Scientific paper

We recently presented a model of a compactly generated and topologically trivial time-machine spacetime which satisfies the weak energy condition all the way up to the critical time slice (achronal hypersurface) in which a closed causal curve appears. Here we modify the above model so as to satisfy not only the weak energy condition, but also the dominant energy condition, up to that critical time slice.
