 It is a simplified, two-dimensional version of the Taub-NUT spacetime.It contains a non-curvature singularity and is an important counterexample to various hypotheses in general relativity.The simplest description of Misner space is to consider two-dimensional Minkowski space with the metric

with the identification of every pair of spacetime points by a constant boost

It can also be defined directly on the cylinder manifold formula_4 with coordinates formula_5 by the metric

The two coordinates are related by the map

and

Misner space is a standard example for the study of causality since it contains both closed timelike curves and a compactly generated Cauchy horizon, while still being flat (since it is just Minkowski space).
