Kind: research · Impact: low

## In brief

- A Physics News article reports that the matter-antimatter asymmetry still provides no evidence of new physics.
- Known matter-antimatter differences do not account for the scale of the universe's matter dominance.
- The source leaves open the possibility that unknown physics is responsible for the imbalance.

## Why it matters

It clarifies the status of one of cosmology's major open questions, showing that known CP violation falls short of explaining the observed matter excess.
