For a few days now, I've been thinking of something I read when I was reading about Tolkien. As some of you may know, Tolkien was a Catholic, and he believed that the act of writing about Middle-Earth, detailing its history, customs, languages, and so on was ot just an act of literary exercise, but it was actually what he called a "sub-creation". Basically, as far as I understand, he believed that he was actually creating Middle-Earth on some level. From a religious point of view, this even makes sense: if, as the Bible says, we were created "in God's image", then it makes sense that we should be able to "create", after a fashion.
So I couldn't help but wonder, regardless of how silly it might be - what if the literary act of creating a whole world - not just a period or two, but a detailed world, with history, geography, races, and so on - were indeed an act of "sub-creation", indeed creating that world in a lower level of reality than we inhabit? What if, by creating a detailed world, the author were indeed creating it in a reality in which it has physical existence, and its inhabitants are as real to each other as we are to each other here?
It's definitely a weird thought, but the idea fascinates me. Some theories of physics suggest that the Universe is infinite, and therefore that whatever we can imagine exists somewhere (hey, words of physicists, not mine

)... the thought that by creating a world I'm actually giving it life somewhere, even if I were never able to actually see it, has something wondrous about it. Don't you think?
