Is Dark Matter an Illusion?

Open access letter asks – Is dark matter an illusion created by the gravitational polarization of the quantum vaccum? by Dragan Slavkov Hajdukovic, CERN
Let us start with a major unresolved problem. The measured galaxy rotation curves remain roughly constant at large radii. Faster than expected orbits, require a larger central force, which, in the framework of our theory of gravity, cannot be explained by the existing baryonic matter. The analogous problem persists also at the scale of clusters of galaxies.
The favoured solution is to assume that our current theory of gravity is correct, but every galaxy resides in a halo of dark matter made of unknown non-baryonic particles (for a brief review on dark matter see for instance: Einasto, 2010). A full list of the proposed dark matter particles would be longer than this letter; let us mention only weekly interacting massive particles and axions. In spite of the significant efforts dark particles have never been detected…
The scientific inquiry process continues to be used to try and explain the evidence we gather. Unsettled areas of science show how difficult the discovery process is. Once we have settled on theories it is so easy to explain why basic truths of evolution, geology, chemistry… result in what the evidence shows. But getting to the scientific consensus is a challenging process.
For example, in 2006 astronomers unveiled a photo of two colliding galaxies known as the Bullet cluster that purportedly showed the separation of matter from dark matter. A similar effect was observed in the Pandora cluster earlier this summer, said Evans, who was not involved in the study.
Hajdukovic said he is currently expanding his theory to account for these observations. His preliminary calculations, he said, suggest that “what is observed in the Bullet cluster and more recently at the Pandora cluster may be understood in the framework of the gravitational polarization of the quantum vacuum.”
CERN physicist Michael Doser agreed that Hajdukovic’s ideas are “unorthodox” but did not immediately dismiss the new theory…
“In a few years,” Doser said, “we should definitely be in a position to confirm or refute [Hajdukovic's] hypothesis.”
