Never liked Wimps

BBC News - Dark matter 'beach ball' unveiled

This article talks about the inferred shape of the presumed dark matter around the Milky Way. It seems it's not like a round ball, but a squashed one.

This is why I've never felt that WIMPS (Weakly Interacting Massive Particles) seemed like a good explanation. I mean, if they exist, why do they form squashed ball halos around galaxies in the first place? If they are weakly interacting with normal matter, why don't they exist in just a more or less random clumpiness right through the universe? I don't know that I have ever read much that addresses that issue.

As for large clumps of normal matter forming dark matter, that's always seemed kind of unlikely too, according to my gut reaction.

That's why the idea that there is something wrong with our understanding of gravity has always seemed to me to be just as likely, but MOND theories don't seem to be advancing much.
