) It is merely a constant of proportionality, to allow for the different units of V and d.
D) It represents the time since the expansion began, or the age of the universe, assuming the expansion has been uniform.
