Abstract:
The possibility of time travel in modern physics based on the theory of relativity has led to the study of this issue from various aspects. In this research, the metaphysical possibility of time travel will be examined and therefore its physical and technological possibility is out of the subject of this research. Metaphysical possibility is also considered to mean the compatibility of time travel with the laws of metaphysics. The metaphysical possibility of time travel is challenged by the paradoxes that arise from it. These paradoxes, despite their great diversity, fall into four general categories: Temporal Paradoxes, The paradoxes of freedom, The paradoxes of Causal, and The paradoxes of identity. In this study, the paradoxes of freedom will be mainly examined. In these types of paradoxes, the simplest form of which is the famous paradox of the grandfather, a self-defeating act becomes possible. These themselves fall under the general paradoxes of past alteration, and the prevailing view is that the possibility of past change will lead to contradiction, and so the time travel is metaphysically impossible
