Dark energy. Conceptual computer artwork of quintessence,a hypothetical form of dark energy that is thought to be driving the universe's expansion at an accelerating rate. Dark energy accounts for 70% of the total mass-energy of the universe and there are two proposed forms: the cosmological constant and quintessence. The cosmological constant fills space homogeneously whereas with quintessence,energy can vary in time and space | |
