Galactic Voids as Possible Evidence of Black Hole Evaporation

The Λ-CDM cosmological model currently describes the existence of galactic voids using gravitational clustering and quantum fluctuations from the big bang. This paper proposes a hypothesis that considers black hole evaporation as a contributing factor in the formation and expansion of galactic voids. Hawking radiation expels energy from a black hole, decreasing it's mass. Due to conservation of angular momentum, decreasing the mass of the central body will increase the radius of all orbiting bodies. It was determined that primordial black holes with mass less than 1015g would have evaporated by now, and the observed galactic voids could be the aftermath of the evaporation of primordial black holes.
