Final answer:

Dark energy drives the acceleration of the universe's expansion, making space less dense over time.


Explanation:

Dark energy is the main reason why most of the universe is "pretty empty." This mysterious energy pushes spacetime apart, causing the acceleration of the universe's expansion. Unlike gravity, which pulls objects together, dark energy acts as a repulsive force, leading to the universe becoming increasingly sparse over time.
