If we leave aside the gravitational force, and concentrate on the nuclear or strong force, the electromagnetic force, and the weak or radioactive force, then currently all experimental facts are explained by what is known as the Standard Model. We know experimentally that there are three families of quarks and leptons. We don't know why nature provides two more duplicate and apparently unused families.
Many theoretical proposals exist for extending the model, but none is universally accepted.
It is the task of the experimentalist to provide the correct clues for the next solution. At present, there remain to be discovered some outstanding pieces in the Standard Model, most notably the top quark, and the mysterious Higgs boson, which gives mass to all our particles, is still illusive. In order to extend our knowledge the experimentalist, broadly speaking, has a three pronged attack. Until a few years ago, a Victoria group was involved in the UA1 experiment at CERN, studying the highest energy accelerator collisions. These experiments will be possible at new accelerators, the SSC in USA and LHC in Europe just before the turn of the millennium.
