 One can find Malament-Hogarth spacetimes which can escape both of the problems mentioned above (Manchak 2010; Andréka et al. 2018). For example, let \(M\) be a two-dimensional plane in standard \(t, x\) coordinates which is then “rolled up” along the \(t\) axis. Let the metric \(g\) be such that the light cones are oriented in the \(t\) direction and do not change from point to point. (See Figure 2.3.1.)
