In this work, we consider the availability of black holes in the framework of standard cosmology. The density of the black holes as compared to total density of the universe can be evaluated from many astrophysical processes. One of them is the present matter density of the universe. Considering this theory, we have evaluated the upper limit on the initial mass fraction of the black holes in different accretion efficiencies and found quite interesting results. Moreover, we have discussed the results in comparison with Brans-Dicke theory. |
