Possible nonequilibrium imprint in the cosmic background at low frequencies
Cosmic background radiation has been observed to deviate from the Planck law expected from a blackbody at ∼2.7 K at frequencies below ∼3 GHz. We discuss the abundance of the low-energy photons from the perspective of nonequilibrium statistical mechanics. We propose a mechanism of stochastic frequenc...
