A research team has developed a method to reduce uncertainties in measurements of cosmic birefringence, a subtle rotation in the polarization of the cosmic microwave background that may hold clues to new physics beyond the standard model. The work, published January 27 in Physical Review Letters, provides the first quantitative treatment of uncertainty in the birefringence angle, a key observabl
