Abstract

A new paper by Germain Tobar et al seem interesting, that they claim that reversible dynamics of CTC is possible. We comment this paper by pointing out at least 4 issues that make this paper problematic, not only practically but also conceptually.

Keywords: reversible dynamics; CTC metric
