This is probably my favorite song by my favorite band (but not necessarily my favorite song ever...). I think most people would agree this is just a huge, beautiful metaphor for the love the narrator has for his significant other. I think the idea of space travel is very romantic here because the idea is that their love cannot be confined by Earth, almost as if their love transcends Earthly understanding in some facet or another. In addition, the great expanse that space travel provides gives the listener the impression of separation from anything else of any significance and they just need each other.
