Abstract
A Kerr nonlinear blackbody (KNB) is a new kind of blackbody in which bare photons with opposite wave vectors and helicities are bound into pairs and unpaired photons are transformed into nonpolaritons. In the present paper, the radiation of a KNB is considered from the viewpoint of an observer in arbitrary uniform motion with respect to a rest frame of reference of the radiation. It is found that the radiation laws, which include the distribution of nonpolaritons and so forth, are modified due to the motion. Moreover, under a special condition, we notice that the only effect of the motion is to introduce an angle-dependent directional temperature, which replaces the rest-frame temperature of the cavity. Besides, we try to extend the model of a KNB to the whole Universe and apply the modified radiation laws to the question of 2.7 K cosmic microwave background radiation (CMBR).
