Three New Analyses Are Challenging a Core Assumption of Cosmology
A set of preprints described by New Scientist suggests the universe may be less homogeneous on the largest scales than standard cosmology assumes, potentially opening a path toward resolving some long-running puzzles.

- Three preprints challenge the assumption that the universe is homogeneous and isotropic on very large scales.
- A new test uses supernova and matter-density observations and should return zero if FLRW holds.
