アブストラクト: We present two profound tunneling phenomena in 6d Toy Model of Flux compactification. The first is a non-perturbative instability of the flux vacua, where the tunneling is achieved by dropping all the flux altogether and tunnel to no-flux state. We found that this state is a state with no (classical) space-time. It is a tunneling to Nothing, i.e., a bubble of nothing (reminiscent to the Wittens bubble of nothing). The second is the reverse-process, i.e., that the flux vacua can be spontaneously created from Nothing. We dubbed it Bubble from Nothing. Finally we show that a bubble from nothing is stable against nucleation of bubble of nothing, and in fact there is a smooth transition between the two.
