Yes, it does. Gödel found a solution to the Einstein field equations that shows that it is possible to have closed timeline curves on a cosmological scale under particular conditions. (The universe is rotating and has a carefully chosen value for the cosmological constant.) https://en.wikipedia.org/wiki/G%C3%B6del_metric https://en.wikipedia.org/wiki/G%C3%B6del_metric
