We conjecture a topology-changing transition in M-theory on a non-compact asymptotically conical Spin (7) manifold, where a 5-sphere collapses and a ℂ P 2 bolt grows. We argue that the transition may be understood as the condensation of M5-branes wrapping S 5 . Upon reduction to ten dimensions, it has a physical interpretation as a transition of D6-branes lying on calibrated submanifolds of flat space. In yet another guise, it may be seen as a geometric transition between two phases of type IIA string theory on a G 2 holonomy manifold with either wrapped D6-branes, or background Ramond–Ramond flux. This is the first non-trivial example of a topology-changing transition with only 1/16 supersymmetry.
