| Jan 14, 2022 at 12:29 | comment | added | Nicolast | Yes, now you can add physical conditions. My point is that these conditions don't really make sense in higher signature. To put it differently, in signature $(p,q)$, $q\geq 2$, there are closed "timelike" curves in any neighbourhood of a point. | |
