    In Quantum Field Theory and in particles physics, there's a postulate that is SIMMETRY. Why exists this postulate?

    Best reggards.

    That's rather vague. You have to b more specific, in order to get a decent response.

    Symmetry is not postulated; it is rather an observation of the world's workings. It's importance lies in the fact that whenever a symmetry is found, an associated conservation law can be found as well (see Noether's theorem http://en.wikipedia.org/wiki/Noether's_theorem) [Broken]

    Symmetry is inherent to physical phenomena and nature in general.
