Abstract: (arXiv)
We discuss causality properties of asymmetrically warped space-times and argue that such scenarios may allow for timelike curves which can be closed via paths in the extra-dimensional bulk. We find a metric where the null, weak and dominant energy conditions are violated in the bulk, but satisfied on the brane. Such scenarios are interesting, since in principle gravitons or gauge-singlet (``sterile'') fermions propagating in the extra dimension may be manipulated in a way to test the chronology protection conjecture experimentally.- 04.50.-h
