Just an FYI:
CERN physicist Dragan Slavkov Hajdukovic has proposed that the illusion of dark
matter may be caused
by the gravitational polarization of the quantum vacuum.
"We can consider our universe as a union of two mutually interacting entities,"
Hajdukovic said.
"The first entity is our 'normal' matter (hence we do not assume the existence
of dark matter and
dark energy), immersed in the second entity, the quantum vacuum, considered as
a sea of different
kinds of virtual dipoles, including gravitational dipoles."
He goes on to explain that the virtual gravitational dipoles in the quantum
vacuum can be
gravitationally polarized by the baryonic matter in nearby massive stars and
galaxies. When the
virtual dipoles align, they produce an additional gravitational field that can
combine with the
gravitational field produced by stars and galaxies. As such, the
gravitationally polarized quantum
vacuum could produce the same "speeding up" effect on the rotational curves of
galaxies as either
hypothetical dark matter or a modified law of gravity.
Abstract
Assuming that a particle and its antiparticle have the gravitational charge of
the opposite sign,
the physical vacuum may be considered as a fluid of virtual gravitational
dipoles. Following this
hypothesis, we present the first indications that dark matter may not exist and
that the phenomena
for which it was invoked might be explained by the gravitational polarization
of the quantum vacuum
by the known baryonic matter.
