Soon afterward, the time traveler was identified as professional spammer Robert J. Todino (known as "Robby"). Todino's attempts to travel in time were a serious belief, and while he believed he was "perfectly mentally stable," his father was concerned that those replying to his emails had been preying on Todino's psychological problems.
Seth Lloyd proposed an alternative approach to time travel with closed timelike curves (CTCs), based on "post-selection" and path integrals. [19] Path integrals are a powerful tool in quantum mechanics that involve summing probabilities over all possible ways a system could evolve, even if those paths don't strictly follow a single timeline.

Time dilation is the difference in elapsed time as measured by two clocks, either because of a relative velocity between them (special relativity), or a difference in gravitational potential between their locations (general relativity).

A Tipler cylinder, also called a Tipler time machine, is a hypothetical object theorized to be a potential mode of time travel—although results have shown that a Tipler cylinder could only allow time travel if its length were infinite or with the existence of negative energy.
If mental time travel is unique to humans, then it must have emerged over the last 6 million years since the line leading to modern humans split from the line leading to modern chimpanzees. Perhaps the first hard evidence for the evolution of mental time travel in humans comes in the form of Acheulean bifacial handaxes associated with Homo ...
A time slip is a plot device in fantasy and science fiction in which a person, or group of people, seem to travel through time by unknown means. [12] [13] The idea of a time slip has been used in 19th century fantasy, an early example being Washington Irving's 1819 Rip Van Winkle, where the mechanism of time travel is an extraordinarily long sleep.
