Universe's Expansion Is Now Slowing Down
A recent study suggests that the universe's expansion is slowing down rather than accelerating, challenging the standard cosmological model and implying potential new physics or models like a cyclic universe. The findings focus on the impact of progenitor star age on Type Ia supernova luminosity, which could bias previous measurements of cosmic expansion. While intriguing, the results are met with cautious skepticism and require further validation with upcoming data.
