The universe is expanding, and the rate of expansion is accelerating. The discovery of dark energy was made in the 1990’s and was surprising to astronomers, who expected to find that the cosmic expansion would slow down as gravity pulls the matter in the universe back in on itself, much as a ball thrown in the air would eventually reverse course and fall to the ground.
