One of the purposes of the new LHC at Cern is to search for dark matter. My understanding is that this has been so elusive thus far, because it has been completely undetectable by current technology. 'Normal' matter is completey oblivious to it and unaffected by it.
I understand that we are only aware of it's existence because the observed motion of galaxies cannot be explained just by the mass of the matter which we know about.
So how can it be that dark matter affects the motion of galaxies when 'normal' matter is not affected by dark matter? Because the we know the motion of observable matter in galaxies is affected by dark matter, am I not correct to suggest that it should be possible to detect dark matter?
I'm sure there's a simple explanation to this.
