@wikipedia:
…"a closed timelike curve (CTC) is a world line in a Lorentzian manifold, of a material particle in spacetime, that is "closed", returning to its starting point. This possibility was … later confirmed by Kurt Gödel … If CTCs exist, their existence would seem to imply at least the theoretical possibility of time travel backwards in time" …
