Three possibilities for the nature of dark energy
1) it is an inherent property of empty space, a uniform distribution of energy associated with space itself, called vacuum energy.
2) a slightly different kind of vacuum energy which varies across time and space, called quintessence.
3) it is a modification of the laws of gravity and general relativity we do not yet understand; something beyond Einstein's theory.
