Question

theories about the universe quick check
which statement best describes the movement of galaxies in the universe? (1 point)
○ galaxies are moving away from each other, with closer galaxies moving faster.
○ galaxies are moving toward each other, with galaxies farther away moving faster.
○ galaxies are moving toward each other, with closer galaxies moving faster.
○ galaxies are moving away from each other, with galaxies farther away moving faster.

Explanation:

The expansion of the universe (supported by evidence like Hubble's law) shows galaxies move away from each other. Hubble's law states that the velocity of a galaxy moving away is proportional to its distance—farther galaxies move faster. So we analyze each option:

• First option: Closer galaxies moving faster is wrong (should be farther).
• Second/Third options: Galaxies moving toward each other is wrong (universe expands, so they move apart).
• Fourth option: Matches the expansion and Hubble's law (galaxies move away, farther ones faster).

Answer:

D. Galaxies are moving away from each other, with galaxies farther away moving faster. (Assuming the last option is D; if options are labeled differently, adjust the identifier but keep the text. If no labels, state "The last option: Galaxies are moving away from each other, with galaxies farther away moving faster.")
