Recently, it was shown in [1] that black holes are the source of dark energy.In [2-5], the truth or falsity of this concept has been discussed. We brieflystate the arguments raised in each of these papers, but our main goal is not toaccept or reject these debates. Rather, in this note, we show that black holesin specific structures, such as the Reissner-Nordstrom (R-N) black hole in thepresence of quintessence, string cloud, and perfect fluid, can produce arepulsive force with respect to the weak gravity conjecture mechanism thatovercomes the gravitational force.\textit{ We discuss these repulsions forcesin a population of black holes of the same family can be considered as anauxiliary factor (albeit a weak factor) for the expansion of the universe}.

Can black holes cause cosmic expansion?
