  We have found that the hierarchial problems appearing in cosmology is a
manifestation of the quantum nature of the universe. The universe is still
described by the same formulae that once hold at Planck's time. The universe is
found to be governed by the Machian equation, $G M=Rc^2$, where $M$ and $R$ are
mass and radius of the universe. A Planck's constant for different cosmic
scales is provided. The status of the universe at different stages is shown to
be described in terms of the fundamental constants (eg. \textcolor{blue}{$c,
\hbar, G, \Lambda, H$}) only. The concept of maximal (minimal) acceleration,
power, temperature, etc., is introduced and justified. The electromagnetic
interactions are shown to be active at a cosmic level. Their contribution would
exclude the inclusion of dark energy in cosmology.
