The uncanny resemblance of the global distribution of all experimentally known atomic spectral lines to the Planckian spectral distribution associated with black body radiation at a temperature of is reported. This value coincides with the critical temperature of equilibrium between the respective densities of radiation and matter in the early universe.
The global distribution of all experimentally known atomic spectral lines shows an uncanny resemblance to the Planckian spectral distribution associated with black body radiation at a temperature of T = 9000 K, as shown by Alexander Szameit and co‐workers in article number 2000033. This value coincides with the critical temperature of equilibrium between the respective densities of radiation and matter...
