Webknown as cosmic birefringence because it is as if space itself behaved like a birefringent crys-tal (Komatsu , 2024). Emitted at the epoch of recombination and with its polarization angular power spectra ac-curately predicted by the standard cosmologi-cal model, the cosmic microwave background (CMB) is the ideal tool to measure birefrin-gence. 2.
