Is the universe really eternal? New research suggests it may not be. Astronomers studying data from the Dark Energy Survey (DES) and the Dark Energy Spectroscopic Instrument (DESI) have found signs that dark energy, the mysterious force driving cosmic expansion—might not be constant after all. If true, this means our universe won’t expand forever, but could slow down, reverse, and collapse in a cataclysmic Big Crunch in about 33 billion years.
