Universe Edge

I am fully aware that it is 2013 and the world didn't end and there are no humans on Mars and we aren't to futuristic yet. This whole story, apart from the theory of the ever expanding universe that will shrink and collapse on itself and cause a second Big Bang, bigger than the first, is fiction. Even my account of that theory is loosely based off of something I was told by a friend. I have no actual knowledge of this theory besides what was told to me by a somewhat reliable source. Do not quote me on any of the "facts" that are mentioned in the story, as they are most likely fiction.
