I love science and sciencefiction. Like many science fiction fans, I am fascinated by the possibility oftime travel. However, one must combine romance with reasoning and look into thechances of time travel critically.

First of all, we must rememberthe whole universe is in motion. If we want to go back to yesterday, our"time machine" has to move back in time and space. If someone claimedhe was at home when he suddenly travelled 200 years back in time, he either hadan illusion or made the story up. Two hundred years ago, Earth was in adifferent place in space, so how can you travel back 200 years without movingin space? Don't get me wrong. I am not knocking the genius of science fictionwriters. H.G. Wells's "The Time Machine" is a great work of fiction,but that’s all. I have read many other timetravelling science fiction stories since reading H.G. Wells, but none addressthis problem of displacement.

My own argument for theimpossibility of time travel is that physical states of the past no longerexist and those of the future are not here yet. To be able to move back andforth in time requires everything that has happened, is happening, and willhappen everywhere in the whole universe at every single moment in time－past, present, and future－to be stored as a "reality" somewhere－like the save game file of a computer game that contains everysingle byte of information of the game at the point it was saved, but you wouldneed an almost extremely large file and almost extremely many of them－so it can be re-entered and communicated with, and not just lightsignals for viewing. To me, I don’tbuy it.
