Summary:
Astronomers are rethinking one of cosmologyrCOs biggest mysteries: dark energy.
New findings show that evolving dark energy models, tied to ultra-light axion particles,
may better fit the universerCOs expansion history than EinsteinrCOs constant model.
The results suggest dark energyrCOs density could be slowly declining,
altering the fate of the cosmos and fueling excitement that we may be witnessing the universerCOs next great revelation.
