Question

question 4 of 28 which sentence best describes a role of gravity in the formation of the universe? a. gravity caused background microwave radiation to be emitted as the universe formed. b. gravity caused galaxies to move apart from one another in a symmetrical way. c. gravity caused stars to come together and galaxies to form after the big bang. d. gravity caused the universe to expand from a central point.

Explanation:

After the Big - Bang, gravity played a crucial role in the formation of the universe. It caused matter to clump together. Stars formed as matter aggregated under the influence of gravity, and these stars then came together to form galaxies. Background microwave radiation is a remnant of the early universe and not directly caused by gravity for its emission. Galaxies moving apart is due to the expansion of the universe (cosmological expansion) rather than gravity making them move apart symmetrically. The expansion of the universe from a central point is mainly related to the initial conditions of the Big - Bang and not gravity causing the expansion from a central point.

Answer:

C. Gravity caused stars to come together and galaxies to form after the big bang.
