  The initial cosmological singularity in the framework of the general theory
of relativity is resolved by introducing the effect of the uncertainty
principle of quantum theory without violating conventional laws of physics. A
plausible account of the mechanism of the big bang, analogous to that of a
nuclear explosion, is given and the currently accepted Planck temperature of
about 10^(32)K at the beginning of the big bang is predicted.
  Subj-class: cosmology: theory-pre-big bang; mechanism of the big bang.
