Abstract:
A biggest challenge for today’s astrophysicist is to solve the mystery of primordial evolution of the universe. This is also known as belongs to Planck’s era. In this stage space-time singularity and inflationary phase all occur when universe was just of the size 10-5m. All this evolution occurs in a tiny fraction of a second. This description is made by joining the cosmological principle of isotropy and homogeneity, the Hubble law, and the Einstein’s field equations of General Relativity in the Big Bang Theory or Standard Cosmological Model (SCM). By solving equation proposed by Albert Einstein in the general relativity the cosmological singularity proposed by Alexander Friedmann explain well the Big Bang model of origin of our universe. The expansion of universe started some 15 billion year ago with Big Bang. The studies of red shift in the spectrum of galaxies in near vicinity suggest the expansion of our universe. The experimental studies of Cosmic Microwave Background (CMB) also suggest that Universe is originated due to Big Bang. Early of the twentieth century some astrophysicist started to propound that how long this expansion will last and what is going to be happened with this universe. There are three different fate of our universe suggested in popular literature which are: Big Rip, Big Freez and Big Crunch. In the present work we proposed solution of Friedmann equations and effect of their parameters on Big Crunch the ultimate fate of our universe.
