E.g. bosonic string theory contains a tachyon which we interpret as nonstability of the vacuum, but which vacuum? Its the vacuum of the string field we're talking about, the perturbations of which are given by stringy amplitudes. Also AdS/CFT based models try to capture nonperturbative behaviour suggesting that there could be a nonperturbative extension. | |
