The statement that best describes the movement of galaxies in the universe is:

1. Galaxies are moving away from each other, with galaxies farther away moving faster.

This observation is a key aspect of Hubble's Law, which states that the recession velocity of a galaxy (its speed moving away from us) is proportional to its distance from us.
