## Resource

Could the universe be slowing down rather than accelerating? A new study from Yonsei University challenges the standard picture of cosmic expansion, arguing that age-related biases in Type Ia supernovae may have distorted previous conclusions. The findings add fuel to the growing debate over dark energy and the evolution of the universe, while proposing a new way to test the competing explanations.
