"Based on the exact solution of the Einstein - Maxwell equations for a centrally symmetric free electromagnetic field and a dusty substance, gravitational models of a proton, electron and neutron are proposed in the form of pulsating unclosed wormholes with two static throats - oppositely charged electric charges that extend into two parallel asymptotically flat vacuum spaces"
we have got two parallel symmetrical worlds or, assuming wormholes with non-parallel axes, we have got two parallel asymmetric worlds.
Maybe Wolfgang Pauli had in mind when wrote to Werner Heisenberg about bifurcation and reduction of symmetry (1958)
