The most fundamental theory today that is substantially confirmed by experiment is the ``Standard Model'' of three interactions: electro-magnetic, weak nuclear and strong nuclear. In this model, particles like electrons, muons, neutrinos and quarks make up matter. They interact via the above forces. The force carriers are other particles, such as photons and the more recently discovered W and Z bosons and gluons. |
