Abstract

In a quantum gravitational approach, from the beginning of cosmic evolution, the authors assumed the existence of hot primordial evolving black holes. During the evolution of primordial black holes, decreasing thermal energy density is supposed to be directly proportional to their decreasing mass-energy density. When mass of the assumed evolving black hole approaches sin^-2(θ_w) times the Chandrasekhar’s mass limit, density of the evolving black hole seems to approach the order of nuclear mass density. If primordial universe is responsible for generating large number of primordial evolving black holes, then the whole universe can certainly be assumed to be a big primordial evolving black hole. By considering the current universe as an ‘evolved’ primordial black hole of isotropic temperature equal to the 2.725 K, in a quantum gravitational approach its current Hubble constant can be fitted very easily. In reality one may or may not be able to reach a black hole. By considering the whole “observable universe” as a huge primordial evolved black hole, many interesting solutions (including magnetic monopole problem) will come into visualization.
