Electron (proton) – pulsating or a stationary object?

We investigate the creation of an electron (proton) as a perturbation of space. We use the Robertson-Walker metrics to describe the origin of electron (proton) mass. We compute the radii of the electron and the proton in curved and flat spaces with torsion. We show that an electron lives in flat space with torsion, and a proton lives in curved space with torsion.
