"Our cosmos is much different," Aziraphale replies plainly. "Crowley here designed some of it, as a matter of fact. But humans have only been so far as the moon, and if there are any aliens, they haven't bothered to say hello, so we were looking forward to visiting a populated Alpha Centauri."

He'd like to see the stars that his demon made, too, but that's a different sort of journey. He smiles up at Crowley reassuringly. "Yes, perhaps. I'll ask him later. And if not, we'll think of something else. As Jim here says, there are all sorts of worlds out there. I'm sure we can find one where space travel and the divine co-exist."

He returns his attention to Jim, existential concerns shunted off for the time being. This is the man's wedding reception, after all, it's important to keep the conversation light. "Ah, that's so many! How are you all able to get along?" An idea occurs to him and he asks animatedly, "A universal translator, perhaps? Humans did so well before the Tower of Babel fell, didn't they, Crowley?"
