We like science fiction an awful lot on this blog, squiders, and I, at least, also like a good time travel story.
(If you’ve been around here for a while, you’ll know I come back to this topic every few years.)
Time travel can take a ton of different forms, of course, from being the main mechanism in a story to just some flavoring for another type of story (historical fiction, romance, etc.). So I was a bit amused recently when I found myself reading two different books, written almost 40 years apart, that used the same time travel mechanics, and ones that I’m not sure I’ve seen a lot elsewhere.
The books in question are Version Control (Dexter Palmer, 2016) and Thrice Upon a Time (James P. Hogan, 1980).
(I suppose this could potentially be spoiler-y, so read with caution.)
In both, time travel is treated very scientifically, with proper skepticism and with believable limits on how far you can go back and how the mechanism works. As such, we’re not jetting back to the Middle Ages or going back to assassinate Hitler or anything of that ilk. (Version Control deals with a limit of a few years, while Thrice Upon a Time deals in months.)
But both also include the fact that the new timeline overwrites the old timeline. Change something in the past, and the future that did the changing never existed. Not even the time traveler remembers.
(This is handled masterfully in Version Control, and even though I’m a bit sad about the ending–especially since there was another option–I understand why it went the way it did.)
So there’s no hints that the timeline has been changed (unless there’s a purposeful message left–in Thrice Upon a Time messages can be sent from the future to the past, but the act of sending/receiving the message is what erases the previous timeline) and no way for the people in the new timeline to know what happened on the original timeline or what, specifically, has been changed.
So it opens up very interesting questions like: what if you actually made things worse? How can you tell if it’s worth the risk to change the past when your present will no longer exist? If you did change that one event, would you actually accomplish what you meant to?
And no way to test, because the previous timeline is gone and can’t be recovered.
Very interesting take on the concept. Less adventure, more think-y.
I enjoyed Version Control and am not quite done with Thrice Upon a Time, though at this point I’m not sure if I would recommend it. It gets bogged down in long infodumps in the first half of the book, but has improved now that we’re finally using the time travel concept instead of just talking about it.
Know another book that uses this same time travel mechanic, Squiders? Read these books? Thoughts?
