Physicists Find Possible Errors In 100-Year-Old Model of the Universe

A trio of preprint papers suggests the universe may not be perfectly uniform on the largest scales, finding tentative 2-to-4-sigma deviations from a core assumption of standard cosmology known as FLRW geometry. Live Science reports: The work combines observations of distant exploding stars and large-scale galaxy surveys to probe whether the universe truly follows a nearly 100-year-old mathematical framework known as Friedmann-Lemaitre-Robertson-Walker (FLRW) cosmology. The analyses revealed mild-but-intriguing deviations from the predictions of the standard model. “We saw a surprising…
