dark energy

   Also found in: Acronyms, Encyclopedia, Wikipedia 0.01 sec.
dark energy
A form of energy hypothesized to reside in the structure of space itself, responsible for the accelerating expansion of the universe. Dark energy theoretically counterbalances the kinetic energy of the universe's expansion, entailing that that the universe has no inherent curvature, as astronomical observations currently suggest. Dark energy appears to account for 73 percent of all the energy and matter in the universe. See also big bang.

These measurements of the cosmic microwave background-a faintly glowing relic of the hot, dense, young universe-put limits on proposed alternatives to the standard model of cosmology and provide further support for the standard cosmological model, confirming that dark matter and dark energy make up 95 percent of everything in existence, while ordinary matter makes up just 5 percent.
One of the deepest mysteries in all of physics and astronomy, the nature of dark energy determines the fate of the universe.
If you are experiencing a lot of fear, self-doubt and confusion, you can be pretty sure there will be dark energy around.
