Product of ¡®Hubble volume¡¯ and ¡®cosmic critical density¡¯ can be called as the ¡°Hubble mass¡±. The three key assumptions are: 1) within the Hubble volume, each and every point in free space is influenced by the Hubble mass, 2) ¡®molar electron mass¡¯ can be considered as the rest mass of a new heavy charged elementary particle and 3) atomic gravitational constant seems to be Avogadro number times the classical gravitational constant. This is a new approach and may be given a chance in understanding the four fundamental cosmological interactions. %K Hubble Volume %K Critical Density %K Hubble Mass %K Coulomb Mass %K Molar Electron Mass %K Atomic Gravitational Constant and the CMBR Temperature %U http://article.sapub.org/10.5923.j.astronomy.20120105.05.html
