Abstract

We point out that the metrics recently proposed [K. Balasubramanian and J. McGreevy, arXiv:1111.0634] as gravitational duals to Lifshitz Chern-Simons gauge theories contain both a hidden null singularity and a region of closed timelike curves accessible to asymptotic observers. Like the singularity in the original Liftshitz spacetime given by Kachru, Liu, and Mulligan, this singularity does not include large $α^{'}$ or $g_{s}$ corrections and hence appears to be singular in string theory as well as classically.
