This chapter argues for a notion of time that allows time travel. In order to time traveling to happen, in contrast to Presentism, the chapter demonstrates that we can change the past and we have some place where to travel. It shows the advantages of a non-presentist ontology that advocates for indeterminacy of future facts based not on its absence of truth-value, but on the overdetermination of future facts. The conclusion is that to break the causal chain is impossible in we are placed in the same causal line. But if we rethink the time traveling as a trans-world traveling, it is possible to open a new causal line anytime that someone travel in time, to the past as well as to the future.Even if some time soon our physicists find that the laws of physics support time travel, it might nonetheless never occur because, say, it will never be technologically feasible. Moreover, problems connected to time travel are not just empirically motivated, but they are also metaphysically and logically driven. In such a way that even those who see how deep and serious these problems are must admit that the existence of scenarios in which time travel is a possibility, it brings light over questions such as the nature and the topology of time, the time-asymmetry of causation, of backward causation, and some others.
