String theory's applications are remarkably wide. Unfortunately its been beaten in the nuclear domain, where physics on a lattice QCD are more acclaimed as well as in cosmology where GR regns supreme.
The lattice theorists call it "dead" to cement their superiotity, some of its found ing developers abandoned it (Smolin) but its still breathing.. I. E see Vasilakos recent article on cosmic string signatures in Nanograv grav. Waves signal analysis.
So what is the non foe-based status of the theory in these domain?
