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
illusionor 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 arg
ument for the impossibility 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.
