Avoidance of Schwinger Mechanism in Electromagnetically Accelerating Universe

TL;DR

This paper discusses how the Electromagnetically Accelerating Universe model avoids the Schwinger pair production mechanism, which would otherwise discharge primordial massive singularities and affect cosmic acceleration.

Contribution

It introduces constraints on charges and masses of primordial singularities to prevent Schwinger pair production in the EAU model.

Findings

Electric fields in EAU are constrained to prevent vacuum discharge.

Schwinger mechanism is avoided in EAU by charge-mass constraints.

Implications for stability of primordial singularities.

Abstract

In quantum electrodynamics, Schwinger showed in 1951 that in a uniform electric field the vacuum may spontaneously produce electron-positron pairs. For this to occur, the required electric field is exceptionally large, $\sim 10^{18}$ N/C. In the Electromagnetically Accelerating Universe (EAU) model, such an electric field would be undesirable because it discharges the Primoridal Extemely Massive Naked Singularities (PEMNSs) whose mutual repulsion causes the acceleration. This leads to a constraints on the charges and masses of the PEMNSs which must be satisfied in an EAU model.
