I find it ironic that this article features a picture of data on the Bullet cluster, which is currently one of the strongest pieces of evidence favoring dark matter as a form of matter. Hajdukovic is quoted as saying that he's "currently expanding his theory to account for these observations." That translates as "I haven't found a compelling way of explaining them yet." It's great that he's considering alternatives to the usual approach, and it would be fantastic to have a second viable model to test observations against: competing theories encourage open-mindedness. I'm really happy to have his work up on the arXiv. But I don't believe that a speculative idea like this merits attention in the mainstream press until it can at least give plausible explanations for the major successes of existing models.
