Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s ...

Multiple independent analyses of the oldest light in the universe now point to a subtle but persistent twist in its polarization, a signal that, if confirmed, cannot be explained by the Standard Model ...
