What tells Gravity on the shape and size of an electron

TL;DR

This paper explores how the gravitational field of an electron, modeled by the Kerr-Newman metric, implies a ring-shaped singularity at the Compton radius, suggesting a bubble-like source with a Higgs field inside.

Contribution

It proposes a novel model of the electron's gravitational field as a rotating vacuum bubble bounded by a string, incorporating a Higgs field in a false vacuum state.

Findings

Electron's gravitational field modeled by Kerr-Newman metric with a ring singularity.

The singularity is regulated by a bubble-like source with a Higgs field.

The model suggests a relativistically rotating, bubble-shaped electron structure.

Abstract

Gravitational field of an electron, fixed by experimental values of its mass, spin, charge and magnetic moment, is given by the metric of Kerr-Newman (KN) solution. Unexpectedly, this metric contains a singular ring of the Compton radius, which should be regulated resulting in a weeak and smooth source. The consistent source takes the form of an oblate vacuum bubble, bounded by a closed string of the Compton radius. The bubble turns out to be relativistically rotating and should be filled by a coherently oscillating Higgs field in a false vacuum state.
