(4,949 posts)Cold Dark Matter particles float around in/all over space and on a large scale they interact somehow with gravity. Ther is overwhelming indirect evidence that Dark Matter exists. Weakly Interacting Massive Particles (WIMPs) probably interact via the Weak force somehow maybe with gravity. So the many detectors that experimentalists have set up inside mountains, mines, in outer space (The Alpha Magnetic Spectrometer) are searching for particles that leave some evidence of interacting with the detectors. Some detectors, for example, look for vibrations or signatures of WIMPS as they "bump" into crystal molecules and cause vibrations. Dark Matter particles do not interact with the electromagnetic force hence they cannot be seen.
Yes we were taught that the Universe is made up of 4 forces. They make up the forces in the Standard Model. Dark Matter particles go beyond the Standard Model. (Einstein did not believe in physics beyond the SM.) And the Standard Model was never really complete but physicists hope that the Higgs boson would help in completing it. Yet some questions remain about the Higgs and some physicists think that there are really several Higgs-type bosons and that this will be a bridge to supersymmetry. The mass of the Higgs boson that was found at the LHC last year falls exactly where a certain group of supersymmetry physicists predicted it would be.
This year and the next few years some aspects of physics will become clearer.
