Explanation:
Detailed explanation-1: -Yes, gravity can slow down the expansion of the universe. That’s why if the universe’s average density is greater than critical, it is forecast to collapse into a big crunch (see this section of the Wikipedia article on the Friedmann equations).
Detailed explanation-2: -Gravity pulls galaxies closer together; dark energy pushes them apart. Whether the universe is expanding or contracting depends on which force dominates, gravity or dark energy. Just after the Big Bang, the universe was much smaller and composed of an extremely high-energy plasma.
