摘要：
In recent work we have extended the theory that dark matter is composed of primordial black hole (PBHs) to extremely high masses and made an assumption that the holographic entropy bound is saturated. Astrophysicists have recently suggested that PBHs are formed with electric charges Q, retain their charges for the age of the universe, all charges have the same sign, and Q/M increases with mass M. Adopting these assumptions and using an approximate formula relating Q and M, it is here suggested that, for PBHs with over a trillion solar masses, Coulomb repulsion can exceed gravitational attraction and that electromagnetic properties of dark matter are a possible cause for the observed accelerated cosmological expansion.
