The new study, based on Dark Energy Survey (DES) and DESI data, proposes a hybrid axion dark energy model that forecasts cosmic collapse much sooner than previously estimated.
Researchers found that dark energy's influence may be changing over time, potentially reversing expansion and causing all matter to collapse back into a dense state.
This challenges the long-held belief in an ever-expanding universe, but the model requires further verification and more data to confirm its predictions about the universe's ultimate fate.
