Tomorrow Is Yesterday & Time Travel
Some theories, most notably special and general relativity, suggest that suitable geometries of spacetime, or specific types of motion in space, might allow time travel into the past and future if these geometries or motions are possible.16 In technical papers, physicists generally avoid the commonplace language of “moving” or “traveling” through time (‘movement’ normally refers only to a change in spatial position as the time coordinate is varied), and instead discuss the possibility of closed timelike curves, which are worldlines that form closed loops in spacetime, allowing objects to return to their own past. There are known to be solutions to the equations of general relativity that describe spacetimes which contain closed timelike curves (such as Gödel spacetime), but the physical plausibility of these solutions is uncertain.
So, there you go, time travel, will it become a cutting edge reality or stay in the minds of science and the pages of fiction forever?
Tomorrow Is Yesterday is the name of a Star Trek episode where Captain Kirk is thrown back in time to Earth in 1969.
