is dark matter attracted by ordinary massive objects?

If dark matter only responds to gravitational force it should accumulate around any massive object. How is a dark matter particle different from a particle of dust, for instance (except I suppose for size)? Presumably a massive object like Jupiter, as it drifts through ubiquitous dark matter, should sweep up the stuff and get more and more massive until it becomes a black hole. This has not happened, so something is wrong with my suggestion. So, why doesn't dark matter accumulate at the center of stars etc?

A good question.

Dark matter, if it exists, does interact with normal matter through the
weak nuclear force (a very short range force) and gravity.

I suspect that dark matter, if it exists, interacts with itself with a
repulsive force not associated with it's gravity. So no clumping of
dark matter with itself. This seems to fit the model but that repulsive
force would have to be a force that has no analog in normal matter.

There are current discussions regarding dark matter in sci.astro.
research you should look there.

AA I now can safely predict the Dark Matter Theory is N.G. Just the idea that 94% of the universe is missing proves how bad it is. I'm starting to get the true picture,and will post it.TreBert
