dark energy

n.
A hypothetical form of energy that permeates all space and tends to cause the universe to expand by exerting a gravitational repulsion, countering ordinary gravitational attraction. Quintessence and the vacuum energy represented by the cosmological constant are possible forms of dark energy.

dark energy

n
(Astronomy) astronomy unobserved energy whose existence is proposed to account for the observed acceleration in the expansion of the universe
