“Weird the things that get to you when you’re a kid,” Jim said. “I knew it wasn’t for real. I was young, I wasn’t dumb. But it still scared me, and the thing my dad told me that actually got me past it? He showed me how it wouldn’t scale.” “Wouldn’t scale?” “Volume goes up by cubes. A cat big enough to crush a city wouldn’t be strong enough to stand up, even at Martian gravity. Its bones would break under its own weight. And that did it for me. I was all right, because I saw it couldn’t work. This is like that cat, it doesn’t scale.”
