Electromagnetic accelerating universe

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 holographic entropy bound saturated. Astrophysicists recently suggested PBHs are formed with electric charges Q, retain their for age universe, all same sign, Q/M increases mass M. Adopting these assumptions using approximate formula relating Q M, it here that, over a trillion solar masses, Coulomb repulsion can exceed gravitational attraction electromagnetic properties possible cause observed accelerated cosmological expansion.
