Generalized Einstein – Rosen Bridge Inside Black Holes

We generalize the notion of Einstein-Rosen bridge by defining it as a space-like connection between two universes with regions of asymptotically minkowskian space-time infinities.The corresponding symmetry and asymmetry properties of the generalized Einstein-Rosen bridge are considered at the cases of Reissner-Nordstr öm and Kerr metrics.We elucidate the versatility of intriguing symmetry and asymmetry phenomena outside and inside black holes.For description of the test particle (planet and photon) motion it is used the Kerr-Newman metric of the rotating and electrically charged black hole.In particular, it is demonstrated the symmetry and asymmetry of the one-way Einstein-Rosen bridge inside black hole toward and through the plethora of endless and infinite universes.
