I have a question about our time-traveling. When we go back in time, are we there as just observers (as in, unseen, invisible to everything in the world at that time) or are we actually able to interact with other people and animals and things? It would be more fun if it was the latter, but we'd also have COMPLETELY, UTTERLY screwed up all of Time, past, present, and future, by now.

@Nerminator. Oh my gosh, I've read the story you're referencing with the squished butterfly, but I can't think of what it was called. We had to read it for English in 9th grade and it inspired me to write a story like that about a little girl who went back in time to warn Julius Caesar and the ensuing chaos and disturbances.
