Properties: it has mass (bends space)... don't know of any others, except the trivial stuff like it can move and be scattered around.

Effects: explains galactic rotation curves, explains some instances of lensing, possibly explains the perturbations this article is about.

Yeah, it has exactly the one property that someone is missing: mass. But is conveniently free of any other property that could influence anything.

The explanations you refer to are all based on calculations that are ultimately based on our understanding of gravity. The least understood force, the one that just won't fit into the picture. What a real scientist should do was to better research and explain gravity instead of making up some magic invisible soup to fix it all.

Pseudoscience, I say.
