题目内容
I love science and science fiction. Like many science fiction fans, I am fascinated by the possibility of time travel. However, one must combine romance with reasoning and look into the chances of time travel critically.
First of all, we must remember the 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 claimed he was at home when he suddenly travelled 200 years back in time, he either had an illusion or made the story up. Two hundred years ago, Earth was in a different place in space, so how can you travel back 200 years without moving in space? Don't get me wrong. I am not knocking the genius of science fiction writers. H.G. Wells's "The Time Machine" is a great work of fiction, but that’s all. I have read many other time travelling science fiction stories since reading H.G. Wells, but none address this problem of displacement.
My own argument for the im
p
ossibility of time travel is that physical states of the past no longer exist and those of the future are not here yet. To be able to move back and forth in time requires everything that has happened, is happening, and will happen 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 every single byte of information of the game at the point it was saved, but you would need an almost extremely large file and almost extremely many of them－so it can be re-entered and communicated with, and not just light signals for viewing. To me, I don’t buy it.
