As if dark energy weren't already mysterious and baffling enough, new research suggests that this unknown force may not be driving galaxies apart at an accelerating rate anymore.
This remarkable result comes from research that suggests that the expansion of the universe has already begun to slow, contrary to the currently favored belief that dark energy is still accelerating the expansion of the cosmos. The discovery also follows results from the Dark Energy Spectroscopic Instrument (DESI) that last year indicated that dark energy is weakening.
