The spacetime of [arXiv:1103.1373] supposedly admitting closed timelike curves (CTCs) is flat spacetime with a compactified coordinate, and can only contain CTCs if the compact direction becomes timelike. The analysis of [arXiv:1103.1373] suggesting the generic existence of CTCs is based on misconceptions about general relativity: There is no time travel for Higgs particles, unless the world is periodic in time.
