Calculating the CMB Temperature*

A theoretical model estimates a temperature of 2.70K for the CMB, compared to the experimental value of 2.73K. It is based on a General Relativity metric, which was derived to be applicable to the electrical interaction as well as to the gravitational. It is applied to the Bohr model of hydrogen, wherein the electron mass is modified due to the electron-proton interaction. The ionization energy of hydrogen is proportional to the electron mass, so it is thereby split into three closely spaced levels, with energy differences in the microwave region. Specifically, hydrogen emits 1.71 mm microwaves at a temperature of 5.58 K. When extended to the first ionization of nine other atoms, they emit microwaves in the range of 2 to 6 Kelvin. Helium is an exception, emitting 0.582 mm at 16.4 K. The metals emit microwaves below 2 Kelvin. For example, iron emits 5.07 mm microwaves at 1.88 Kelvin. Hypothetically, if the low Kelvin atoms were a mixture of two parts hydrogen to seven parts iron, the average temperature would be 2.70K. Thus, it seems feasible that the CMB temperature of 2.73K could be due to the as yet unknown distribution of low Kelvin atoms emitting microwaves in inter-galactic space. Currently, there is no evidence that low Kelvin atoms emit microwaves.
