No, it would not be to recreate a Cher song. Or maybe it would. I’m not sure at this point because I have the stupid thing playing on a loop in my head right now.
Writing for futurism.com, Chelsea Gohd published a piece called “We Can’t Alter The Flow of Time But, According to Physics, We Can Bend It” a few days ago, and I lapped up every word.
We’ve all considered the notion of time travel at one point in our lives. Don’t deny it. Ever since that excellent! film (not movie) Back to the Future II, when Biff steals a sports almanac and goes back in time to make himself crazy rich, we’ve all entertained notions of joining the Biffs of the world.
As far as I understand – and with much of what I learned at M.I.T. relegated to the depths of the Mariana Trench – Einstein conceived of travelling forward in time (assuming we could reach the speed of light), but never back in time. He did leave open one possibility that even he could only speculate about: wormholes.
Although I’m generally apathetic when it comes to sci-fi literature and movies, I’ve been thinking a lot about the space-time continuum lately because of a Korean novel I’m helping to translate, author Kim Hee-sun’s The Multiverses of Infinity (무한의 책).
It goes without saying that I’m ecstatic to be part of a project I truly believe in and helping breathe life into it for English readers one day. (Think Kafka meets Murakami Haruki in a dark Prague alley, somehow the two speak the same language, and after a quick meet-and-greet of sorts, they decide to stroll off together to a Harajuku jazz club, where they will discuss beautifully shaped ears and huge insects.) And since the plot of Multiverses involves a character going back in time, it’s got me thinking.
Without giving away too much of the plot, the central driving force for this character to go back in time is to help someone, not hurt them, and not to benefit in any selfish way like our friend Biff. If we as human beings ever do come up with a way to travel through time, I can’t help but wonder what our motivation would be.
Anyway, Ms. Gohd’s article on space-time is nothing short of fascinating and illuminating. And to quote Gohd quoting Stephen Hawking at the end, “Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.”
