We show that stable causality is related to the vanishing of the top Stiefel–Whitney class of a space-time manifold M, and that if M is a stably causal space-time manifold, then it is the boundary of a five-dimensional space-time. We then propose a

We start by reviewing the differential geometric setting for the matter fields, then discuss the wormhole metric and the time machine. Then we move on to the covariant derivates associated with the principal bundles erected to account for gauge and L
