Evidence that the universe is expanding is best provided by the ________.

• spiral shape of the Milky Way galaxy
• red shift in the light from distant galaxies
• change in the swing direction of a Foucault pendulum
• parallelism of Earth’s axis in orbit

Which galaxy is closer to Earth?

• A is closer because it has a greater shift
• A is closer because it has a smaller shift
• B is not the closer galaxy, it is further
