a hypothetical form of energy whose negative pressure counteracts gravity and is assumed to be responsible for the universe expanding at an accelerating rate.
The Deep Web Vs. The Dark WebDeep web and dark web are so technical in nature that we came across a lot of confusion as to what they actually mean in our research. More tech-savvy publications generally have a disclaimer when discussing the dark web, pleading with their readers that this is not to be confused with the deep web, which is related, but not at all the same thing. So, what exactly are the dark web and the deep web, and why are technology reporters so wary when using either term?

Science definitions for 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.
