Explore 70 time travel writing prompts inspired by parallel timelines, temporal paradoxes, alternate histories, forgotten futures, and retrofuturist worlds where time itself has become unstable. This collection includes plot hooks, opening lines, title ideas, character prompts, setting inspiration, and cinematic picture prompts designed to help writers create atmospheric speculative fiction shaped by consequence, memory, and shifting realities. Inspired by stories such as The Time Machine, Dark, Interstellar, Back to the Future, and A Sound of Thunder, these prompts explore collapsing timelines, commercialised time travel, luxury temporal tourism, historical interference, looping realities, and the emotional cost of changing the past. Perfect for speculative fiction writers, worldbuilding, classroom writing, and science fiction storytelling focused on time, identity, and cause and effect.
