AbstractThe continuation of Misner space into the Euclidean region is seen to imply the topological restriction that the period of the closed spatial direction becomes time dependent. This restriction results in a modified Lorentzian Misner space in which the renormalized stress-energy tensor for quantized complex massless scalar fields becomes regular everywhere, even on the chronology horizon. A quantum-mechanically stable time machine with just the submicroscopic size may then be constructed out of the modified Misner space, for which the semiclassical Hawking chronology protection conjecture is no longer an obstruction. © 1998 The American Physical Society
