A '''temporal paradox''', '''time paradox''', or '''time travel paradox''', is a [[paradox]], an apparent contradiction, or logical contradiction associated with the idea of [[time travel]] or other foreknowledge of the future. While the notion of time travel to the future complies with the current understanding of physics via relativistic [[time dilation]], temporal paradoxes arise from circumstances involving hypothetical time travel to the past – and are often used to demonstrate its impossibility.
