Abstract:

A contracting universe, for parameter k = +1   in   Robertson   Walker   metric   at   very   high temperatures close to the singularity is modelled as a  highly  dense  assembly  of  photons. We  use  the black  body  approximation  for  assembly  of  photons to  show  that  available  photon  states  in  the  phase space are completely filled up at temperature TS = (5.52).  1025K.    When  the  temperature  increases beyond   TS,   the   system   transforms   to   a   highly unstable,  superheated,  non - equilibrium  state, and leads to  the  inflation  of  space - time and  the  big bang.
