Dark Matter

I have had my evening Curry and elected to further stimulate my simple brain by watching The 'Sky at Night'. Its all about Dark Matter, if I am reading it right there is more of this stuff than adds up, that's allowing for the mass of all the planets, Galaxies etc combined and the assumed gravity they create to hold themselves in place. So in essence there's more Dark Matter than anything else, I suppose its like saying Galaxies are like leaves floating in a swimming pool, and Dark Matter is the water?. I think I can live with that, but am now confused about the old Matter/Anti Matter theory, e.g. everything has an opposite, to balance out out universe, you could extend this theory in Sci Fi terms to alternate universes for example. But surly this now all goes to pot if the bulk of our universe in Dark Matter?. One thing I really believe is that all those physicists at 'Cern' must have thought all their Christmases must have come together when they got all those governments to fund their underground Toy, searching for this so called 'Higgs' particle (and have found frankly, bugger all). Truly what an absolute waste?, they could have spent all of that money on something that we know exists, like refining Atomic fission for the masses?, or how to make the perfect Curry?, something which I am well on the way to actually proving; so thats a little bit more than those bloody useless physicists are doing at the moment?....
