Noun

(uncountable)

(astronomy, astrophysics) A hypothetical form of energy which, it is supposed, is spread uniformly throughout space (time) and has anti-gravitational properties: it represents a possible mechanism for the cosmological constant, and thus is one of the possible explanations for the current accelerating rate of expansion of the universe; and it is estimated to account for about 74% of the mass-energy of the universe.
