I didn't realise that posting a link to an article would end in a virtual barnie!!
When I did my Cosmology course I found it very interesting and I was amazed that I could study a subject in which about 95% of matter/energy in the Universe was not really understood. I know we can see the effects of Dark Matter but I don't believe anybody has actually detected any. A bit like wind - you can see/feel the effects of wind but can't actually see it...
