什么是 dark energy？

Particle physicist Don Lincoln states: the near-total absence of antimatter in the universe remains unsolved; dark energy drives cosmic acceleration but its nature is unknown; a Theory of Everything may exist yet remains far from experimental verification; while the Standard Model is complete, it fails to explain gravity or dark matter, and scientific progress hinges on testable predictions—not mathematical elegance.
