In this paper an attempt is made to understand the basic unified concepts of gravity, electromagnetism, nuclear charge radius, cosmic geometry; cosmic mass density, cosmic thermal energy density and cosmic red shift. The four key assumptions are : 1) Planckâ€™s constant increases with cosmic time. 2) Being a primordial evolving black hole and angular velocity being Ht universe is always rotating with light, speed. 3) Atomic gravitational constant is squared Avogadro number times the classical gravitational constant and 4) Avogadro number is discrete and hence the atomic gravitational constant is discrete. This may be the root cause of discrete nature of revolving electronâ€™s potential energy. Finally it can be suggested that current cosmological changes may be reflected in any existing atom.
