On a dark summer night in the northern hemisphere, we can see the Milky Way, but we can't see the center of the Milky Way. Why not?
 
  A) Interstellar dust and gas absorb and scatter visible light.
  B) We are in the center of the Milky Way.
  C) There are no stars in the center of the Milky Way, just a supermassive black hole.
  D) The center of the Milky Way does not emit enough visible light.

Question 2

How does Hubble's law relate cosmological redshift to distance?
 
  What will be an ideal response?

Answer to Question 1

A

Answer to Question 2

The redshift corresponds to recessional velocity and, according to Hubble's Law, the greater the redshift, the greater the velocity. The greater the velocity, the more distant the galaxy is.
