Ah... prenatal exposure, actually. Dust form element zero, since my mother happened to be in the right place at the wrong time when a shuttle's drive core blew. And if your reality hasn't discovered element zero... well, to explain it would take a while, but let's just say that one of the really interesting things about this whole falling through the multiverse thing is that I've now met four separate independent kinds of FTL travel beyond just how my reality does it.

It's hopeful, in a way. Humans will get to the stars one way or another, right?
