Supersymmetry

The gauge symetry method for describing force and particles lead theorists (1970's) on a search to describe everything in terms of one great symmetry.
 
The only astmmetry left  was between  particles (fermions) and forces (bosons).

The theory that unifies these is called Supersymmetry or SUSY

               basicaly says for every fermion there is a bosonic supersymetric partener

SUSY reestablishes space-time/special relativity to the quantum level.
 
Very powerful theory  GUT s          ex.   N=8 supergravity

Broken symmetry?

Dark Matter?
