Technology News:Time Travel is Real.Here Are The People And Spacecraft Who Have Done It

Time dilation means when they return they're a bit younger than they would have been-as if they have traveled in to the future. (the effect is very small- it would take more than 100 years on the ISS to warp ahead by just one second) but not all travel spaces will keep you young.same as speed ,gravity also slower time,so your clock revs up as you get farther from a large mass like earth.

as the out come,satellites in highest orbits age more quickly. you had get heart set on space travel but want to age at a normal, earthly pace? good news! there's sweet place, 3174 KM above Earth's surface,where the effects of increased speed & reduced gravity cancel each other could hang there as long as you like without fear of relativistic shenanigans .
