How do you research the physics elements of your books? How much would you say you later the laws of physics, and how much do you respect them?
Specifically wondering about Skyward?
Brandon Sanderson
I, these days, am able to cheat on this a little bit, because I know I have a really good support structure of people who have actually studied physics, rather than myself, where I have flirted with studying physics. I am not a scientist, but I love pop science, if that makes sense. I'm the person who loves to read a book about someone doing science, but when I was a chemistry major in college, the actual physical labor of running experiments was mind-numbingly boring to me. And so I like to know. I like to know what rules I'm breaking, and how to play with them. But these days, I'm really able to trust my basic pop science studies. So, I'm not going to go read seven textbooks on physics. What am I gonna do? I'm gonna go to YouTube and say, "All right. What does it actually look like for someone to pull X number of g's." And I will watch those videos. (There's actually some really good ones on YouTube about that, specifically.) I'm going to go read blog posts, because our internet is so great, from pilots talking about their experiences. That's what I'm looking for. I'm not looking for what the physicist says happens. I'm looking for: how does a pilot describe it, and how is it presented for a layman.
And then, I am going to do my best and find experts to read the book for me and tell me where I'm wrong. I often say that you can get yourself most of the where there in research as an author with a minimal amount of time. You just need to find an expert, who spent all the extra time that it takes to become a true expert, to read your book and tell you where you're wrong. Preferably, a couple of people, because it turns out people in any profession disagree with one another greatly on some points, and it's good to know which points those are.
So, that's literally what I did for Skyward. YouTube videos, firsthand accounts, and a couple of pop culture essays. Stuff that's only, like, two to five thousand words long, about what the experience feels like and why it's working like it's working. Followed by getting some physicists and some fighter pilots both to read my early draft and tell me what I was doing wrong.
How much do I try? Sanderson's Zeroeth Law says "always err on the side of what's awesome." What this means for me, realistically, is: I want to tell a good story. And telling a good story takes precedent over basically anything else. That means that I don't want to break laws for physics for no reason, and I want to know when I'm breaking laws of physics. But I am going to find a cheat that lets me tell the story the way I want to tell it, if there becomes a conflict. The most famous one for me of this is the redshift that would happen when you make time bubbles in Era 2 of Mistborn. When I was working on this and researching it and be like "what would actually happen," turns out that a lot of the research I was reading said that you would redshift the light, and you would really have a chance of irradiating everybody outside or inside the bubble, depending. And I just had to say, "You know what? I've gotta come up with a law in the magic system that fixes this and makes it not happen. Because otherwise, I just can't do the magic, right?" That was good for me to know, but it's also a place where I just decided to cheat. And we can, as fantasy authors, cheat.
