Is Supersymmetry required by String theory?

[QUOTE="Demystifier, post: 6539092, member: 61953"] Non-perturbative formulation of bosonic string-field theory reinterprets tachyonic state as an unstable state, very much like tachyonic Higgs field before symmetry breaking is reinterpreted as an unstable state. By a process of tachyon condenzation the unstable state (local maximum of the potential) settles down into a stable state (local minimum of the potential) and excitations around the stable state are no longer tachyonic. So I would say no. But we still need susy in string theory because that's the only known way (as fas as I am aware) to incorporate fermions into string theory, and we need fermions because they are observed in nature.
