Electromagnetic Accelerating Universe
Paul H. Frampton

TL;DR
This paper proposes that electromagnetic effects of supermassive primordial black holes could explain the universe's accelerated expansion, extending dark matter theories to include charged black holes with significant electromagnetic influence.
Contribution
It introduces a novel hypothesis that electromagnetic repulsion from charged primordial black holes at extreme masses may drive cosmic acceleration.
Findings
Coulomb repulsion can surpass gravity for black holes over a trillion solar masses.
Electromagnetic properties of dark matter may contribute to cosmic acceleration.
Extends dark matter models to include highly charged, supermassive black holes.
Abstract
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.
