Lightning starts with a positive fast discharge, followed by an even faster and more extensive negative discharge observed in 3D; signal polarizations slant from the discharge propagation direction and rotate between the two opposite fast discharges; these features can only be due to a cosmic-ray shower that preconditioned the discharge path and guided the discharge current direction.

Planck’s law ignores but does not prohibit black-body radiation (BBR) from being circularly polarized. BBR from nanostructured filaments with twisted geometry from nanocarbon or metal has strong ellipticity from 500 to 3000 nanometers. The submicrometer-scale chirality of these filaments satisfies the dimensionality requirements imposed by fluctuation-dissipation theorem and requires symmetry breaking in absorptivity and emissivity according to Kirchhoff’s law. The resulting BBR shows emission anisotropy and brightness exceeding those of conventional chiral photon emitters by factors of 10 to 100. Image credit: Lu et al., doi: 10.1126/science.adq4068.
