Multiple Choice
For any object moving uniformly,velocity = distance/time.So in the Hubble relationship for the expansion of the universe,v = H₀r,what is the significance of the constant 1/H₀?
A) The Hubble constant represents the average spacing between objects in the universe at the present time.
B) The Hubble constant represents the time since the expansion began, or the age of the universe.
C) The Hubble constant is merely a constant of proportionality to allow for the different units in v and r.
D) The Hubble constant is the inverse of the velocity that the object would have at a standard distance of 10 parsecs.
