  The question of a possibility of opening a wormhole due to the deformation of
the equation of state of the matter caused by quantum gravity effects is
considered. As a wormhole environment, the previously considered model of a
galaxy with radial flows of dark matter is selected. The calculation shows,
that for a wormhole solution in the framework of this model, after the nominal
classical density exceeds a critical value in the Planck range, the components
of the energy-momentum tensor become negative in a certain order. First, the
mass density becomes negative, then the radial pressure, then the tangential
pressure. In this case, at some point the flare-out conditions necessary and
sufficient to open the wormhole are fulfilled. Calculations are made to open a
wormhole in a model with parameters of the Milky Way galaxy. It is shown that
the opening of the wormhole is accompanied by a separation of the bubble of
space, completely detached from the wormhole and the outer space. In addition
to this solution, a topologically dual one is found, looking like an instant
swapping of two volumes in space, which can be interpreted as an event of
teleportation.
