Well, all right. I can't tell you how it works, really. I sort of accidentally caught a ride with the Doctor -- not the one who's here, if you've met him, that's another story entirely. His ship, the TARDIS, is the one who does all the time and space work. Although the Doctor is terrible at steering.
