The Tachyonic Antitelephone is a theoretical device from physics' history, a thought experiment realised. What if our future self could send back messages in time, telling us what our life could be, warning us of impending danger, or simply steering us away from mistakes and regrets. The Tachyonic Antitelephone opens up questions of free will, choice, fate and pre-destination. Can we change who we were, or who we may become? Do we really have the power to shift our own narratives?
