SUPREME THEORY OF EVERYTHING: Theoretical Formulation of The Spectral Density of Electromagnetic Radiation Emitted By A Nonblack Body
Hertzsprung-Russel Diagram (HRD) plots each star on a graph measuring the star’s brightness concerning its temperature (color) between 2000K and 50000 K. It registered about 90 percent of the stars in the universe, including the Sun, located in the main sequence branch of stars in HRD. HRD is an experimental diagram, and its theory could be supposed to be Planck's law. However, Planck's law itself is empirical and contradicts recorded astronomical experimental data. Modern astronomy can observe celestial bodies in space, with surface temperatures ranging from 0 Kelvin to millions of degrees. During this time either Planck's law or HRD didn't develop. In this paper, the spectral density of electromagnetic radiation of non-black bodies is described theoretically.
