  By allowing the light cones to tip over on hypersurfaces according to the
conservation laws of an one-kink in static, Schwarzschild black hole metric, we
show that in the quantum regime there also exist instantons whose finite
imaginary action gives the probability of occurrence of the kink metric
corresponding to single chargeless, nonrotating black hole taking place in
pairs, the holes of each pair being joined on an interior surface, beyond the
horizon.
