In the framework of Multiple Point Principle (MPP), where the existence of the two degenerate vacua of the Universe, the first, ElectroWeak vacuum with ≈ 246 GeV (“true vacuum”), and the second at Planck scale ∼ 10 18 GeV (“false vacuum”); we investigated the gravitational black-hole-hedgehog's solution with magnetic field contribution in the GraviWeak unification model described by f ( R ) gravity. We have considered the phase transition from the “false vacuum” to the “true vacuum” and confirmed the stability of the ElectroWeak vacuum. The “false vacuum” defect configurations for the black-hole-hedgehog have given a global monopole and this monopole has been “swallowed” by the black-hole with core mass M BH ≈ 3.65 × 10 18 GeV and radius δ ≈ 6 × 10 −21 GeV −1 . The horizon radius of the black-hole-hedgehog is around r h ≈ 1.14 δ .
