Short stories that will, ultimately grow long in the telling. For example the longest short story in the history of the Universe is one Helluva BigBang. Question is, was any species actually there to hear it, and more cogently; as this creation / extinction event occurred in the almost total vacuum of space did you hear anything? Or see colours / fireworks? Feel a thrill of frisson? Me, I just slept through it all, but then I was a babygod.
