As light travelled through the universe, it interacted with dark matter and dark energy and may have caused the plane of polarisation to rotate. “If dark matter or dark energy interact with the light of the cosmic microwave background in a way that violates parity symmetry, we can find its signature in the polarization data,” said Yuto Minami, a postdoctoral fellow at IPNS. The scientists found that the distance travelled by light from dust within the Milky Way galaxy is shorter than that of the ancient light, meaning that it is not affected by either dark matter or dark energy.
