CERN Physicist Says Dark Matter May Be an Illusion

Not exactly. The article states that physicists assume a positive charge for gravity throughout the universe. Hajdukovic, the guy that wrote the paper (I think), suggests that a negative charge exists, just like with electromagnetism. He suggests that matter produces positive gravity, and antimatter produces negative gravity. Here is an excerpt from

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.
