I’ve been a big fan of Doctor Who ever since I was terrified by the Yeti, the Ice Warriors and the Cybermen when I was four, but although the Doctor is a time traveller, in the original series (1963-89) the show rarely tackled the machinations and complexities of time travel itself. However in one particular 1972 story, Day of the Daleks, the question was raised as to why a time traveller couldn’t simply go back and nip a potentially terrible situation in the bud before it developed – and furthermore, why, if they failed the first time, they couldn’t keep going back.
The obvious answer, in reality, is that such an ability would completely negate the drama and excitement of pretty much every story. The Doctor, however, came up with a catch-all phrase, a kind of cosmic or temporal rule, whereby continually revisiting the same timeline in order to change it was an impossibility presumably imposed by time itself. He called it the Blinovitch Limitation Effect.
When writing my OBSIDIAN HEART trilogy, I too had to consider not only this question, but countless others. The more I delved into the intricacies of time travel – its possibilities, its anomalistic qualities – the more I became convinced that time travel was, and always would be, impossible. For instance, if we were able to time travel, we would all be able to become multi-millionaires overnight by literally creating money out of nothing. How, you may ask. Well, consider this. Imagine if the present you was visited by a future version of you from (let’s say) ten years hence with a suitcase containing twenty million pounds. With that amount of money you could not only live comfortably off the interest, but you could also generate more money – a lot more money! – and then in ten years time all you would have to do would be to fill the suitcase you’d been given ten years earlier with twenty million pounds, and go back to give it again to your younger self – and on and on, ad infinitum.
Of course, if everyone did this it would lead to massive problems – economies crashing, money becoming worthless – but then that would change the future, which would mean that your future self couldn’t appear to you in the first place, thus creating an anomaly. But what if the item was smaller, less influential? What if your future self appeared, gave you a pen, and said, “Keep this for the next twenty years, and then on October 10 2036 travel back to October 10 2016 and give your past self this pen and the exact same instructions I’m giving you.” The question then, of course, would be, where did the pen come from? Where and how and when was it made? Because it only exists in the twenty year time loop as your possession, forever being passed back to your younger self. Which ultimately means it – like the money – was created out of nothing!
You can tie yourself in knots with this stuff – and I frequently did during the writing of OBSIDIAN HEART. Hopefully I managed to negotiate a safe route through the minefield, though as it’s such a complex subject there is always the possibility that I overlooked something. I guess only time will tell.
