Although the Standard Model is believed to be theoretically self-consistent and has demonstrated huge successes in providing experimental predictions, it leaves some phenomena unexplained and falls short of being a complete theory of fundamental interactions.
Iako se veruje da je standardni model teoretski samodostatan i da je pokazao ogromne uspehe u pružanju eksperimentalnih predviđanja, on ostavlja neke od fenomena neobjašnjenim i ne predstavlja kompletnu teoriju fundamentalnih interakcija.
