Five-space math. Not a term he's familiar with, but probably just a different way to understand wormholes rather than an indicator that they might work in a different way altogether, here -- but who knows.

"It's what we use for translight travel." Wash isn't an engineer or a physicist, doesn't know the in-depth mechanics of it all beyond being able to rattle off what he's read about, but he knows the principles of how everything works well enough. "The FTL drive generates microscopic black holes and manipulates them into a slipspace rupture -- a wormhole. Jumps can take months, and they can be imprecise. They're stable, unless something goes wrong."

A pause. "Would you happen to know enough five-space math to know if that makes sense -- here?" In this. Reality. Or whatever this is. He'd still rather not jump to conclusions.
