Definitions for "Dark energy"
A poorly understood (and non-luminous) substance that exerts a pressure that tends to accelerate the expansion of the universe. This dark energy counteracts gravity's natural tendency to slow the expansion of the universe. It is particularly important to understand this substance, as it appears to make up the majority of our universe. Dark energy is also often referred to as the "cosmological constant". It is distinct from dark matter, which gravitates in the same way as ordinary matter, but is not luminous.
the residual energy in empty space that is causing the expansion of the Universe to accelerate. Einstein's Cosmological Constant was a special form of dark energy.
A hypothetical type of energy that fills the empty space. Together with dark matter they form about 75% of the matter/energy of the universe.
