Time Travel ... is it really possible?

Time travel has occurred in numerous science fiction films ranging from the classic HG Wells "The Time Machine", to the excellent television show Doctor Who. Usually when time travel appears in Sci-Fi there is very little description of how it's actually being done. In reality, time travel is not impossible - you're doing it right now, moving through time at constant rate of 1 day every day. The science of time travel is complex. This is not aimed at being an academic site with lots of equations, it's aimed at the novice. Therefore we have written both a simple explanation and a more detailed explanation. If you're interested in finding out more about time travel then the only place to look is books.

We have received lots of e-mail on the subject of time travel and we welcome more, but please do check out our time travel FAQ before contacting us - thank you.
