The interpretation of the CMBR

Yi-Jia Zheng

Abstract

t In the popular ΛCDM model, the cosmic microwave background radiation (CMBR) is thought to be the remnant of the early hot universe. An important precondition of this interpretation of CMBR is: after the last scattering surface formed, the high temperature ionized gases in the universe became low temperature neutral gases and so the universe has been completely transparent to the radiation which comes from the hot early universe. However, observations show that today most gases in the universe are still in a high temperature ionized state. The universe is not completely transparent to the radiation which comes from the hot early universe. According to the famous Sunyaev-Zeldovich effect, if the CMBR comes from the early hot universe and follows a perfect blackbody spectrum, the free electrons in the cosmic plasma will distort the perfect blackbody spectrum of the CMBR. In this case, the observed CMBR cannot be of a perfect blackbody spectrum. This is a fatal flaw in the interpretation of CMBR using the ΛCDM model. In order to overcome this fatal flaw, in this paper it is proposed that in the ΛCDM model frame, a better interpretation of CMBR is: The CMBR is a thermal equilibrium product between the high temperature ionized gases and the cosmic radiation field in the local universe space.
