In "The Miracle of Christmas", Episode 2.11 of the American TV series Timeless, a Tipler cylinder is mentioned as being added to an upgraded time machine. In season 2 episode 14 of "Gabby Duran & the Unsittables - Zeke to the Future" a Tipler's Infinity Cylinder is mentioned as a possible time travel device.
Seth Lloyd proposed an alternative approach to time travel with closed timelike curves (CTCs), based on "post-selection" and path integrals. [21] Path integrals are a powerful tool in quantum mechanics that involve summing probabilities over all possible ways a system could evolve, including paths that do not strictly follow a single timeline.

Time travel is the hypothetical activity of traveling into the past or future. Time travel is a concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a device known as a time machine. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time ...
Time travel can result in multiple universes if a time traveller can change the past. In one interpretation, alternative histories as a result of time travel are not parallel universes: while multiple parallel universes can co-exist simultaneously, only one history or alternative history can exist at any one moment, as alternative history usually involves, in essence, overriding the original ...

Time travel in modern fiction is sometimes achieved by space and time warps, stemming from the scientific theory of general relativity. [9] Stories from antiquity often featured time travel into the future through a time slip brought on by traveling or sleeping, in other cases, time travel into the past through supernatural means, for example brought on by angels or spirits.
It is the final part of the "Lazarus Long" cycle of stories, involving time travel, parallel dimensions, free love, voluntary incest, and a concept that Heinlein named pantheistic solipsism, or 'World as Myth': the theory that universes are created by the act of imagining them, so that somewhere (for example) the Land of Oz is real.
The means of traveling through timelines is a flying saucer-shaped "conveyor" [note 1] using the Ghaldron-Hesthor field generator, which was developed via a fortuitous fusion of attempts to develop faster than light space travel with ones attempting to explain certain psychic phenomena. Conveyors are fixed in place, which means that as they ...
