Question

There is a theory that gravity Eould 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 1

Answer: The expansion of the universe is accelerating

Explanation: Edge test

Answer 2

Step-by-step explanation:

The correct answer is derived from Hubble's observation that galaxies that are further away from the sun are moving away from our sun at a rate that is greater than those that are close by.

This observation suggests that our universe is expanding.

Now which choice best fits this observation? I don't know that this answer is correct, but it might be the closest choice. Galaxies exist outside the Milky Way, but that answer does not take into account their motion which is a necessary part of the theory.
