Because of the expansion of space, astronomers see all distant galaxies moving away from Earth, with more distant galaxies moving faster. An observer in one of these distant galaxies would see all galaxies
A) moving toward the observer, with more distant galaxies moving faster.
B) moving away from the observer, with closer galaxies moving faster.
C) moving away from the observer, with more distant galaxies moving faster.
D) on one side of the observer moving toward the observer and all galaxies on the other side moving away from the observer, with more distant galaxies moving faster.

The expansion of space causes all galaxies to move away from each other. An observer in any galaxy would see other galaxies moving away, with more distant galaxies moving faster, due to the uniform expansion of the universe. This is consistent with Hubble's law, which states that the velocity at which a galaxy moves away from us is proportional to its distance from us.
