It might be interesting to note that the mentioned time travel paradoxes can be solved by using probablistic states (as multi-valued interpretations of quantum mechanics would imply would be the case in any real system with time travel). And that this results in a computational system that can solve &#x27;uncomputable&#x27; problems like the halting problem. See https://arxiv.org/abs/1609.05507. Time travel is really fun to think about in a computational setting!</p><p><a href="https://hackerpaper.kaipfister.de/p/1609.05507/">Paper and discussion history</a>.
