In physical cosmology, astronomy and celestial mechanics, dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe. The indication that the universe is expanding at an accelerating rate is the most accepted theory to explain observations since the 1990s. Dark energy’s existence is needed to reconcile the measured geometry of space with the total amount of matter in the universe. An accepted estimate is that the universe is made up of 74% dark energy, 22% dark matter and 4% ordinary matter.
