there is a theory that gravity could pull galaxies back together, causing a reverse big bang. which observation makes this theory less likely than the idea that the universe may continue to expand? background radiation is present. galaxies exist outside of the milky way. the expansion of the universe is accelerating. gas giants form farther from the sun, where temperatures are cooler.

Answer

Brief Explanations:

The accelerating expansion of the universe implies a force counter - acting gravity's pull. If the expansion is accelerating, it is less likely that gravity will pull galaxies back together for a reverse big bang. Background radiation is evidence of the big bang but not related to the future of expansion. Galaxies outside the Milky Way just show the vastness of the universe. Gas giant formation is about planetary formation in our solar system and not relevant to the universe's overall expansion or contraction.

Answer:

The expansion of the universe is accelerating.
