Dark Matter Question?

Question

According to the article here:http://www.astronomy.com/asy/default.aspx?c=a&id=4994 there are globs of dark matter floating around. If a space ship ran into them what would happen?

Answer 1

as far as we know dark matter does not have a physical manifestation in the dimensions that we observe. this 'map' looks to me like thethe shaded regions are where observation does not agree with predictions of gravitational effects on the mass which is present. so dark matter should be present here to make up for the gravitional effect which the mass alone does not provide. One theory is that the mass is in one of the other 10 or 11 dimensions other than x,y,z and time. so that we cannot observe it but we 'feel' the effects of it's gravitational pull. so to answer your question under this theory, it is impossible to run into the dark matter because it is tightly curled up in other dimensions, but if a spaceship were to enter these regions where unseen matter is present it would just feel the gravitational effect.

Answer 2

The truth is that we know very little about dark matter. So its hard to say what would happen.

On the other hand these globs of dark matter are not that dense, so I would guess that nothing major would happen.

Answer 3

I don't know much about dark matter,
but if its got gravity, then its got mass right?
so if something collided with it, ( at the speed space vessel would likely be traveling) then it would act like a bullet or cannon ball
