    Universes inside a Λ\Lambda black hole

    Full text link
    We address the question of universes inside a Λ\Lambda black hole which is described by a spherically symmetric globally regular solution to the Einstein equations with a variable cosmological term Λμν\Lambda_{\mu\nu}, asymptotically Λgμν\Lambda g_{\mu\nu} as r0r\to 0 with Λ\Lambda of the scale of symmetry restoration. Global structure of spacetime contains an infinite sequence of black and white holes, vacuum regular cores and asymptotically flat universes. Regular core of a Λ\Lambda white hole models the initial stages of the Universe evolution. In this model it starts from a nonsingular nonsimultaneous big bang, which is followed by a Kasner-type anisotropic expansion. Creation of a mass occurs mostly at the anisotropic stage of quick decay of the initial vacuum energy. We estimate also the probability of quantum birth of baby universes inside a Λ\Lambda black hole due to quantum instability of the de Sitter vacuum.Comment: REVTEX, 9 pages, 13 figures.

    Quantum cosmology with rotation

    No full text
    The rotation of astronomical objects may be of a cosmological origin due to the Universe's specific angular momentum estimates proving to exceed those for spiral galaxies. The problem is expected to be solved in the framework of quantum geometrodynamics. © World Scientific Publishing Company

    Field interpretation of General Relativity

    No full text
    A field interpretation of General Relativity, without resorting to Einstein-Hilbert's equations, has been presented for three cases: a static centrally symmetric gravitational field, radiation of gravitational waves and a homogeneous isotropic cosmological model. The possibility of an effective Riemannian space being used in General relativity should not been ruled out. © 2018 Published under licence by IOP Publishing Ltd

    On gravitational radiation of microsystems

    No full text
    Intensities of the gravitational radiation from a coalescence of miniholes and quadrupole transitions of hydrogen-like atoms are calculated. The total energies of the background gravitational radiation from the coalescence of miniholes and the graviatom quadrupole transitions prove to be comparable with that from the coalescence of two stellar mass black holes. © 2020 World Scientific Publishing Company

    On the Deflection of Light by a Charged Rotating Black Hole

    No full text
    The Kerr-Newman, Schwarzschild, Reissner-Nordstrom, Kerr and Lense-Thirring metrics have been presented. The deflection of light by Kerr-Newman's black hole has been evaluated. Expressions for the law of motion and trajectory of light have been obtained. The black hole is assumed to be slowly rotating. The light impact parameter is considered to be much superior to the gravitational radius and classical radius of the black hole. The deflection of light is both due to attraction by the black hole mass and due to repulsion by its charge and specific angular momentum

    Nonlinear scalar and spinor fields simulating perfect fluids

    No full text
    A possibility of simulating a perfect fluid using scalar and spinor fields with different nonlinearities is investigated. Exact cosmological solutions to Einstein's equations with the scalar and spinor fields are compared to the corresponding ones with a perfect fluid with a barotropic equation of state. © 2009 Pleiades Publishing, Ltd
