If matter and antimatter are gravitationally repulsive, then it would mean that the virtual particle-antiparticle pairs that exist for a limited time in the quantum vacuum are "gravitational dipoles." That is, each pair forms a system in which the virtual particle has a positive gravitational charge, while the virtual antiparticle has a negative gravitational charge. In this scenario, the quantum vacuum contains many virtual gravitational dipoles, taking the form of a dipolar fluid.
"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.
There's nothing about this sentence that isn't awesome:
"Dark matter may be an illusion caused by gravitational polarization of the quantum vacuum."

wow. head spinning. not just about the theory, but so many good "local band" names in there! quantum vacuum, dipolar fluid, etc. even "Hajdukovic said" has a certain ring to it...
Hey, I understood "If"!
Thanks for sharing! What an awesomely concise and clear article... This is now my new favorite explanation for dark matter - it just "feels" better than all that other stuff. I eagerly await experimental verification.
I'm not sure what you find awesome about the "may be", but the rest of it sure is. That's some serious technobabble.
Probably not. Because of mass-energy equivalence and inertial equivalence to rest mass.
The whole idea is flawed. Matter doesn't form gravitational dipoles; both matter and antimatter are equally attracted by gravity. On the other hand, as technobabble goes it's really good.
