Will such travel invoke [[paradoxl paradoxes]], such as often used in [[Time travel in fictionl fiction]]?) Some theories, most notably [[special relativitylspecial]] and [general relativity, suggest that suitable geometries of [[spacetime]], or certain types of motion in [[space]], may allow time travel into the past and future if these geometries or motions are possible == Physics- tAlbert Einstein]] 's [[Special relativitylspecial theory of relativity]l (and, by extension, the [LGeneral relativityl general theor]) very explicitly permits a kind of [time dilation] ] that would ordinarily be called time travel. The theory holds that, relative to a stationary observer, time appears to pass more slowly for faster-moving bodies: for example, a moving clock will appear to run slo as a clock approaches the speed of light its hands will appear to nearly stop moving. The effects of this sort of time dilation are discussed in the](https://i.kym-cdn.com/photos/images/newsfeed/000/159/811/37ad733142bb070213158d2dbca3f34d.jpg "37ad733142bb070213158d2dbca3f34d.jpg")
