Here we go again being patronized by the "nude Emperor" . . .Well, I would suggest that you learn what Einstein's equations say and how the CC relates to them. In essence, it is an energy density of space itself and provides a negative pressure proportional to the density.
"an energy density of space itself" is just another ad hoc invention in order to "explain" the false measurement method which provides crazy motions in the Universe.
