answer:Of course, travelling into the future is trivial, since everyone is doing it all the time already. You might be able to move faster in time by moving faster in space, or by living in high orbit for a while¹, but you can achieve the same effects with cryogenic stasis. Get frozen up, take a nap, thaw, wake up. Congratulations, you are now in the future. Moving through time slower would sound like a more worthwhile thing to try, if for some reason you want to age faster than the rest of us. (Who knows, maybe you just really need to catch a deadline.) I recall reading somewhere – I think it was in a theoretical physics popular science book, probably Michio Kaku’s Hyperspace – that it would be theoretically possible to create a time machine that takes you into the past, but you could never travel further back than the moment the machine was created. _____ ¹ If I’m not mistaken. I always forget if being close to a heavy object makes time go faster or slower for you, so maybe it’s the other way around.
