Scientists just dropped the sharpest look yet at the universe’s dark energy—the mysterious force making space expand faster and faster. After six years and 669 million galaxies, they combined four different ways of studying the cosmos for the first time ever. The result? We’re closer than ever to cracking what’s driving most of the universe, but there’s still a cosmic puzzle: galaxies aren’t clustering like our models predict. Next up: even more galaxies and, hopefully, answers! #Science #DarkEnergy #SpaceMystery
