Is the Universe Slowing Down? New Study Challenges Dark Energy Theory

A new study from Yonsei University challenges the long-accepted view that the universe’s expansion is accelerating. Researchers found that biases in type Ia supernova data—linked to the age of their progenitor stars—may have led scientists to overestimate dark energy’s effect.When corrected, the data suggests the universe’s expansion is slowing, not speeding up, marking a potential paradigm shift in cosmology.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
