Dark energy behaves strangely: in the past it was stronger than it is now. It's like an illusion caused by an open door: the sound seems louder, but the speaker is at the same volume. The new KMIX model reveals this trick.

🎯 The term 'quintessence' for dynamic dark energy models comes from ancient philosophy, where it referred to a fifth element filling the heavens — distinct from earth, water, air, and fire.
