There's 'Slaughterhouse - Five' by Kurt Vonnegut. The main character, Billy Pilgrim, becomes 'unstuck in time' and experiences different moments of his life, including his time as a prisoner of war during World War II, in a non - linear fashion. 'Time After Time' is another interesting story where H.G. Wells follows Jack the Ripper through a time machine into the future. These science fiction time travel stories often explore themes like causality, the nature of time, and the impact of small changes on the grand scale of things.
One of the most well - known is 'The Time Machine' by H.G. Wells. It's about an inventor who travels far into the future and discovers a world divided between the Eloi and the Morlocks. Another great one is 'Back to the Future'. Marty McFly travels back in time in a DeLorean and has to make sure his parents fall in love to secure his own existence. And then there's 'Doctor Who', which features a Time Lord traveling through time and space, having various adventures and facing different alien species along the way.
A classic is Ray Bradbury's 'A Sound of Thunder'. Hunters travel back in time to hunt dinosaurs. But when one of them steps off the path, it causes a ripple effect that changes the present. '12 Monkeys' is also notable. A convict is sent back in time to try to stop a virus from wiping out most of humanity. The story is complex and full of twists. 'Star Trek' also has some time - travel episodes, like 'Yesterday's Enterprise', where the appearance of an Enterprise from the past changes the future of the Federation.
