A massive bridge in China that cuts a two-hour journey down to two minutes looks like something from science fiction. But perhaps that’s the point. Humanity has a long history of turning the impossible into ordinary infrastructure — and if we can build wonders like this on Earth, what might we eventually achieve in space?
Excerpt: Science fiction readers are among the people most likely to underestimate the true scale of space. We are so accustomed to faster-than-light drives, wormholes and jump gates that we forget how impossably vast the distances between stars really are. But once a writer decides how long it takes to cross those distances, every other aspect of the story changes—from politics and trade to war, culture and the kinds of stories that can be told at all.
